et al. Find the best of the best from your set of possible matches. Galaxy Zoo is described in Lintott et al. This includes coordinates, photometry, size, and redshifts (where present). CANDELS images were taken with both the ACS and WFC3 cameras on the Hubble Space Telescope, focusing on rest-frame optical wavelengths of galaxies at redshifts of 1 < z < 3. This sample of merging galaxies is assembled from SDSS Galaxy Zoo 1 data. This webpage allows anyone to download the resulting GZ classifications of nearly 900,000 galaxies in the project. Classify the morphologies of distant galaxies in our Universe It is a homogenous sample of galaxies (0.005 < z < 0.1) with spectroscopy for at least one of two merging galaxies in the pair. You decide which simulation wins in a series of tournament-style competitions. (2009). About Galaxy Zoo To understand how galaxies formed we need your help to classify them according to their shapes. ellipticals are red, This table includes raw and weighted morphological classifications for all tasks in the GZC classification tree for each of the 49,555 unique sources in the sample. Download here: schawinski_GZ_2010_catalogue.fits.gz. 2013. Table 7 contains classifications of 6,144 galaxies from the GOODS-N and GOODS-S surveys. 0 = no emission lines, 1 = star-forming, 2 = composite, 3 = Seyfert and 4 = LINER. (2010) and Lintott et al. This set of images had no adjustments made to its background, which resulted in coloured background noise for some galaxies. In conjunction with Galaxy Zoo 2, we ran a parallel project to measure lengths, widths, and angles of galactic bars using an interactive interface. History of Galaxy Zoo The launch of this new version of Galaxy Zoo, the 4th, comes just a few weeks after the site’s 5th birthday. al. The Story So Far Galaxy Zoo is now arguably the world’s best-known online citizen science project, and is certainly the one with the largest number of … 2008, MNRAS, 389, 1179 and the data release is described in Lintott et al. Table 6 contains classifications of 3,927 galaxies from the COSMOS survey. In short, we hope to find out everything there is to know about the appearance of galaxies! These tables are also accessible via CasJobs. In this table, each row corresponds to an individual galaxies and the columns to the various morphological parameters. It is a Zooniverse tradition to recognize their contributions as co-authors, and we gladly support that tradition. "Green peas" are compact galaxies with extremely high star-formation rates. Authors. red spirals are Data Collection Closed. The project description and data reduction is in Willett et al. (2010) and Select simulations that look similar to the targeted merger. Galaxy Zoo 2: detailed morphological classifications for 304,122 galaxies from the Sloan Digital Sky Survey, now accepted for publication in the Monthly Notices of the Royal Astronomical Society, is the result of a lot of hard work by Kyle Willett and friends. spirals is an 2013) and Galaxy Zoo 2 (Willett et al. This table gives the results from the bias study that introduced mirrored images. This table gives the fraction of votes in each of the six categories, combining results from the main and bias studies. New in SDSS Data Release 10 are more detailed classifications of internal structure of the brightest 25% of the Main Galaxy Sample from Galaxy Zoo 2 . (2016) table, as this debiases the GZ2 quetion tree most consistently. With so many galaxies, it had been assumed that it would take years for visitors to the site to work through them all, but within 24 hours of launch, the website was receiving almost 70,000 classifications an hour. population. ENGLISH| POLSKI. Catalogues of the galaxy properties, along with multi-wavelength coverage from radio through ultraviolet, are available here. optically red in 2013) publications if using this data. Images for GZH were taken from the Advanced Camera for Surveys (ACS) aboard Hubble, including data from multiple Legacy surveys. Look at telescope images of distant galaxies. The original Galaxy Zoo consisted of a data set made up of about 900,000 galaxies imaged by the Sloan Digital Sky Survey. Value-added GZ data includes the morphologies of the merging galaxies as well as the relative stage of the merger. Galaxy Zoo has been an attempt to get citizen science to classify all the galaxies present in various data sets, such as the Sloan and Hubble surveys, as elliptical, spiral, etc. The various overlapping galaxy pair types are illustrated in Figures 2a and 2b from Keel et al. As you answer, we lead you down a decision tree where the questions depend on how you’ve previously responded. (2009). below is from Appendix These images are shallow exposures created from 2-epoch imaging, as contrasted with the deeper 5-epoch imaging of galaxies from GOODS in Table 4. This section contains data from the Galaxy Zoo survey for overlapping galaxy pairs, useful for studies of dust absorption. More than 6000 users contributed to the project by running and reviewing simulations or by participating in Merger Wars. Table 6 gives classifications of the 42,462 galaxies in the main sample with photometric redshifts only. Take your best matches, and improve them by tuning your simulations. http://astronomy.ua.edu/keel/observe/PDFcharts, http://gz2hart.s3.amazonaws.com/gz2_hart16.csv.gz, http://gz2hart.s3.amazonaws.com/gz2_hart16.fits.gz, http://gz2hart.s3.amazonaws.com/gz2_hart16.vot.gz, Low mass sample (10.0≤log(Mstar)<10.34; N=789), Intermediate mass sample (10.34≤log(Mstar)<10.64; N=801), High mass sample (log(Mstar)≥10.64; N=790), Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS). The fraction of the vote in each of the six categories is given, along with debiased votes in elliptical and spiral categories and flags identifying systems as classified as spiral, elliptical or uncertain. For an interactive visualization of the decision trees for each of the Galaxy Zoo projects, please look at this tool created by Coleman Krawczyk (University of Portsmouth). These tables contain useful metadata matched to the morphological data in Tables 4–9. (2010b). This is the primary GZ2 data release, containing the largest number of galaxies and the most reliable morphologies. 2013, MNRAS, 435, 2835 — please cite this paper if making any use of the GZ2 data. It all started back in July 2007, with a data set made up of a million galaxies imaged by the Sloan Digital Sky Survey, who still provide some of the images in the site today. Zooniverse now offers several citizen science projects, including three more using NASA data. Galaxy Zoo - the project which harnesses the power of the internet - and your brain - to classify a million galaxies. The table names in CasJobs are: For any object in SDSS DR10, you can access its Galaxy Zoo or Galaxy Zoo 2 classifications (if present) by using the "Explore" tool. (2014) used GZ2 and preliminary GZ: Hubble data to study the evolution of the bar fraction in galaxies over cosmic timescales. Galaxy Zoo Mergers is now in an archive status. A1 and A2 in Masters These colour composite images had the red and blue channels swapped from default settings, and tested the effects of colour perception on morphological consistency. colour. If you're quick, you may even be the first person to see the galaxies you're asked to classify. If your science question benefits from having classifications from images comparable depth across an entire sample, we recommend using the. THIS SITE IS NOW ARCHIVED; go here for the Below are PDF files containing a single page for each galaxy pair, plus finding charts, more detailed photometry and identifications, and in some cases more precise redshifts. Properties of the initial sample are described in Cardamone et al. Justin is the project manager for Unearthing Michigan Ecological Data, a project that uses the Zooniverse crowdsourcing platform to identify data within a large collection of papers written by… Citizen Science. (PASP, 2013, 125, 923). The rows/columns are transposed from the version in the printed article (which was done only to illustrate form and content). After Galaxy Zoo kicked off, scientists began approaching Lintott at conferences asking for help. Table 6 - Main sample, photometric redshifts. The Galaxy Zoo team has run many projects that study the large-scale properties of galaxies, such as their shape, characteristics, and patterns in their behavior. (2016): we strongly advise the use of the Hart et al. The full set of results can be downloaded below. identified spiral structure which are Data is derived from the Zoo 1 and Zoo 2 periods (August 2007–April 2010), and is described in detail by Keel et al. As we approach the 8 th anniversary of the Galaxy Zoo project, it is a great opportunity to look back at one of the most fascinating discoveries of citizen science in Galaxy Zoo – the “Green Pea” galaxies. Galaxy Zoo 1 data are described in Lintott et al. Lead author Kyle, seen here taking a rare moment away from reducing Galaxy Zoo data. Galaxy Zoo is a website that asks members of the public to classify galaxies for us. Within the Navigator tool, you can create many different graphs from the data your group analyzes. colour, while most This site is still alive for nostalgia's sake, but your classifications will not form part of the public data release. so this sample of red 2011 , and details of the project are available in Linott et al. intermediate Melvin et al. He lead the data reduction and catalog creation from Galaxy Zoo 2 classifications, has worked on building new tools to enable independent research by citizen science volunteers and now leads efforts to include new data sets in Galaxy Zoo. (2017) (available both from arXiv or the MNRAS journal) describes the project and data release. There is a similar file of candidate pairs which were rejected for the final list because of evidence for interaction, other geometric reasons, or for having redshifts the wrong way around for dust backlighting. This is what See this page for full details and data for the separate Galaxy Zoo: Mergers project. Thank you again to all of our volunteers. Citizen Science. Please cite this paper if using any data from Galaxy Zoo: CANDELS. The magnitude limit for Stripe 82 classifications (r<17.7) is slightly deeper than the main samples. The data "Red Their name comes from their appearance in colour SDSS images, which is due to strong [OIII] λ5007 emission that appears in the r-band filter for large numbers of low-redshift (0.112 < z < 0.360) galaxies. Galaxy Zoo 2 (GZ2) was the successor project to Galaxy Zoo. spiral samples from Merger Wars. sample of normal blue For any use of data from this sample, please cite Darg et al. When using this sample, please cite Schawinski et al. interesting The Galaxy Zoo scientists have created a tool called Navigator that allows Zooites (Galaxy Zoo contributors) to form groups and analyze galaxies together. Spirals" are galaxies with clearly The Zooniverse is the world’s largest and most popular platform for people-powered research. Table 9 - Morphological classifications for co-added SDSS images of galaxies in Stripe 82. et Galaxy Zoo 1: data release of morphological classifications for nearly 900 000 galaxies ...

Such a database will have substantial legacy value for the international astronomy community. GZ: Hubble disk galaxy sample split into three stellar mass bins. These images were faded to very low colour saturation before classification, and tested the effects of colour gradients on morphological consistency. The table numbers below are the same as their order in the paper. Data below is from Table 4 in Cardamone et al. Just click the "Galaxy Zoo" link under "Imaging Summary" in the left-hand sidebar (example here). The Galaxy Zoo UI. Simmons et al. Shown here is a diagram of the classification scheme and decision tree used in GZ: Hubble. Most spiral October 14, 2016 — 0 Comments. spirals. To see the final data release visit the data page here. A Galaxy Zoo Timeline. Some of these galaxies also appear in the main sample (Table 5). Table 8 contains classifications of 21,522 galaxies located in SDSS Stripe 82. This table gives a series of measures of the classification confidence. The full data reduction pipeline and analysis codes for GZH are available as an open-source Github repository. These images tested the effects of optically-bright AGN on morphological classification. The closest excerpt I can find (p 142) is: "Like a computer, Galaxy Zoo can find patterns in large data sets, data sets far beyond the comprehension of any single individual. All of the data which is currently publicly available from any phase of Galaxy Zoo is available on our Data Archive site. The organization grew from the original Galaxy Zoo project and now hosts dozens of projects which allow volunteers to participate in crowdsourced scientific research. Table 8 gives classifications of the first set of 19,765 galaxies classified in the coadded (runs 106 and 206) Stripe 82 images. we need you now more than ever!. The Clump Scout project is a bit different because our focus is on a much smaller target. This table gives the results from the bias study that introduced monochrome images. Volunteers on the forum first noted these galaxies due to their peculiar bright green color and small size. CANDELS: The new data in Galaxy Zoo This post is the second of a series introducing the new Galaxy Zoo.The first is here, and you should come back in the next few days for more information about our fabulous new site. The Zooniverse is the world’s largest and most popular platform for people-powered research. Their names are: This sample is presented in the Galaxy Zoo 1 paper on AGN host galaxies (Schawinski et al., 2010, ApJ, 711, 284). This section contains data from the Galaxy Zoo survey for overlapping galaxy pairs, useful for studies of dust absorption. Information on more than 300,000 galaxies. Table 6 - Morphological classifications for recoloured galaxies. Dear Galaxy Zoo users, Galaxy Builder made use of citizen science to create disc-bulge-bar-spiral photometric models of 198 spiral galaxies, selected using GZ2 and the NASA-Sloan Atlas. Early Galaxy Zoo 2 classifications were used to identify a sample of 362 spheroidal galaxies with prominent dust lanes (DLSGs), ranging from redshifts of z=0.01 to 0.07. The first papers and follow-up observations are complete, and you can follow our progress on the BLOG and FORUM. This table gives classifications of galaxies included in the Galaxy Zoo sample which did not have spectra available in SDSS Data Release 7. This table provides pre-matched sets of metadata for the Galaxy Zoo 2 samples taken from DR7. October 13, 2014. These images provide a low-redshift counterpart to the data from the various Hubble surveys. The original Galaxy Zoo project ran from July 2007 until February 2009. The code used to reduce GZ2 is available on GitHub — please take a look either at its webpage or fork it from the repository if you're interested in the details. We show you a galaxy, and we ask simple questions about what you can see, like – is the galaxy smooth, or featured? A, Tables gives the red and blue The project is further described in Lingard et al. 2008 . Spectroscopic classification of galaxy based on emission lines ratios in the BPT diagram. Data is derived from the Zoo 1 and Zoo 2 periods (August 2007–April 2010), and is described in detail by Keel et al. This table gives classifications of galaxies which have spectra included in SDSS Data Release 7. 2012; Shabala et al. (2013) and Hart et al. This includes (where available) redshifts, magnitudes, angular sizes, automatically-measured morphological parameters, and additional flags from the parent surveys. In the end, more than 50 million classifications were received by the project during its first year, contributed by more than 150,000 people. This guest blog is by Justin Schell, who directs the Shapiro Design Lab at the University of Michigan Library and also co-hosts SciStarter’s podcast, Citizen Science. Table 8 - Morphological classifications for single-epoch SDSS images of galaxies in Stripe 82. Bios, Citizen Science. Please cite the DLSG (Kaviraj et al. compared to a match Table 5 contains classifications of 3,927 galaxies from the COSMOS survey. Galaxy Zoo 2 - which asks for more detailed classifications of roughly 250,000 of the brightest galaxies in our sample is now live. These represent the morphology (or shape) of the galaxy in 37 different categories as identified by crowdsourced volunteer classifications as part of the Galaxy Zoo 2 project. Table 8 - Stripe 82, coadded-depth (set 1). But (PASP, 2013, 125, 923). The images come from single-epoch observations by SDSS, but use the same decision tree and interface as the data in Tables 4-7. The current claim is based on a sample of just 1660 galaxies from the SDSS survey, but a much larger sample is required to assess the significance of the effect which is where Galaxy Zoo comes in. Table 9 contains classifications of 30,339 galaxies located in SDSS Stripe 82. Please cite this paper if using any data from the project. Citizen Science, Galaxy Zoo, Projects. Galaxy Zoo 2 - which asks for more detailed classifications of roughly 250,000 of the brightest galaxies in … SDSS model magnitudes. This includes galactic bars, spiral arm and pitch angle, bulges, edge-on galaxies, relative ellipticities, and many others. This was started in July 2007 and retired i… Coadded images are made from combining between 47–55 individual exposures, resulting in better detection of fainter features and improved seeing. described in Masters Debiased morphologies for this sample are slightly more uncertain than Table 5, since the data reduction requires a redshift to adjust the morphology for classification bias. Thanks for making Galaxy Zoo such a success! So go here to get classifying. Anyone making use of the data should cite at least one of these papers in any resulting publications.
