Raw and weighted classifications for the full Galaxy Zoo: CANDELS sample. The images come from single-epoch observations by SDSS, but use the same decision tree and interface as the data in Tables 4-7. In this table, each row corresponds to an individual galaxies and the columns to the various morphological parameters. In the original Galaxy Zoo project, volunteers classified images of Sloan Digital Sky Survey galaxies as belonging to one of six categories - elliptical, clockwise spiral, anticlockwise spiral, edge-on , star/don't know, or merger. Presented here are links to webpages with the HST postage stamp images for the different galaxy samples. These images provide a low-redshift counterpart to the data from the various Hubble surveys. 2012; Kaviraj et al. Coadded images are made from combining between 47–55 individual exposures, resulting in better detection of fainter features and improved seeing. 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. Table 8 - Morphological classifications for single-epoch SDSS images of galaxies in Stripe 82. All of the data which is currently publicly available from any phase of Galaxy Zoo is available on our Data Archive site. Minneapolis — St. Paul: More than 83,000 volunteer citizen scientists. This table gives the results from the bias study that introduced mirrored images. Select simulations that look similar to the targeted merger. (2008, 2011). Such a database will have substantial legacy value for the international astronomy community. A Galaxy Zoo Timeline. Galaxy Zoo is described in Lintott et al. Table 9 - Stripe 82, coadded-depth (set 2). Their names are: This sample is presented in the Galaxy Zoo 1 paper on AGN host galaxies (Schawinski et al., 2010, ApJ, 711, 284). With data on more than 300,000 nearby galaxies, the Galaxy Zoo 2 catalog is 10 times larger than any previous catalog of its kind.

For science cases, we encourage users to instead use the latest measurements from the latest data release. This was started in July 2007 and retired i… that work. It was replaced by Galaxy Zoo 2, Galaxy Zoo: Hubble, and Galaxy Zoo: CANDELS. This table gives a series of measures of the classification confidence. latest Galaxy Zoo project. Galaxy Zoo 1 data are described in Lintott et al. Table 10 contains classifications of 2,961 HST images that contain both a real galaxy and a simulated nuclear point source of varying intensity and colour. 2011 , and details of the project are available in Linott et al. (2017) (available both from arXiv or the MNRAS journal) describes the project and data release. Table 9 contains classifications of 30,339 galaxies located in SDSS Stripe 82. These tables contain useful metadata matched to the morphological data in Tables 4–9. See this page for full details and data for the separate Galaxy Zoo: Mergers project. If you're quick, you may even be the first person to see the galaxies you're asked to classify. (2016): we strongly advise the use of the Hart et al. Data Collection Closed. It is not possible to estimate the bias in this sample without accurate redshifts, and so only the fraction of the vote in each of the six categories is given. The PDFs are also available at http://astronomy.ua.edu/keel/observe/PDFcharts. red spirals are For any use of data from this sample, please cite Darg et al. Thank you again to all of our volunteers.

Images for GZH were taken from the Advanced Camera for Surveys (ACS) aboard Hubble, including data from multiple Legacy surveys. Merger Wars. The original Galaxy Zoo consisted of a data set made up of about 900,000 galaxies imaged by the Sloan Digital Sky Survey. Just click the "Galaxy Zoo" link under "Imaging Summary" in the left-hand sidebar (example here). intermediate Shown here is a diagram of the classification scheme and decision tree used in GZ: Hubble. Galaxy Zoo 2 (GZ2) was the successor project to Galaxy Zoo. October 13, 2014. It is a Zooniverse tradition to recognize their contributions as co-authors, and we gladly support that tradition. SDSS model magnitudes. 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. Galaxy Zoo 2 - which asks for more detailed classifications of roughly 250,000 of the brightest galaxies in … (2017) (available both from arXiv or the MNRAS journal). This table gives the results from the bias study that introduced monochrome images. identified spiral structure which are 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 … Galaxy Zoo: Hubble used data from the Hubble Space Telescope to classify images of distant galaxies beyond the reach of SDSS. 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. Citizen Science. optically red in This is what But we need you now more than ever!. 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 . Classify the morphologies of distant galaxies in our Universe Galaxy Zoo 2 - which asks for more detailed classifications of roughly 250,000 of the brightest galaxies in our sample is now live. Some of these galaxies also appear in the main sample (Table 5). The full reduction and analysis of GZ: Hubble was published in Willett et al. The Clump Scout project is a bit different because our focus is on a much smaller target. gives the red and blue 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. We show you a galaxy, and we ask simple questions about what you can see, like – is the galaxy smooth, or featured? Most spiral Classifications and depth-corrections for 10,648 galaxies in GZC that had imaging at multiple co-added epochs. The GZ2 catalog is also accessible via CasJobs in Data Release 10. These images tested the effects of optically-bright AGN on morphological classification. al. Volunteers on the forum first noted these galaxies due to their peculiar bright green color and small size. But More than 6000 users contributed to the project by running and reviewing simulations or by participating in Merger Wars. The magnitude limit for Stripe 82 classifications (r<17.7) is slightly deeper than the main samples. 0 = no emission lines, 1 = star-forming, 2 = composite, 3 = Seyfert and 4 = LINER. 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. et al. This is the primary GZ2 data release, containing the largest number of galaxies and the most reliable morphologies. These images were faded to very low colour saturation before classification, and tested the effects of colour gradients on morphological consistency. Table 6 - Main sample, photometric redshifts. we need you now more than ever!. Bios, Citizen Science. The project is further described in Lingard et al. 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. This paper presents the first results from a new citizen science project: Galaxy Zoo Supernovae. Data is derived from the Zoo 1 and Zoo 2 periods (August 2007–April 2010), and is described in detail by Keel et al. Table 7 gives classifications of the 17,787 galaxies classified in single-depth Stripe 82 images. (2011) for a description of the project and scientific results. The Zooniverse is the world’s largest and most popular platform for people-powered research. Galaxy Zoo Mergers is now in an archive status. (2009). Table 5 contains classifications of 3,927 galaxies from the COSMOS survey. 2008 . 2013) publications if using this data. Spirals" are galaxies with clearly The images come from co-added observations over dozens of epochs by SDSS, as compared to the shallower single-epoch images in Table 8. The Galaxy Zoo UI. We present this method as a powerful new approach to data exploration by providing a detailed understanding of the morphology and relationships of Radio Galaxy Zoo (RGZ) dataset image features which can be applied to new radio survey data. These are extinction-corrected but not, Stellar velocity dispersion (and error) measured using GANDALF, Table 1 - Normal-depth sample with new debiasing method, Table 1 contains all galaxies that were debiased with the method described in, Table 5 - Main sample, spectroscopic redshifts. (2010a) and Darg et al. If your science question benefits from having classifications from images comparable depth across an entire sample, we recommend using the. The properties These tables are also accessible via CasJobs. galaxies are blue in See Hoyle et al. Zoo Media. So go here to get classifying. Thanks for making Galaxy Zoo such a success! "Green peas" are compact galaxies with extremely high star-formation rates. 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. 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. The Zooniverse is the world’s largest and most popular platform for people-powered research. 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. colour, while most (2014) used GZ2 and preliminary GZ: Hubble data to study the evolution of the bar fraction in galaxies over cosmic timescales. This table gives classifications of galaxies which have spectra included in SDSS Data Release 7. 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. so this sample of red Data below is from Table 4 in Cardamone et al. September 11, 2015 — 0 Comments. Table 7 - Morphological classifications for galaxies from 2-epoch GOODS imaging.

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. This webpage allows anyone to download the resulting GZ classifications of nearly 900,000 galaxies in the project. This sample of merging galaxies is assembled from SDSS Galaxy Zoo 1 data. 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. With your help, we collected millions of classifications, and have done more and better science faster than we ever believed possible. This includes coordinates, photometry, size, and redshifts (where present). October 14, 2016 — 0 Comments.
