At the meeting we spent time analyzing these classifications to consider\/discuss changes needed for a larger launch. We also worked on papers using the CEERs based classifications, and two finished scientific papers came out of this work:\u00a0<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400\"><a href=\"https:\/\/doi.org\/10.1093\/mnras\/staf506\"><span style=\"font-weight: 400\">Smethurst et al. 2025<\/span><\/a><span style=\"font-weight: 400\">:\u00a0 &#8220;Galaxy Zoo JWST: up to 75 per\u2009cent of discs are featureless at 3 &lt; z &lt; 7&#8221; where we investigate an interesting sample of galaxies which are rotating discs (based on their surface brightness profiles), but show no visible features (spirals, bars etc) despite the images having the necessary resolution and depth to see them.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Geron et al. submitted (<\/span><a href=\"https:\/\/ui.adsabs.harvard.edu\/abs\/2025arXiv250501421G\/abstract\"><span style=\"font-weight: 400\">available on arxiv<\/span><\/a><span style=\"font-weight: 400\">): &#8220;Galaxy Zoo CEERS: Bar fractions up to z~4.0\u201d\u00a0<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400\">We also continue to work on\u00a0<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">\u201cGZ: CEERS &#8211; How well does the Traditional Galaxy Zoo Classification Tree Work at High Redshift\u201d, a paper intended to be the data release for the CEERS classifications and look at statistics of what fraction of the galaxy population at these redshifts fit on the classification tree.\u00a0<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400\">At our second meeting, we focused on collecting images from other JWST surveys. Realising that the COSMOSweb survey contained 80% of the remaining images of galaxies classifiable by Galaxy Zoo, we focused on generating colour image cutouts, and deciding on target selection of ~300,000 galaxies in that survey. Following the work done at this meeting, a \u201cGalaxy Zoo: JWST\u201d relaunch happened April 29th 2025 with some press from NASA (as we join the &#8220;<a href=\"https:\/\/science.nasa.gov\/citizen-science\/\">NASA Citizen Science<\/a>&#8221; family <\/span><span style=\"font-weight: 400\">) and the <a href=\"http:\/\/www.zooniverse.org\">Zooniverse<\/a>. At the time of writing (Jun 2025) is anticipated that it will take roughly a year for classifications to be collected for this set of images.\u00a0<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The Galaxy Zoo science team proposed an International Team project with the goal of collecting, processing and making available to the community Galaxy Zoo\u00a0classifications for public, multi-filter JWST NIRCam imaging of resolved galaxies.
