Galaxy Zoo Evo: 1 million human-annotated images of galaxies
Mike Walmsley, Steven Bamford, Hugh Dickinson +17
We introduce Galaxy Zoo Evo, a labeled dataset for building and evaluating foundation models on images of galaxies. GZ Evo includes 104M crowdsourced labels for 823k images from fo…
Strong Bars, Strong Inflow: The Effect of Bar Strength on Gas Inflow
Maelle Magnan, Tobias Geron, Izzy L. Garland +5
Stellar bars are elongated structures in disk galaxies that can torque and funnel gas inward, influencing galaxy evolution. While strong bars are known to induce rapid inflow, the…
Bars in low-density environments rotate faster than bars in dense regions
Natalia Puczek, Tobias Géron, Rebecca J. Smethurst +1
Does the environment of a galaxy directly influence the kinematics of its bar? We present observational evidence that bars in high-density environments exhibit significantly slower…
Galaxy Zoo: Cosmic Dawn -- morphological classifications for over 41,000 galaxies in the Euclid Deep Field North from the Hawaii Two-0 Cosmic Dawn survey
James Pearson, Hugh Dickinson, Stephen Serjeant +22
We present morphological classifications of over 41,000 galaxies out to across six square degrees of the Euclid Deep Field North (EDFN) from the Hawaii Twenty…
Galaxy Zoo CEERS: Bar fractions up to z~4.0
Tobias Géron, R. J. Smethurst, Hugh Dickinson +22
We study the evolution of the bar fraction in disc galaxies between using multi-band coloured images from JWST CEERS. These images were classified by citizen scient…
