Euclid: Quick Data Release (Q1) -- Exploring the detailed visual morphology of galaxies in clusters

P. Mas-Buitrago, S. Kruk, D. O'Ryan +167

Galaxy clusters provide unique laboratories for studying environmental effects on galaxy evolution. The morphology--density (--) and morphology--cluster-centric radius (--…

High-Redshift Gravitational Lens Discoveries in JWST NIRCam Using AnomalyMatch

Julia Dima, David O'Ryan, Sandor Kruk +2

Context. Strong gravitational lenses provide a unique tool to probe cosmology and astrophysics at high redshift, offering constraints on the mass distribution of background source…

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…

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…

Timescales for the Effects of Interactions on Galaxy Properties and SMBH Growth

D. O'Ryan, B. D. Simmons, A. L. Faisst +15

Galaxy interaction and merging have clear effects on the systems involved. We find an increase in the star formation rate (SFR), potential ignition of active galactic nuclei (AGN)…

Galaxy Zoo JWST: Up to 75% of discs are featureless at

R. J. Smethurst, B. D. Simmons, T. Géron +21

We have not yet observed the epoch at which disc galaxies emerge in the Universe. While high- measurements of large-scale features such as bars and spiral arms trace the evoluti…
