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…

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…

Euclid Quick Data Release (Q1): First visual morphology catalogue

Euclid Collaboration, M. Walmsley, M. Huertas-Company +352

We present a detailed visual morphology catalogue for Euclid's Quick Release 1 (Q1). Our catalogue includes galaxy features such as bars, spiral arms, and ongoing mergers, for the…

Euclid Quick Data Release (Q1). Photometric redshifts and physical properties of galaxies through the PHZ processing function

Euclid Collaboration, M. Tucci, S. Paltani +344

The ESA Euclid mission will measure the photometric redshifts of billions of galaxies in order to provide an accurate 3D view of the Universe at optical and near-infrared wavelengt…
