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 (--…

Galaxy Zoo Bar Lengths: A Catalogue of Measurements from Hubble Space Telescope Images and the Evolution of Galactic Bar Structure at z < 1

Tenley Hutchinson-Smith, Brooke D. Simmons, Karen L. Masters +12

Understanding the role of galactic scale bars in disk galaxy evolution requires detailed measurements of bar properties across galaxies hosting bars at many redshifts. We present m…

The Role of Baryonic and Dark Matter in Bar Kinematics

Tobias Géron, Kai Zhu, Steph Campbell +3

Simulations predict that bars in galaxies should slow down over time. This is often attributed to the exchange of angular momentum between the bar and other regions of the galaxy,…

The complex relationships between AGN, bars and bulges

Izzy L. Garland, Henry Best, Lucy F. Fortson +9

Context. Via scaling relations, it is well-known that active galactic nuclei (AGN) and bulges are linked. This link was thought to be driven by mergers, but recent studies show tha…

Spatio-Spectroscopic Representation Learning using Unsupervised Convolutional Long-Short Term Memory Networks

Kameswara Bharadwaj Mantha, Lucy Fortson, Ramanakumar Sankar +8

Integral Field Spectroscopy (IFS) surveys offer a unique new landscape in which to learn in both spatial and spectroscopic dimensions and could help uncover previously unknown insi…

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…

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), A first look at the fraction of bars in massive galaxies at

Euclid Collaboration, M. Huertas-Company, M. Walmsley +336

Stellar bars are key structures in disc galaxies, driving angular momentum redistribution and influencing processes such as bulge growth and star formation. Quantifying the bar fra…

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…

COSMOS-Web: The emergence of the Hubble Sequence

M. Huertas-Company, M. Shuntov, Y. Dong +29

Leveraging the wide area coverage of the COSMOS-Web survey, we quantify the abundance of different morphological types from with unprecedented statistics and establish ro…

Galaxy Zoo: The interplay of quenching mechanisms in the group environment

R. J. Smethurst, C. J. Lintott, S. P. Bamford +5

Does the environment of a galaxy directly influence the quenching history of a galaxy? Here we investigate the detailed morphological structures and star formation histories of a s…

Galaxy Zoo: Evidence for rapid, recent quenching within a population of AGN host galaxies

R. J. Smethurst, C. J. Lintott, B. D. Simmons +8

We present a population study of the star formation history of 1244 Type 2 AGN host galaxies, compared to 6107 inactive galaxies. A Bayesian method is used to determine individual…

Galaxy Zoo: Passive Red Spirals

Karen L. Masters, Moein Mosleh, A. Kathy Romer +14

We study the spectroscopic properties and environments of red spiral galaxies found by the Galaxy Zoo project. By carefully selecting face-on, disk dominated spirals we construct a…
