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…
Cutana: A High-Performance Tool for Astronomical Image Cutout Generation at Petabyte Scale
Pablo Gómez, Laslo Erik Ruhberg, Kristin Anett Remmelgas +1
The Euclid Quick Data Release 1 (Q1) encompasses 30 million sources across 63.1 square degrees, marking the beginning of petabyte-scale data delivery through Data Release 1 (DR1) a…
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…
AnomalyMatch: Discovering Rare Objects of Interest with Semi-supervised and Active Learning
Pablo Gómez, Laslo E. Ruhberg, Maria Teresa Nardone +1
Anomaly detection in large datasets is essential in astronomy and computer vision. However, due to a scarcity of labelled data, it is often infeasible to apply supervised methods t…
Identifying Astrophysical Anomalies in 99.6 Million Cutouts from the Hubble Legacy Archive Using AnomalyMatch
David O'Ryan, Pablo Gómez
Astronomical archives contain vast quantities of unexplored data that potentially harbour rare and scientifically valuable cosmic phenomena. We leverage new semi-supervised methods…
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…
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…
Euclid Quick Data Release (Q1). First Euclid statistical study of galaxy mergers and their connection to active galactic nuclei
Euclid Collaboration, A. La Marca, L. Wang +334
Galaxy major mergers are a key pathway to trigger AGN. We present the first detection of major mergers in the Euclid Deep Fields and analyse their connection with AGN. We construct…
