Galaxy mergers drive enhancements in ionization states
A. Le Reste, K. B. Mantha
Recent studies have suggested that galaxy mergers may help drive the escape of ionizing photons from galaxies. However, the ionization properties of merging galaxies have not yet b…
Specific Star Formation Rate Enhancement across the Galaxy Merger Sequence: Insights from Citizen Science Classifications
Jacob Lee, Alexandra Le Reste, Claudia Scarlata +1
We present an analysis of specific star formation rates (sSFR) across the galaxy merger sequence using visual classifications from the Zooniverse citizen science project "Cosmic Di…
Characterization of Residual Morphological Substructure Using Supervised and Unsupervised Deep Learning
Kameswara Bharadwaj Mantha, Daniel H. McIntosh, Cody Ciaschi +9
Automated characterization of galactic substructure is an essential step in understanding the transformative physical processes driving galaxy evolution. In this study, we investig…
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…
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…
