Tidal features as tracers of galaxy merger histories: the colours of tidal features in HSC-SSP
A. Desmons, S. Brough, L. Canepa +1
We measure the radial colour profiles of 32,000 galaxies drawn from the Hyper Suprime-Cam Subaru Strategic Program optical imaging survey, including 1415 exhibiting tid…
Investigating the imprints of tidal features on simulated galaxy outskirts in LSST-like mock observations
Aman Khalid, Sarah Brough, Garreth Martin +5
Tidal features provide signatures of recent galaxy mergers, offering insights into the role of mergers in galaxy evolution. The Vera C. Rubin Observatory's upcoming Legacy Survey o…
Tidal features around simulated groups and cluster galaxies: Enhancement and suppression of merger events through environment in LSST-like mock observations
Aman Khalid, Sarah Brough, Garreth Martin +5
Generally, merger likelihood increases in denser environments; however, the large relative velocities at the centres of dense clusters are expected to reduce the likelihood of merg…
Analysing the prevalence of tidal features in HSC-SSP using self-supervised representation learning
A. Desmons, S. Brough, F. Lanusse +2
We use a combination of self-supervised machine learning and visual classification to identify tidal features in a sample of 34,331 galaxies with stellar masses $\log_{10}(M_{*}/\r…
