Upper Limits on Planet-Induced GHz Radio Emission from Inactive M Dwarfs
Jackie Villadsen, Carter Russell, Luna Guerrero +9
Nearby short-period exoplanet systems may produce detectable stellar radio emission due to sub-Alfvénic star-planet interaction (SPI), but there are no confirmed cases yet. We tar…
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…
The dependence of the intracluster light fraction on galaxy cluster properties
Louisa Canepa, Sarah Brough, Mireia Montes +1
We use machine learning to measure the intracluster light (ICL) fractions of 177 galaxy groups and clusters identified from Hyper Suprime-Cam Subaru Strategic Program imaging to ex…
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…
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…
Measuring the intracluster light fraction with machine learning
Louisa Canepa, Sarah Brough, Francois Lanusse +2
The intracluster light (ICL) is an important tracer of a galaxy cluster's history and past interactions. However, only small samples have been studied to date due to its very low s…
