The effect of galaxy interactions on star formation rates in the COLIBRE simulations
Quinten W. E. van Zegveld, Evgenii Chaikin, Joop Schaye +8
Observations and theory indicate that galaxy interactions enhance star formation rates (SFRs). However, the degree of enhancement and its dependence on the properties of the intera…
Galaxy Mergers in UNIONS -- II: Predicting Timescales in the Post-Merger Regime
Leonardo Ferreira, Sara L. Ellison, David R. Patton +3
Galaxy mergers are critical events that influence galaxy evolution by driving processes such as enhanced star formation, quenching, and active galactic nucleus (AGN) activity. Howe…
Interacting galaxies in the IllustrisTNG simulations - IX: Mini mergers trigger AGN in cosmological simulations
Shoshannah Byrne-Mamahit, Sara L. Ellison, David R. Patton +3
Galaxy mergers are transformative events that can cause gaseous inflows capable of triggering active galactic nuclei (AGN). Previous studies of AGN in simulations have mainly focus…
UNIONS: The Ultraviolet Near-Infrared Optical Northern Survey
Stephen Gwyn, Alan W. McConnachie, Jean-Charles Cuillandre +86
The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is a "collaboration of collaborations" that is using the Canada-France-Hawai'i Telescope, the Pan-STARRS telescopes,…
Galaxy evolution in the post-merger regime. III -- The triggering of active galactic nuclei peaks immediately after coalescence
Sara L. Ellison, Leonardo Ferreira, Robert Bickley +6
Galaxy mergers have been shown to trigger AGN in the nearby universe, but the timescale over which this process happens remains unconstrained. The Multi-Model Merger Identifier (MU…
Interacting galaxies in the IllustrisTNG simulations -- VIII: Pericentric star formation rate enhancements are driven both by increased fuelling and efficiency
Lawrence Faria, David R. Patton, Stéphane Courteau +2
Using the TNG100-1 cosmological simulations, we explore how galaxy properties, such as specific star formation rate (), gas fraction ($\rm f_{gas} \,= \, M_{\rm H…
