Understanding the regulation of star formation within TNG100 galaxies on kpc-scales using machine learning I: Global versus local
Bryanne McDonough, Sathvika S. Iyengar, Ansa Brew-Smith +2
We apply Random Forest and XGBoost machine learning algorithms to determine which galaxy properties most effectively predict star formation and quenching in simulated galaxies. Usi…
Beyond the Merger-Quasar-Quench Paradigm I: Mergers are neither necessary nor sufficient to quench central galaxies in IllustrisTNG
Camilo A. Casimiro, Asa F. L. Bluck, Paul Goubert +2
The cessation of star formation in galaxies, known as 'quenching', is a complex, multi-scale process which has been theorized to be linked to galaxy mergers. In this paper, we inve…
The ALMaQUEST Survey XVII: Unveiling Multiple Quenching Pathways in Green Valley Galaxies via Molecular Gas and Quenching Timescale Analyses
Lihwai Lin, Po-Feng Wu, Mallory D. Thorp +6
Statistically, green valley (GV) galaxies exhibit lower molecular gas fractions () and reduced star formation efficiency (SFE) compared to star-forming galaxies. However,…
Environmental vs. intrinsic quenching at cosmic noon: Predictions from cosmological hydrodynamical simulations for VLT-MOONRISE
Paul H. Goubert, Asa F. L. Bluck, Joanna M. Piotrowska +5
We present an investigation into the quenching of simulated galaxies across cosmic time, honing in on the role played by both intrinsic and environmental mechanisms at different ep…
