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…
XMM-Newton Conclusively Identifies an Active Galactic Nucleus in a Green Pea Galaxy
Peter G. Boorman, Jiří Svoboda, Daniel Stern +23
Green Pea galaxies are a class of compact, low-mass, low-metallicity star-forming galaxies in the relatively local universe. They are believed to be analogues of high-redshift gala…
Zooming In On The Multi-Phase Structure of Magnetically-Dominated Quasar Disks: Radiation From Torus to ISCO Across Accretion Rates
Philip F. Hopkins, Kung-Yi Su, Norman Murray +12
Recent radiation-thermochemical-magnetohydrodynamic simulations resolved formation of quasar accretion disks from cosmological scales down to ~300 gravitational radii , argu…
Effects of galactic environment on size and dark matter content in low-mass galaxies
Francisco J. Mercado, Jorge Moreno, Robert Feldmann +8
We utilize the cosmological volume simulation, FIREbox, to investigate how a galaxy's environment influences its size and dark matter content. Our study focuses on approximately 1,…
Black hole spin evolution across cosmic time from the NewHorizon simulation
Ricarda S. Beckmann, Yohan Dubois, Marta Volonteri +8
Astrophysical black holes (BHs) have two fundamental properties: mass and spin. While the mass-evolution of BHs has been extensively studied, much less work has been done on predic…
