H-alpha emission in local galaxies: star formation, time variability and the diffuse ionized gas
Sandro Tacchella, Aaron Smith, Rahul Kannan +6
The nebular recombination line H is widely used as a star-formation rate (SFR) indicator in the local and high-redshift Universe. We present a detailed H radiative transfer s…
The physics of Lyman-alpha escape from disc-like galaxies
Aaron Smith, Rahul Kannan, Sandro Tacchella +8
Hydrogen emission lines can provide extensive information about star-forming galaxies in both the local and high-redshift Universe. We present a detailed Lyman continuum (LyC), Lym…
Real and counterfeit cores: how feedback expands halos and disrupts tracers of inner gravitational potential in dwarf galaxies
Ethan D. Jahn, Laura V. Sales, Federico Marinacci +8
The tension between the diverging density profiles in Lambda Cold Dark Matter (CDM) simulations and the constant-density inner regions of observed galaxies is a long-standing ch…
Quiescent Ultra-diffuse galaxies in the field originating from backsplash orbits
José A. Benavides, Laura V. Sales, Mario. G. Abadi +8
Ultra-diffuse galaxies (UDGs) are the lowest-surface brightness galaxies known, with typical stellar masses of dwarf galaxies but sizes similar to larger galaxies like the Milky Wa…
Formation and evolution of young massive clusters in galaxy mergers: the SMUGGLE view
Hui Li, Mark Vogelsberger, Greg L. Bryan +3
Galaxy mergers are known to host abundant young massive cluster (YMC) populations, whose formation mechanism is still not well-understood. Here, we present a high-resolution galaxy…
Degeneracies Between Self-interacting Dark Matter and Supernova Feedback as cusp-core transformation mechanisms
Jan D. Burger, Jesús Zavala, Laura V. Sales +3
We present a suite of 16 high-resolution hydrodynamic simulations of an isolated dwarf galaxy (gaseous and stellar disk plus a stellar bulge) within an initially cuspy dark matter…
