Cosmic Rays or Turbulence can Suppress Cooling Flows (Where Thermal Heating or Momentum Injection Fail)
Kung-Yi Su, Philip F. Hopkins, Christopher C. Hayward +6
The quenching `maintenance' and `cooling flow' problems are important from the Milky Way through massive cluster elliptical galaxies. Previous work has shown that some source of en…
Radiative Stellar Feedback in Galaxy Formation: Methods and Physics
Philip F. Hopkins, Michael Y. Grudic, Andrew R. Wetzel +5
Radiative feedback (RFB) from stars plays a key role in galaxies, but remains poorly-understood. We explore this using high-resolution, multi-frequency radiation-hydrodynamics (RHD…
The physics of Lyman-alpha escape from high-redshift galaxies
Aaron Smith, Xiangcheng Ma, Volker Bromm +4
Lyman-alpha (Lyα) photons from ionizing sources and cooling radiation undergo a complex resonant scattering process that generates unique spectral signatures in high-redshift galax…
The failure of stellar feedback, magnetic fields, conduction, and morphological quenching in maintaining red galaxies
Kung-Yi Su, Philip F. Hopkins, Christopher C. Hayward +5
The quenching "maintenance'" and related "cooling flow" problems are important in galaxies from Milky Way mass through clusters. We investigate this in halos with masses $\sim 10^{…
A Closer look at Bursty Star Formation with and Distributions
Najmeh Emami, Brian Siana, Daniel R. Weisz +3
We investigate the bursty star formation histories (SFHs) of dwarf galaxies using the distribution of log() of 185 local galaxies. We expand on the work of Weisz et…
