Environmental Dependence of Self-Regulating Black-hole Feedback in Massive Galaxies
Deovrat Prasad, G. Mark Voit, Brian W. O'shea +1
In the universe's most massive galaxies, kinetic feedback from a central supermassive black hole appears to limit star formation. Abundant circumstantial evidence suggests that acc…
A Black-Hole Feedback Valve in Massive Galaxies
G. M. Voit, G. L. Bryan, D. Prasad +6
Star formation in the universe's most massive galaxies proceeds furiously early in time but then nearly ceases. Plenty of hot gas remains available but does not cool and condense i…
Figuring Out Gas & Galaxies In Enzo (FOGGIE). IV. The Stochasticity of Ram Pressure Stripping in Galactic Halos
Raymond C. Simons, Molly S. Peeples, Jason Tumlinson +9
We study ram pressure stripping in simulated Milky Way-like halos at z>=2 from the Figuring Out Gas & Galaxies In Enzo (FOGGIE) project. These simulations reach exquisite resolutio…
Cool-Core Cycles and Phoenix
Deovrat Prasad, Prateek Sharma, Arif Babul +2
Recent observations show that the star formation rate (SFR) in the {\it Phoenix} cluster's central galaxy is M yr. Even though {\it Phoenix} is a massive…
Circumgalactic Gas and the Precipitation Limit
G. M. Voit, A. Babul, Iu. Babyk +15
During the last decade, numerous and varied observations, along with increasingly sophisticated numerical simulations, have awakened astronomers to the central role the circumgalac…
