SIMBA: the average properties of the circumgalactic medium of 2 ≤ z ≤ 3 quasars are determined primarily by stellar feedback
(Oxford University Press, 2020-10-05)
We use the SIMBA cosmological hydrodynamic simulation suite to explore the impact of feedback on the circumgalactic medium
(CGM) and intergalactic medium (IGM) around 2 ≤ z ≤ 3 quasars. We identify quasars in SIMBA as the ...
The COS-Halos survey: Rationale, design and a census of circumgalactic neutral hydrogen
(IOP Publishing, 2013)
We present the design and methods of the COS-Halos survey, a systematic investigation of the gaseous halos of
44 z = 0.15–0.35 galaxies using background QSOs observed with the Cosmic Origins Spectrograph aboard the
Hubble ...
The cosmic evolution of the IMF under the Jeans conjecture with implications for massive galaxies
(Oxford University Press, 2013)
We examine the cosmic evolution of a stellar initial mass function (IMF) in galaxies that varies
with the Jeans mass in the interstellar medium, paying particular attention to the K-band stellar
mass-to-light ratio (M/LK) ...
The host haloes of O I absorbers in the reionization epoch
(Oxford University Press, 2013)
We use a radiation hydrodynamic simulation of the hydrogen reionization epoch to study
OI absorbers at z ∼ 6. The intergalactic medium (IGM) is reionized before it is enriched;
hence, OI absorption originates within dark ...
The neutral hydrogen content of galaxies in cosmological hydrodynamic simulations
(Oxford University Press, 2013)
We examine the global HI properties of galaxies in quarter billion particle cosmological
simulations using GADGET-2, focusing on howgalactic outflows impactHI content.We consider
four outflow models, including a new one ...
