How well can we measure the stellar mass of a galaxy: The impact of the assumed star formation history model in SED fitting
(IOP Publishing, 2020)
The primary method for inferring the stellar mass (M∗) of a galaxy is through spectral energy distribution (SED) modeling. However, the technique rests on assumptions such as the galaxy star formation history and dust ...
The impact of wind scalings on stellar growth and the baryon cycle in cosmological simulations
(Oxford University Press, 2020)
Many phenomenologically successful cosmological simulations employ kinetic winds to model galactic outflows. Yet systematic studies of how variations in kinetic wind scalings might alter observable galaxy properties are ...
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 ...
Lyman α absorption beyond the disc of simulated spiral galaxies
(Oxford University Press, 2020)
We present an analysis of the origin and properties of the circumgalactic medium (CGM) in a suite of 11 cosmological zoom simulations resembling present-day spiral galaxies. On average the galaxies retain about 50 per cent ...
