nIFTy galaxy cluster simulations – V. Investigation of the cluster infall region
(Oxford University Press, 2016)
We examine the properties of the galaxies and dark matter haloes residing in the cluster
infall region surrounding the simulated cold dark matter galaxy cluster studied by Elahi
et al. at z = 0. The 1.1 × 1015 h−1M ...
MUFASA: The strength and evolution of galaxy conformity in various tracers
(Oxford University Press, 2017)
We investigate galaxy conformity using the Mufasa cosmological hydrodynamical
simulation. We show a bimodal distribution in galaxy colour with radius, albeit
with too many low-mass quenched satellite galaxies compared ...
Properties of submillimeter galaxies in the CANDELS GOODS-south field
(American Physical Society, 2014)
We derive physical properties of 10 submillimeter galaxies located in the CANDELS coverage of the GOODS-S field. The galaxies were first identified as submillimeter sources with the LABOCA bolometer and subsequently targeted ...
A deep search for faint galaxies associated with very low-redshift C iv absorbers: A case with cold-accretion characteristics
(The American Astronomical Society, 2013)
Studies of QSO absorber–galaxy connections are often hindered by inadequate information on whether faint/dwarf
galaxies are located near the QSO sight lines. To investigate the contribution of faint galaxies to QSO ...
Mufasa: The assembly of the red sequence
(Oxford University Press, 2017)
We examine the growth and evolution of quenched galaxies in the Mufasa cosmo-
logical hydrodynamic simulations that include an evolving halo mass-based quench-
ing prescription, with galaxy colours computed accounting ...
Optical-faint, far-infrared-bright Herschel sources in the CANDELS fields: Ultra-luminous infrared galaxies at z > 1 and the effect of source blending
(American Astronomical Society, 2014)
The Herschel very wide-field surveys have charted hundreds of square degrees in multiple far-IR
(FIR) bands. While the Sloan Digital Sky Survey (SDSS) is currently the best resource for optical
counterpart identifications ...
Black hole - galaxy correlations without self-regulation
(American Astronomical Society, 2013)
Recent models of black hole growth in a cosmological context have forwarded a paradigm in which the growth
is self-regulated by feedback from the black hole itself. Here we use cosmological zoom simulations of galaxy
formation ...
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 slow flow model of dust eflux in local star-forming galaxies
(Oxford University Press, 2013)
We develop a dust efflux model of radiation pressure acting on dust grains which
successfully reproduces the relation between stellar mass, dust opacity and star forma-
tion rate observed in local star-forming galaxies. ...
