A lack of evolution in the very bright end of the galaxy luminosity function from z 8 to 10
(Oxford University Press, 2020)
ABSTRACT
We utilize deep near-infrared survey data from the UltraVISTA fourth data release (DR4) and the VIDEO survey, in combination with overlapping optical and Spitzer data, to search for bright star-forming galaxies ...
The rest-frame UV luminosity function at z 4: A significant contribution of AGNs to the bright end of the galaxy population
(Oxford University Press, 2020)
We measure the rest-frame ultraviolet (UV) luminosity function (LF) at z ∼ 4 self-consistently over a wide range in absolute magnitude (−27 ≲ MUV ≲ −20). The LF is measured with 46 904 sources selected using a photometric ...
Testing galaxy formation simulations with damped Lyman-α abundance and metallicity evolution
(Oxford University Press, 2020)
We examine the properties of damped Lyman-α absorbers (DLAs) emerging from a single set of cosmological initial conditions in two state-of-the-art cosmological hydrodynamic simulations: SIMBA and TECHNICOLOR DAWN. The ...
NIFTY galaxy cluster simulations – VI. The dynamical imprint of substructure on gaseous cluster outskirts
(Oxford University Press, 2019)
Galaxy cluster outskirts mark the transition region from the mildly non-linear cosmic web to the highly non-linear, virialized, cluster interior. It is in this transition region that the intracluster medium (ICM) begins ...
Cosmological baryon transfer in the SIMBA simulations
(Oxford University Press, 2019)
We present a framework for characterizing the large-scale movement of baryons relative to dark matter in cosmological simulations, requiring only the initial conditions and final state of the simulation. This is performed ...
The impact of quenching on galaxy profiles in the SIMBA simulation
(Oxford University Press, 2020)
We study specific star formation rate (sSFR) and gas profiles of star-forming (SF) and green valley (GV) galaxies in the SIMBA cosmological hydrodynamic simulation. SF galaxy half-light radii (Rhalf) at z = 0 and their ...
The baryonic Tully–Fisher relation in the SIMBA simulation
(Oxford University Press, 2020)
We investigate the Baryonic Tully–Fisher relation (BTFR) in the (100h−1Mpc)3SIMBA hydrodynamical galaxy formation simulation together with a higher resolution (25h−1Mpc)3SIMBA run, for over 10 000 disc-dominated, H I-rich ...
Photometric properties of reionization-epoch galaxies in the SIMBA simulations
(Oxford University Press, 2020)
We study the photometric properties and sizes of the reionization-epoch galaxies in high-resolution SIMBA cosmological hydrodynamical simulations with box sizes of [25,50]h−1Mpc. Assuming various attenuation laws, we ...
An ALMA survey of the brightest sub-millimetre sources in the SCUBA-2–COSMOS field
(Oxford University Press, 2020)
ABSTRACT
We present an ALMA study of the ∼180 brightest sources in the SCUBA-2 850-μm map of the COSMOS field from the S2COSMOS survey, as a pilot study for AS2COSMOS – a full survey of the ∼1000 sources in this field. ...
The redshift evolution of the baryonic Tully-Fisher relation in SIMBA
(Oxford university press, 2021)
The baryonic Tully–Fisher relation (BTFR) is an important tool for constraining galaxy evolution models. As 21-cm HI emission
studies have been largely restricted to low redshifts, the redshift evolution of the BTFR is ...
