Dark-Ages Reionisation & Galaxy Formation Simulation XVI: The Thermal Memory of Reionisation
James E. Davies, Simon J. Mutch, Yuxiang Qin +3
Intergalactic medium temperature is a powerful probe of the epoch of reionisation, as information is retained long after reionisation itself. However, mean temperatures are highly…
Dark-ages Reionization and Galaxy Formation Simulation - XIV. Gas accretion, cooling and star formation in dwarf galaxies at high redshift
Yuxiang Qin, Alan R. Duffy, Simon J. Mutch +4
We study dwarf galaxy formation at high redshift () using a suite of high- resolution, cosmological hydrodynamic simulations and a semi-analytic model (SAM). We focus on gas…
KiDS-450 + 2dFLenS: Cosmological parameter constraints from weak gravitational lensing tomography and overlapping redshift-space galaxy clustering
Shahab Joudaki, Chris Blake, Andrew Johnson +19
We perform a combined analysis of cosmic shear tomography, galaxy-galaxy lensing tomography, and redshift-space multipole power spectra (monopole and quadrupole) using 450 deg…
Dark ages reionization & galaxy formation simulation XII: Bubbles at dawn
Paul M. Geil, Simon J. Mutch, Gregory B. Poole +3
Direct detection of regions of ionized hydrogen (HII) has been suggested as a promising probe of cosmic reionization. Observing the redshifted 21-cm signal of hydrogen from the epo…
Dark-ages Reionization and Galaxy Formation Simulation - X. The small contribution of quasars to reionization
Yuxiang Qin, Simon J. Mutch, Gregory B. Poole +6
Motivated by recent measurements of the number density of faint AGN at high redshift, we investigate the contribution of quasars to reionization by tracking the growth of central s…
Dark-ages Reionization & Galaxy Formation Simulation VIII. Suppressed growth of dark matter halos during the Epoch of Reionization
Yuxiang Qin, Alan R. Duffy, Simon J. Mutch +5
We investigate how the hydrostatic suppression of baryonic accretion affects the growth rate of dark matter halos during the Epoch of Reionization. By comparing halo properties in…
