The filling factor of intergalactic metals at redshift z=3
C. M. Booth, Joop Schaye, J. D. Delgado +1
Observations of quasar absorption line systems reveal that the z=3 intergalactic medium (IGM) is polluted by heavy elements down to HI optical depths tau_HI<<10. What is not yet cl…
The rates and modes of gas accretion on to galaxies and their gaseous haloes
Freeke van de Voort, Joop Schaye, C. M. Booth +2
(Abridged) We study the rate at which gas accretes onto galaxies and haloes and investigate whether the accreted gas was shocked to high temperatures before reaching a galaxy. For…
The enrichment history of cosmic metals
Robert P. C. Wiersma, Joop Schaye, Claudio Dalla Vecchia +3
We use a suite of cosmological, hydrodynamical simulations to investigate the chemical enrichment history of the Universe. Specifically, we trace the origin of the metals back in t…
