Massloss of galaxies due to a UV-background
Takashi Okamoto, Liang Gao, Tom Theuns
We perform cosmological hydrodynamic simulations to determine to what extent galaxies lose their gas due to photoheating from an ionizing background. We find that the characteristi…
Lighting the Universe with filaments
Liang Gao, Tom Theuns
The first stars in the Universe form when chemically pristine gas heats as it falls into dark matter potential wells, cools radiatively due to the formation of molecular hydrogen,…
Molecular cloud regulated star formation in galaxies
C. M. Booth, T. Theuns, T. Okamoto
We describe a numerical implementation of star formation in disk galaxies, in which the conversion of cooling gas to stars in the multiphase interstellar medium is governed by the…
Modelling Shock Heating in Cluster Mergers: I. Moving Beyond the Spherical Accretion Model
Ian G. McCarthy, Richard G. Bower, Michael L. Balogh +6
(Abridged) The thermal history of the intracluster medium (ICM) is complex. Heat input from cluster mergers, AGN, and galaxy winds offsets and may even halt the cooling of the ICM.…
Detecting HeliumII reionization from a sudden injection of entropy in the intergalactic medium
Tom Theuns, Saleem Zaroubi, Tae-Sun Kim
The temperature of the low-density intergalactic medium is set by the balance between adiabatic cooling resulting from the expansion of the universe, and photo-heating by the UV-ba…
Constraining reionization using the thermal history of the baryons
Joop Schaye, Tom Theuns, Michael Rauch +2
The thermal evolution of the intergalactic medium (IGM) depends on the reionization history of the universe. Numerical simulations indicate that the low density IGM, which is respo…
