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…
The redshift dependence of the structure of massive LCDM halos
Liang Gao, Julio F. Navarro, Shaun Cole +5
(Abridged) We use two very large cosmological simulations to study how the density profiles of relaxed LCDM dark halos depend on redshift and on halo mass. We confirm that these pr…
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,…
The Nature of CO Emission From z~6 Quasars
Desika Narayanan, Yuexing Li, Thomas J. Cox +9
We investigate the nature of CO emission from z~6 quasars by combining non-LTE radiative transfer calculations with merger-driven models of z~6 quasar formation that arise naturall…
Assembly bias in the clustering of dark matter haloes
Liang Gao, Simon D. M. White
We use a very large simulation of structure growth in a LCDM universe -- the Millennium Simulation -- to study assembly bias, the fact that the large-scale clustering of haloes of…
Formation of z ~ 6 quasars from hierarchical galaxy mergers
Yuexing Li, Lars Hernquist, Brant Robertson +8
The discovery of luminous quasars at redshift z ~ 6 indicates the presence of supermassive black holes (SMBHs) of mass ~10^9 Msun when the Universe was less than one billion years…
