The Size Evolution of Elliptical Galaxies
Lizhi Xie, Qi Guo, Andrew P. Cooper +3
Recent work has suggested that the amplitude of the size mass relation of massive early type galaxies evolves with redshift. Here we use a semi-analytical galaxy formation model to…
Galaxy formation in the Planck Cosmology - I. Matching the observed evolution of star formation rates, colours and stellar masses
Bruno Henriques, Simon White, Peter Thomas +5
We have updated the Munich galaxy formation model to the Planck first-year cosmology, while modifying the treatment of baryonic processes to reproduce recent data on the abundance…
Surface photometry of BCGs and intracluster stars in Lambda-CDM
Andrew P. Cooper, Liang Gao, Qi Guo +4
We simulate the phase-space distribution of stellar mass in 9 massive Lambda-CDM galaxy clusters by applying the semi-analytic particle tagging method of Cooper et al. to the Phoen…
The Local Void: for or against LCDM?
Lizhi Xie, Liang Gao, Qi Guo
The emptiness of the Local Void has been put forward as a serious challenge to the current standard paradigm of structure formation in LCDM. We use a high resolution cosmological N…
Herschel-ATLAS/GAMA:How does the far-IR luminosity function depend on galaxy group properties?
Qi Guo, Cedric Lacey, Peder Norberg +14
We use the Herschel ATLAS (H-ATLAS) Phase I data to study the conditional luminosity function of far-IR (250 um) selected galaxies in optically-selected galaxy groups from the GAMA…
