Star Formation and Environmental Quenching of GEEC2 Group Galaxies at z~1
Angus Mok, Michael L. Balogh, Sean L. McGee +7
We present new analysis from the GEEC2 spectroscopic survey of galaxy groups at . Our previous work revealed an intermediate population between the star-forming and quiesc…
The impact of angular momentum on black hole accretion rates in simulations of galaxy formation
Y. M. Rosas-Guevara, R. G. Bower, J. Schaye +7
Feedback from energy liberated by gas accretion onto black holes (BHs) is an attractive mechanism to explain the exponential cut-off at the massive end of the galaxy stellar mass f…
A fundamental metallicity relation for galaxies at z = 0.84 - 1.47 from HiZELS
John P. Stott, David Sobral, Richard Bower +6
We obtained Subaru FMOS observations of Halpha emitting galaxies selected from the HiZELS narrow-band survey, to investigate the relationship between stellar mass, metallicity and…
Do group dynamics play a role in the evolution of member galaxies?
Annie Hou, Laura C. Parker, Michael L. Balogh +8
We examine galaxy groups from the present epoch to z = 1 to explore the impact of group dynamics on galaxy evolution. We use group catalagues from the Sloan Digital Sky Survey (SDS…
The Hot and Energetic Universe: A White Paper presenting the science theme motivating the Athena+ mission
Kirpal Nandra, Didier Barret, Xavier Barcons +237
This White Paper, submitted to the recent ESA call for science themes to define its future large missions, advocates the need for a transformational leap in our understanding of tw…
Efficient satellite quenching at z~1 from the GEEC2 spectroscopic survey of galaxy groups
Angus Mok, Michael L. Balogh, Sean L. McGee +9
We present deep GMOS-S spectroscopy for 11 galaxy groups at 0.8<z<1.0, for galaxies with r_{AB}<24.75. Our sample is highly complete (>66%) for eight of the eleven groups. Using an…
