The similarity of the stellar mass fractions of galaxy groups and clusters
J. M. Budzynski, S. E. Koposov, I. G. McCarthy +1
We employ a large sample of 20171 optically-selected groups and clusters at 0.15 < z < 0.4 in the SDSS to investigate how the stacked stellar mass fraction varies across a wide ran…
Are group- and cluster-scale dark matter halos over-concentrated?
M. W. Auger, J. M. Budzynski, V. Belokurov +2
We investigate the relationship between the halo mass, M_200, and concentration, c, for a sample of 26 group- and cluster-scale strong gravitational lenses. In contrast with previo…
The radial distribution of galaxies in groups and clusters
J. M. Budzynski, S. Koposov, I. G. McCarthy +2
We present a new catalogue of 55,121 groups and clusters centred on Luminous Red Galaxies from SDSS DR7 in the redshift range 0.15<z<0.4. We provide halo mass estimates for each of…
Dusty MgII absorbers: population statistics, extinction curves and gamma-ray burst sightlines
J. M. Budzynski, P. C. Hewett
We present a new determination of the dust content and near-ultraviolet/optical extinction curves associated with a sample of ~8300 strong (equivalent width > 1A) Mg II absorbers,…
