A Dark Matter Hurricane: Measuring the S1 Stream with Dark Matter Detectors
Ciaran A. J. O'Hare, Christopher McCabe, N. Wyn Evans +2
The recently discovered S1 stream passes through the Solar neighbourhood on a low inclination, counter-rotating orbit. The progenitor of S1 is a dwarf galaxy with a total mass comp…
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 CASSOWARY spectroscopy survey: A new sample of gravitationally lensed galaxies in SDSS
Daniel P. Stark, Matthew Auger, Vasily Belokurov +7
Bright gravitationally lensed galaxies provide our most detailed view of galaxies at high redshift. Yet as a result of the small number of ultra-bright z~2 lensed systems with conf…
Constraining the dark energy equation of state with double source plane strong lenses
Thomas E. Collett, Matthew W. Auger, Vasily Belokurov +2
We investigate the possibility of constraining the dark energy equation of state by measuring the ratio of Einstein radii in a strong gravitational lens system with two source plan…
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…
