Broken degeneracies: the rotation curve and velocity anisotropy of the Milky Way halo
A. J. Deason, V. Belokurov, N. W. Evans +1
We use distant Blue Horizontal Branch stars with Galactocentric distances 16 < r/kpc < 48 as kinematic tracers of the Milky Way dark halo. We model the tracer density as an oblate,…
The cold veil of the Milky Way stellar halo
A. J. Deason, V. Belokurov, N. W. Evans +7
We build a sample of distant (D > 80 kpc) stellar halo stars with measured radial velocities. Faint () candidate blue horizontal branch (BHB) stars were selected using…
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…
The Star Formation History of Leo T from Hubble Space Telescope Imaging
Daniel R. Weisz, Daniel B. Zucker, Andrew E. Dolphin +9
We present the star formation history (SFH) of the faintest known star-forming galaxy, Leo T, based on imaging taken with the Hubble Space Telescope (HST) Wide Field Planetary Came…
A Tale Twice Told: The Luminosity Profiles of the Sagittarius Tails
Martin Niederste-Ostholt, Vasily Belokurov, Wyn Evans
The Sagittarius dwarf galaxy is the archetype of a tidally disrupting system. Both leading and trailing tails can be observed across at least 180 degrees of the sky and measurement…
