Precession of the Sagittarius stream
V. Belokurov, S. E. Koposov, N. W. Evans +9
Using a variety of stellar tracers -- blue horizontal branch stars, main-sequence turn-off stars and red giants -- we follow the path of the Sagittarius (Sgr) stream across the sky…
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…
The Sagittarius Streams in the Southern Galactic Hemisphere
Sergey E. Koposov, V. Belokurov, N. W. Evans +12
The structure of the Sagittarius stream in the Southern Galactic hemisphere is analysed with the Sloan Digital Sky Survey Data Release 8. Parallel to the Sagittarius tidal track, b…
Detection of intrinsic cluster alignments to 100 Mpc/h in the SDSS
A. Smargon, R. Mandelbaum, N. Bahcall +1
We measure the large-scale intrinsic alignments of galaxy clusters in the Sloan Digital Sky Survey (SDSS) using subsets of two cluster catalogues: 6625 clusters with 0.1<z<0.3 from…
Was the Progenitor of the Sagittarius Stream a Disc Galaxy?
Jorge Penarrubia, Vasily Belokurov, N. Wyn Evans +5
We use N-body simulations to explore the possibility that the Sagittarius (Sgr) dwarf galaxy was originally a late-type, rotating disc galaxy, rather than a non-rotating, pressure-…
Alignment of Brightest Cluster Galaxies with their Host Clusters
Martin Niederste-Ostholt, Michael A. Strauss, Feng Dong +2
We examine the alignment between Brightest Cluster Galaxies (BCGs) and their host clusters in a sample of 7031 clusters with 0.08<z<0.44 found using a matched-filter algorithm and…
