Crater 2: An Extremely Cold Dark Matter Halo
Nelson Caldwell, Matthew G. Walker, Mario Mateo +6
We present results from MMT/Hectochelle spectroscopy of red giant candidate stars along the line of sight to the recently-discovered Galactic satellite Crater 2. Modelling the join…
Near-Field cosmology with RR Lyrae variable stars: A first view of substructure in the southern sky
S. Duffau, A. K. Vivas, C. Navarrete +7
We present an update of a spectroscopic follow-up survey at low-resolution of a large number of RR Lyrae halo overdensity candidates found in the southern sky. The substructure can…
At the survey limits: discovery of the Aquarius 2 dwarf galaxy in the VST ATLAS and the SDSS data
G. Torrealba, S. E. Koposov, V. Belokurov +7
We announce the discovery of the Aquarius~2 dwarf galaxy, a new distant satellite of the Milky Way, detected on the fringes of the VST ATLAS and the SDSS surveys. The object was or…
The feeble giant. Discovery of a large and diffuse Milky Way dwarf galaxy in the constellation of Crater
G. Torrealba, S. E. Koposov, V. Belokurov +1
We announce the discovery of the Crater 2 dwarf galaxy, identified in imaging data of the VST ATLAS survey. Given its half-light radius of ~1100 pc, Crater 2 is the fourth largest…
