A statistical method for measuring the Galactic potential and testing gravity with cold tidal streams
Jorge Peñarrubia, Sergey E. Koposov, Matthew G. Walker
We introduce the Minimum Entropy Method, a simple statistical technique for constraining the Milky Way gravitational potential and simultaneously testing different gravity theories…
The coupling between the core/cusp and missing satellite problems
Jorge Peñarrubia, Andrew Pontzen, Matthew G. Walker +1
We calculate the energy that baryons must inject in cold dark matter (CDM) haloes in order to remove centrally-divergent DM cusps on scales relevant to observations of dwarf sphero…
The Star Formation & Chemical Evolution History of the Fornax Dwarf Spheroidal Galaxy
T. J. L. de Boer, E. Tolstoy, V. Hill +6
We present deep photometry in the B,V and I filters from CTIO/MOSAIC for about 270.000 stars in the Fornax dwarf Spheroidal galaxy, out to a radius of r_ell\sim0.8 degrees. By comb…
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…
