▪ Abstract The Local Group dwarf galaxies offer a unique window to the detailed properties
of the most common type of galaxy in the Universe. In this review, I update the census of …

Galactic structure surveys and the evolution of the Milky Way ADS Classic is now
deprecated. It will be completely retired in October 2019. This page will automatically …

We report the discovery of 6576 new spectroscopically confirmed white dwarf and subdwarf
stars in the Sloan Digital Sky Survey Data Release 12. We obtain T eff, log g and mass for …

We report the discovery of 9088 new spectroscopically confirmed white dwarfs and
subdwarfs in the Sloan Digital Sky Survey Data Release 10. We obtain T eff, log g and mass …

We derive new constraints on the mass of the Milky Way's dark matter halo, based on 2401
rigorously selected blue horizontal-branch halo stars from SDSS DR6. This sample enables …

We study numerical simulations of satellite galaxy disruption in a potential resembling that of
the Milky Way. Our goal is to assess whether a merger origin for the stellar halo would leave …

We have discovered a new Galactic satellite galaxy in the constellation of Sagittarius. The
Sagittarius dwarf galaxy galaxy subtends an angle of~ 10° on the sky, lies at a distance of 24 …

The role that minor mergers have played in the formation and structure of the Milky Way is
still an open question, about which there is much debate. We use numerical simulations to …

We develop an explicit model for the formation of the stellar halo from tidally disrupted,
accreted dwarf satellites in the cold dark matter (CDM) framework, focusing on predictions …
