The dwarf spheroidal galaxy Andromeda V is discovered as a very faint satellite of M31, adding to evidence for a rich system of low-luminosity companions.
Spitzer observations reveal an inner dust ring whose geometry supports a past near head-on passage of the companion galaxy M32 through Andromeda's disk.
A deep Chandra analysis catalogues hundreds of X-ray point sources across M31, improving inventories of X-ray binaries, remnants and background objects.
Project AMIGA uses background quasars to map ionized gas around M31 in greater detail, showing a layered halo extending far beyond the visible stellar disk.
