The Sloan Digital Sky Survey has revealed an overdensity of stars ∼ 3 to the north-east of the Andromeda galaxy through a number excess of luminous red giant stars, which we have called Andromeda NE. With the data at hand, the distance to Andromeda NE is well enough determined to ascertain that these stars are bound within M31’s dark matter halo, rather than a physically unrelated projection. Andromeda NE has a g-band absolute magnitude of ∼ −11.6 and central surface brightness of ∼ 29mag… CONTINUE READING
