Description

We present the results of a thorough study of the nucleus of the Sgr dwarf spheroidal galaxy (Sgr dSph) and of the bright globular cluster M54 (NGC 6715) that resides within the same nucleus (Sgr,N). We have obtained accurate radial velocities and metallicity estimates for 1152 candidate red giant branch stars of Sgr and M54 lying within 9′ from the center of the galaxy, from Keck/DEIMOS and VLT/FLAMES spectra of the infrared Ca II triplet. Using both velocity and metallicity information we...[Show more]
