We report the spectroscopic analysis of 10 satellite galaxy candidates in the sphere of influence of the Sombrero galaxy (M104, NGC4594), based on data obtained with IFUM (integral field units for Magellan). Based on their newly observed recessional velocities, we confirm that nine of these candidates are satellite galaxies of M104, with one being a background dwarf galaxy. All 10 dwarfs have stellar masses 2x10(7) to 1x10(9)M(circle dot) and mean weighted metallicities -1.7
