We report the discovery of Andromeda X, a new dwarf spheroidal satellite of M31, based on stellar photometry from the Sloan Digital Sky Survey. Using follow-up imaging data we have estimated its distance and other physical properties. We find that Andromeda X has a dereddened central surface brightness of μV, 0 ~ 26.7 mag arcsec-2 and a total apparent magnitude of Vtot ~ 16.1, which at the derived distance modulus, (m - M)0 ~ 24.12-24.34, yields an absolute magnitude of MV ~ -8.1 ± 0.5; these…

Andromeda XVII: A New Low-Luminosity Satellite of M31
We report the discovery of a new dwarf spheroidal galaxy near M31 on the basis of INT/WFC imaging. The system, Andromeda XVII (And XVII), is located at a projected radius of 44 kpc from M31, has a
ANDROMEDA XXIX: A NEW DWARF SPHEROIDAL GALAXY 200 kpc FROM ANDROMEDA
We report the discovery of a new dwarf galaxy, Andromeda XXIX (And XXIX), using data from the recently released Sloan Digital Sky Survey Data Release 8, and confirmed by Gemini North telescope
Discovery of Andromeda XIV: A Dwarf Spheroidal Dynamical Rogue in the Local Group?
In the course of our survey of the outer halo of the Andromeda galaxy we have discovered a remote, possible satellite of that system at a projected 162 kpc (11.7°) radius. The fairly elongated (0.31
Dwarf spheroidal satellites of M31. I. Variable stars and stellar populations in Andromeda XIX
We present B, V time-series photometry of Andromeda XIX (And XIX), the most extended (half-light radius of 6.'2) of Andromeda's dwarf spheroidal companions, which we observed with the Large Binocular
Andromeda XXVIII: A Dwarf Galaxy More Than 350 kpc from Andromeda
We report the discovery of a new dwarf galaxy, Andromeda XXVIII, using data from the recently released Sloan Digital Sky Survey Data Release 8. The galaxy is a likely satellite of Andromeda, and, at
A KINEMATIC STUDY OF THE ANDROMEDA DWARF SPHEROIDAL SYSTEM
We present a homogeneous kinematic analysis of red giant branch stars within 18 of the 28 Andromeda dwarf spheroidal (dSph) galaxies, obtained using the Keck I/LRIS and Keck II/DEIMOS spectrographs.
A DEEP PHOTOMETRIC LOOK AT TWO OF ANDROMEDA'S DWARF SPHEROIDALS: X AND XVII
We use deep wide-field photometry from the Large Binocular Camera to study the stellar and structural properties of the recently discovered Andromeda X and Andromeda XVII (And X and And XVII) dwarf
A rogues gallery of Andromeda’s dwarf galaxies – II. Precise distances to 17 faint satellites
We present new horizontal branch (HB) distance measurements to 17 of the faintest known M31 satellites (−6 ≲ MV ≲ −13) based on deep Hubble Space Telescope (HST) imaging. The colour–magnitude
A Keck/DEIMOS spectroscopic survey of faint Galactic satellites: searching for the least massive dwarf galaxies
We present the results of a spectroscopic survey of the recently discovered faint Milky Way satellites Bootes, Ursa Major I, Ursa Major II and Willman 1 (Will). Using the DEep Imaging Multi-Object
A Trio of New Local Group Galaxies with Extreme Properties
TLDR
The discovery of three new dwarf galaxies in the Local Group are reported on, which indicate that the full parameter space occupied by dwarf galaxies is not yet sampled, although this is an essential prerequisite for successfully and consistently linking these systems to the predicted cosmological dark matter substructure.
