Stellar Substructure in the Halo and Outer Disk of M31
TL;DR: In this paper, the authors discuss evidence for spatial density and metallicity variations in the distribution of individual red giant branch stars in the halo and outer disk of the M31 galaxy.
Journal ArticleDOI
A tale of a tail: A tidally-disrupting ultra-diffuse galaxy in the M81 group
R. S. Zemaitis,Annette M. N. Ferguson,Sakurako Okamoto,Jean-Charles Cuillandre,Connor Stone,Nobuo Arimoto,Mike Irwin +6 more
TL;DR: In this article , the discovery of a giant tidal tail of stars associated with F8D1, the closest known example of an ultra-diffuse galaxy (UDG), was presented.
Journal ArticleDOI
Chemical Abundances of Metal-poor stars in Dwarf Galaxies
Kim A. Venn,Pascale Jablonka,Vanessa Hill,Else Starkenburg,B. Lemasle,Matthew Shetrone,Mike Irwin,John E. Norris,David Yong,Gerry Gilmore,Stephania Salvadori,Á. Skúladóttir,Eline Tolstoy +12 more
TL;DR: In this paper, the authors found that low-mass dwarf galaxies show a larger range in their chemical properties than those in the Milky Way halo, and that the slower star formation efficiency makes dwarf galaxies ideal systems for testing nucleosynthetic yields.
Journal ArticleDOI
The Canis Major Dwarf Galaxy
Geraint F. Lewis,Rodrigo A. Ibata,Mike Irwin,Nicolas F. Martin,Michele Bellazzini,Blair C. Conn +5 more
TL;DR: In this paper, the Canis Major satellite galaxy is found to lie just below the Galactic plane and appears to be on an equatorial orbit, suggesting that it represents a building block of the thick disk.

Adaptive optics imaging and integral field spectroscopy of APM 08279+5255: Evidence for gravitational lensing
Cedric Ledoux,Bertrand Theodore,Patrick Petitjean,Malcolm N. Bremer,Geraint F. Lewis,Rodrigo A. Ibata,Mike Irwin,Edward J. Totten +7 more
TL;DR: In this paper, the authors reported observations of the z = 3.87 broad ab-sorption line quasar APM 08279+5255 (Irwin et al. 1998) with the Adaptive Optics Bonnette (AOB) of the Canada-France- Hawaii Telescope.
