A PAndAS view of M31 dwarf elliptical satellites: NGC147 and NGC185
D. Crnojević, A. M. N. Ferguson, M. J. Irwin +9
We exploit data from the Pan-Andromeda Archaeological Survey (PAndAS) to study the extended structures of M31's dwarf elliptical companions, NGC147 and NGC185. Our wide-field, homo…
Spectroscopy of the three distant Andromedan satellites Cassiopeia III, Lacerta I, and Perseus I
Nicolas F. Martin, Kenneth C. Chambers, Michelle L. M. Collins +10
We present Keck II/DEIMOS spectroscopy of the three distant dwarf galaxies of M31 Lacerta I, Cassiopeia III, and Perseus I, recently discovered within the Pan-STARRS1 3πimaging sur…
Homogeneous Photometry VI: Variable Stars in the Leo I Dwarf Spheroidal Galaxy
Peter B. Stetson, Giuliana Fiorentino, Giuseppe Bono +5
We have characterized the pulsation properties of 164 candidate RR Lyrae variables (RRLs) and 55 candidate Anomalous and/or short-period Cepheids in Leo I dwarf spheroidal galaxy.…
The Complex Structure of Stars in the Outer Galactic Disk as revealed by Pan-STARRS1
Colin T. Slater, Eric F. Bell, Edward F. Schlafly +19
We present a panoptic view of the stellar structure in the Galactic disk's outer reaches commonly known as the Monoceros Ring, based on data from Pan-STARRS1. These observations cl…
Serendipitous Discovery of a Thin Stellar Stream near the Galactic Bulge in the Pan-STARRS1 3Pi Survey
Edouard J. Bernard, Annette M. N. Ferguson, Edward F. Schlafly +22
We report the discovery of a thin stellar stream found in Pan-STARRS1 photometry near the Galactic bulge in the constellation of Ophiuchus. It appears as a coherent structure in th…
The Nature and Origin of Substructure in the Outskirts of M31 -- II. Detailed Star Formation Histories
Edouard J. Bernard, Annette M. N. Ferguson, Jenny C. Richardson +9
While wide-field surveys of M31 have revealed much substructure at large radii, understanding the nature and origin of this material is not straightforward from morphology alone. U…
