The Mass Dependence of Dwarf Satellite Galaxy Quenching
Colin T. Slater, Eric F. Bell
We combine observations of the Local Group with data from the NASA-Sloan Atlas to show the variation in the quenched fraction of satellite galaxies from low mass dwarf spheroidals…
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…
Galactic Globular and Open Cluster Fiducial Sequences in the Pan-STARRS1 Photometric System
Edouard J. Bernard, Annette M. N. Ferguson, Edward F. Schlafly +16
We present the fiducial sequences of a sample of Galactic star clusters in the five bands of the Pan-STARRS1 (PS1) photometric system (g_P1, r_P1, i_P1, z_P1, y_P1). These empirica…
A new distant Milky Way globular cluster in the Pan-STARRS1 3π survey
Benjamin P. M. Laevens, Nicolas F. Martin, Branimir Sesar +20
We present a new satellite in the outer halo of the Galaxy, the first Milky Way satellite found in the stacked photometric catalog of the Panoramic Survey Telescope and Rapid Respo…
