The Structure and Stellar Content of the Outer Disks of Galaxies: A New View from the Pan-STARRS1 Medium Deep Survey
Z. Zheng, D. Thilker, T. Heckman +11
We present the results of an analysis of Pan-STARRS1 Medium Deep Survey multi-band (g,r,i,z,y) images of a sample of 698 low-redshift disk galaxies that span broad ranges in stella…
3D Dust Mapping Reveals that Orion Forms Part of a Large Ring of Dust
E. F. Schlafly, G. Green, D. P. Finkbeiner +12
The Orion Molecular Complex is the nearest site of ongoing high-mass star formation, making it one of the most extensively studied molecular complexes in the Galaxy. We have develo…
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…
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…
