Constraints on the Galactic Inner Halo Assembly History from the Age Gradient of Blue Horizontal-branch Stars
Devin D. Whitten, Timothy C. Beers, Vinicius M. Placco +6
We present an analysis of the relative age distribution of the Milky Way halo, based on samples of blue horizontal-branch (BHB) stars obtained from the Panoramic Survey Telescope a…
The Complete Calibration of the Color-Redshift Relation (C3R2) Survey: Analysis and Data Release 2
Daniel C. Masters, Daniel K. Stern, Judith G. Cohen +11
The Complete Calibration of the Color-Redshift Relation (C3R2) survey is a multi-institution, multi-instrument survey that aims to map the empirical relation of galaxy color to red…
Precision distances to dwarf galaxies and globular clusters from Pan-STARRS1 3 RR Lyrae
Nina Hernitschek, Judith G. Cohen, Hans-Walter Rix +6
We present new spatial models and distance estimates for globular clusters (GC) and dwarf spheroidals (dSphs) orbiting our Galaxy based on RR Lyrae (RRab) stars in the Pan-STARRS1…
Connecting the Milky Way potential profile to the orbital timescales and spatial structure of the Sagittarius Stream
Mark A. Fardal, Roeland P. van der Marel, David R. Law +4
Recent maps of the halo using RR Lyrae from Pan-STARRS1 have clearly depicted the spatial structure of the Sagittarius stream. These maps show the leading and trailing stream apoce…
The Geometry of Sagittarius Stream from Pan-STARRS1 3 RR Lyrae
Nina Hernitschek, Branimir Sesar, Hans-Walter Rix +11
We present a comprehensive and precise description of the Sagittarius (Sgr) stellar stream's 3D geometry as traced by its old stellar population. This analysis draws on the sample…
The kpc Distant Spur of the Sagittarius Stream and the Outer Virgo Overdensity, as Seen in PS1 RR Lyrae Stars
Branimir Sesar, Nina Hernitschek, Marion I. P. Dierickx +2
We report the detection of spatially distinct stellar density features near the apocenters of the Sagittarius (Sgr) stream's main leading and trailing arm. These features are clear…
