SMHASH: Anatomy of the Orphan Stream using RR Lyrae stars
David Hendel, Victoria Scowcroft, Kathryn V. Johnston +30
Stellar tidal streams provide an opportunity to study the motion and structure of the disrupting galaxy as well as the gravitational potential of its host. Streams around the Milky…
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 Outer Halo of the Milky Way as Probed by RR Lyr Variables from the Palomar Transient Facility
Judith Cohen, Branimir Sesar, Sophianna Bahnolzer +5
RR Lyr stars are ideal massless tracers that can be used to study the total mass and dark matter content of the outer halo of the Milky Way. This is because they are easy to find i…
Census of the Local Universe (CLU) Narrow-Band Survey I: Galaxy Catalogs from Preliminary Fields
David O. Cook, Mansi M. Kasliwal, Angela Van Sistine +13
We present the Census of the Local Universe (CLU) narrow-band survey to search for emission-line (\ha) galaxies. CLU-\ha~has imaged 3 of the sky (26,470~deg) with 4…
Disk Heating, Galactoseismology, and the Formation of Stellar Halos
Kathryn V. Johnston, Adrian M. Price-Whelan, Maria Bergemann +7
Deep photometric surveys of the Milky Way have revealed diffuse structures encircling our Galaxy far beyond the "classical" limits of the stellar disk. This paper reviews results f…
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…
