Revealing the Nature of Extreme Coronal-line Emitter SDSS J095209.56+214313.3
Lovro Palaversa, Suvi Gezari, Branimir Sesar +4
Extreme coronal-line emitter (ECLE) SDSSJ095209.56+214313.3, known by its strong, fading, high ionization lines, has been a long standing candidate for a tidal disruption event, ho…
Evidence of Fanning in the Ophiuchus Stream
B. Sesar, A. M. Price-Whelan, J. G. Cohen +11
The Ophiuchus stellar stream presents a dynamical puzzle: its old stellar populations ( Gyr) cannot be reconciled with (1) its orbit in a simple model for the Milky Way po…
Finding, characterizing and classifying variable sources in multi-epoch sky surveys: QSOs and RR Lyrae in PS1 3 data
Nina Hernitschek, Edward F. Schlafly, Branimir Sesar +14
In area and depth, the Pan-STARRS1 (PS1) 3 survey is unique among many-epoch, multi-band surveys and has enormous potential for all-sky identification of variable sources. PS1 h…
The Outer Galactic Halo As Probed By RR Lyr Stars From the Palomar Transient Facility + Keck
Judith G. Cohen, Branimir Sesar, Sophianna Banholzer +1
We present initial results from our study of the outer halo of the Milky Way using a large sample of RR Lyr(ab) variables datamined from the archives of the Palomar Transient Facil…
Sagittarius II, Draco II and Laevens 3: three new Milky Way satellites discovered in the Pan-STARRS 1 3pi Survey
Benjamin P. M. Laevens, Nicolas F. Martin, Edouard J. Bernard +17
We present the discovery of three new Milky Way satellites from our search for compact stellar overdensities in the photometric catalog of the Panoramic Survey Telescope and Rapid…
The radial profile and flattening of the Milky Way's stellar halo to kpc from the SEGUE K-giant Survey
Xiang-Xiang Xue, Hans-Walter Rix, Zhibo Ma +4
We characterise the radial density, metallicity and flattening profile of the Milky Way's stellar halo, based on the large sample of 1757 spectroscopically confirmed giant stars fr…
A New Faint Milky Way Satellite Discovered in the Pan-STARRS1 3 pi Survey
Benjamin P. M. Laevens, Nicolas F. Martin, Rodrigo A. Ibata +21
We present the discovery of a faint Milky Way satellite, Laevens 2/Triangulum II, found in the Panoramic Survey Telescope And Rapid Response System (Pan-STARRS 1) 3 pi imaging data…
A re-interpretation of the Triangulum-Andromeda stellar clouds: a population of halo stars kicked out of the Galactic disk
Adrian M. Price-Whelan, Kathryn V. Johnston, Allyson A. Sheffield +2
The Triangulum-Andromeda stellar clouds (TriAnd1 and TriAnd2) are a pair of concentric ring- or shell-like over-densities at large ( 30 kpc) and ( -10 kpc…
The Nature and Orbit of the Ophiuchus Stream
B. Sesar, J. Bovy, E. J. Bernard +20
The Ophiuchus stream is a recently discovered stellar tidal stream in the Milky Way. We present high-quality spectroscopic data for 14 stream member stars obtained using the Keck a…
