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…
Physical properties of 15 quasars at
C. Mazzucchelli, E. Bañados, B. P. Venemans +21
Quasars are galaxies hosting accreting supermassive black holes; due to their brightness, they are unique probes of the early universe. To date, only few quasars have been reported…
The Pan-STARRS1 Medium-deep Survey: Star Formation Quenching in Group and Cluster Environments
Hung-Yu Jian, Lihwai Lin, Kai-Yang Lin +16
We make use of a catalog of 1600 Pan-STARRS1 groups produced by the probability friends-of-friends algorithm to explore how the galaxy properties, i.e. the specific star formation…
The Time-Domain Spectroscopic Survey: Target Selection for Repeat Spectroscopy
Chelsea L. MacLeod, Paul J. Green, Scott F. Anderson +35
As astronomers increasingly exploit the information available in the time domain, spectroscopic variability in particular opens broad new channels of investigation. Here we describ…
Astrometric evidence for a population of dislodged AGN
Valeri V. Makarov, Julien Frouard, Ciprian T. Berghea +5
We investigate a sample of 2293 ICRF2 extragalactic radio-loud sources with accurate positions determined by VLBI, mostly active galactic nuclei (AGN) and quasars, which are cross-…
