The Pal 5 Star Stream Gaps
R. G. Carlberg, C. J. Grillmair, Nathan Hetherington
Pal 5 is a low mass, low velocity dispersion, globular cluster with spectacular tidal tails. We use the SDSS DR8 data to extend the density measurements of the trailing star stream…
The First Hyper-Luminous Infrared Galaxy Discovered by WISE
Peter R. M. Eisenhardt, Jingwen Wu, Chao-Wei Tsai +21
We report the discovery by the Wide-field Infrared Survey Explorer of the z = 2.452 source WISE J181417.29+341224.9, the first hyperluminous source found in the WISE survey. WISE 1…
Two Distant Halo Velocity Groups Discovered by the Palomar Transient Factory
B. Sesar, J. G. Cohen, D. Levitan +8
We report the discovery of two new halo velocity groups (Cancer groups A and B) traced by 8 distant RR Lyrae stars and observed by the Palomar Transient Factory (PTF) survey at R.A…
LAMOST Experiment for Galactic Understanding and Exploration (LEGUE) The survey science plan
Licai Deng, Heidi Jo Newberg, Chao Liu +22
We describe the current plans for a spectroscopic survey of millions of stars in the Milky Way galaxy using the Guo Shou Jing Telescope (GSJT, formerly the Large Area Multi-Object…
An Algorithm for Preferential Selection of Spectroscopic Targets in LEGUE
Jeffrey L. Carlin, Sebastien Lepine, Heidi Jo Newberg +22
We describe a general target selection algorithm that is applicable to any survey in which the number of available candidates is much larger than the number of objects to be observ…
The Palomar Transient Factory photometric catalog 1.0
E. O. Ofek, R. Laher, J. Surace +22
We construct a photometrically calibrated catalog of non-variable sources from the Palomar Transient Factory (PTF) observations. The first version of this catalog presented here, t…
