Asteroid rotation periods from the Palomar Transient Factory survey
D. Polishook, E. O. Ofek, A. Waszczak +17
The Palomar Transient Factory (PTF) is a synoptic survey designed to explore the transient and variable sky in a wide variety of cadences. We use PTF observations of fields that we…
Discovery of the Optical Transient of the Gamma Ray Burst 990308
Bradley E. Schaefer, J. A. Snyder, J. Hernandez +53
The optical transient of the faint Gamma Ray Burst 990308 was detected by the QUEST camera on the Venezuelan 1-m Schmidt telescope starting 3.28 hours after the burst. Our photomet…
The Palomar Transient Factory photometric calibration
E. O. Ofek, R. Laher, N. Law +20
The Palomar Transient Factory (PTF) provides multiple epoch imaging for a large fraction of the sky. Here we describe the photometric calibration of the PTF data products that rela…
Analysis of the Early-Time Optical Spectra of SN 2011fe in M101
J. T. Parrent, D. A. Howell, B. Friesen +35
The nearby Type Ia supernova SN 2011fe in M101 (cz=241 km s^-1) provides a unique opportunity to study the early evolution of a "normal" Type Ia supernova, its compositional struct…
Revealing the First Stellar and Supermassive Black Holes to EXIST
J. Grindlay, J. Bloom, P. Coppi +8
The epochs of origin of the first stars and galaxies, and subsequent growth of the first supermassive black holes, are among the most fundamental questions. Observations of the hig…
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…
Overview of EXIST mission science and implementation
J. Grindlay, N. Gehrels, J. Bloom +14
The Energetic X-ray Imaging Survey Telescope (EXIST) is designed to i) use the birth of stellar mass black holes, as revealed by cosmic Gamma-Ray Bursts (GRBs), as probes of the ve…
A Golden Standard Type Ia Supernova SN 2005cf: Observations from the Ultraviolet to the Near-Infrared Wavebands
Xiaofeng Wang, Weidong Li, Alexei V. Filippenko +31
We present extensive photometry at ultraviolet (UV), optical, and near-infrared (NIR) wavelengths, as well as dense sampling of optical spectra, for the normal type Ia supernova (S…
A Trio of GRB-SNe: GRB 120729A, GRB 130215A / SN 2013ez and GRB 130831A / SN 2013fu
Z. Cano, A. de Ugarte Postigo, A. Pozanenko +62
We present optical and near-infrared (NIR) photometry for three gamma-ray burst supernovae (GRB-SNe): GRB 120729A, GRB 130215A / SN 2013ez and GRB 130831A / SN 2013fu. In the case…
Multiwavelength campaign on Mrk 509. I. Variability and spectral energy distribution
J. S. Kaastra, P. -O. Petrucci, M. Cappi +23
(Abridged) Active galactic nuclei show a wealth of interesting physical processes, some of which are poorly understood. We want to address a number of open questions, including the…
The SAMI Galaxy Survey: the link between angular momentum and optical morphology
L. Cortese, L. M. R. Fogarty, K. Bekki +34
We investigate the relationship between stellar and gas specific angular momentum , stellar mass and optical morphology for a sample of 488 galaxies extracted from the S…
Optical follow-up of GRB 970508
T. J. Galama, P. J. Groot, J. van Paradijs +14
We report on the results of optical follow-up observations of the counterpart of GRB 970508, starting 7 hours after the event. Multi-color U, B, V, R and I band observa…
The SAMI Galaxy Survey: Towards a unified dynamical scaling relation for galaxies of all types
L. Cortese, L. M. R. Fogarty, I. -T. Ho +27
We take advantage of the first data from the Sydney-AAO Multi-object Integral field (SAMI) Galaxy Survey to investigate the relation between the kinematics of gas and stars, and st…
High-redshift GRB 140304A at z = 5.282 with flaring activity: A multi-wavelength study
