A census of AM CVn stars: three new candidates and one confirmed 48.3-minute binary (2009)
Rau, Arne, Roelofs, Gijs H. A., Groot, Paul J., Marsh, Tom R., Nelemans, Gijs, Steeghs, Danny, ...
We present three new candidate AM CVn binaries, plus one confirmed new system, from a spectroscopic survey of color-selected objects from the Sloan Digital Sky Survey. All four systems were found...
Exploring the Optical Transient Sky with the Palomar Transient Factory (2009)
Rau, Arne, Kulkarni, Shrinivas R., Law, Nicholas M., Bloom, Joshua S., Ciardi, David, Djorgovski, George S., ...
The Palomar Transient Factory (PTF) is a wide-field experiment designed to investigate the optical transient and variable sky on time scales from minutes to years. PTF uses the CFH12k mosaic camera,...
The Impact of the Astro2010 Recommendations on Variable Star Science (2009)
Walkowicz, Lucianne M., Becker, Andrew C., Anderson, Scott F., Bloom, Joshua S., Georgiev, Leonid, Grindlay, Josh, ...
The next decade of survey astronomy has the potential to transform our knowledge of variable stars. Stellar variability underpins our knowledge of the cosmological distance ladder, and provides...

GRB 070125: The first long-duration gamma-ray burst in a halo environment (2008)
Cenko, S. Bradley, Fox, Derek B., Penprase, Brian E., Cucchiara, Antonio, Price, Paul A., Berger, Edo, ...
We present the discovery and high signal-to-noise ratio spectroscopic observations of the optical afterglow of the long-duration gamma-ray burst GRB 070125. Unlike all previously observed...
A comprehensive study of GRB 070125, a most energetic gamma ray burst (2008)
Chandra, Poonam, Cenko, S. Bradley, Frail, Dale, Chevalier, Roger, Macquart, Jean-Pierre, Kulkarni, Shri, ...
We present a comprehensive multiwavelength analysis of the bright, long duration gamma-ray burst GRB 070125, comprised of observations in $\gamma$-ray, X-ray, optical, millimeter and centimeter...
Cenko, S. Bradley, Berger, Edo, Nakar, Ehud, Kasliwal, Mansi M., Cucchiara, Antonio, Kulkarni, Shri R., ...
We present optical spectra of the host galaxies of the short-duration gamma-ray burst GRB 070429B and the likely short-duration with extended emission GRB 070714B. In both cases, we find a single...
Gamma-ray bursts are the witnesses of stellar explosions at cosmological distances and among the most energetic phenomena in the Universe. Here I present a study of the population of Gamma-ray bursts...

The host galaxy of GRB 011121: Morphology and Spectral Energy Distribution (2006)
Yoldas, Aybuke Kupcu, Salvato, Mara, Greiner, Jochen, Pierini, Daniele, Pian, Elena, Rau, Arne
(Abridged) We present a detailed study of the host galaxy of GRB 011121 (at z = 0.36) based on high-resolution imaging in 5 broad-band, optical and near-infrared filters with HST and VLT/ISAAC. The...
Constraining the GRB Collimation with a Survey for Orphan Afterglows (2006)
Rau, Arne, Greiner, Jochen, Schwarz, Robert
Gamma-ray bursts are believed to be produced in highly-relativistic collimated outflows. Support for this comes among others from the association of the times of detected breaks in the decay of...
Evolution of the polarization of the optical afterglow of the y-ray burst GRB030329 (2003)
Greiner, Jochen, Klose, Sylvio, Reinsch, Klaus, Schmid, Hans Martin, Sari, Re'em, Hartmann, Dieter H., ...
We analyzed 139 chi-state observations of GRS 1915+105 with RXTE from 1997 to 2000 and found i) that the observations fall into two groups with different Comptonization behavior, ii) that the slope...
We present a comprehensive X-ray study of four years of pointed RXTE observations of GRS 1915+105 in the chi-state. We interpret the behavior of the hard power law tail spectrum as coming from...
