Infrahumps detected in Kepler light curve of V1504 Cygni
Robert Coyne, Ashwin Shenoy, Glen MacLachlan +6
We present a power spectral density analysis of the short cadence Kepler data for the cataclysmic variable V1504 Cygni. We identify three distinct periods: the orbital period (1.66…
Berkeley Supernova Ia Program I: Observations, Data Reduction, and Spectroscopic Sample of 582 Low-Redshift Type Ia Supernovae
Jeffrey M. Silverman, Ryan J. Foley, Alexei V. Filippenko +37
In this first paper in a series we present 1298 low-redshift (z\leq0.2) optical spectra of 582 Type Ia supernovae (SNe Ia) observed from 1989 through 2008 as part of the Berkeley S…
The origin of the early time optical emission of Swift GRB 080310
O. M. Littlejohns, R. Willingale, P. T. O'Brien +28
We present broadband multi-wavelength observations of GRB 080310 at redshift z = 2.43. This burst was bright and long-lived, and unusual in having extensive optical and near IR fol…
Minimum Variability Time Scales of Long and Short GRBs
G. A. MacLachlan, A. Shenoy, E. Sonbas +7
We have investigated the time variations in the light curves from a sample of long and short Fermi/GBM Gamma ray bursts (GRBs) using an impartial wavelet analysis. The results indi…
