The SED Machine: A Spectrograph to Efficiently Classify Transient Events Discovered by PTF
Chow-Choong Ngeow, Nick Konidaris, Robert Quimby +4
The Palomar Transient Factory (PTF) is a project aimed to discover transients in the Universe, including Type Ia supernovae, core-collapse supernovae, and other exotic and rare tra…
Discovery and Early Multi-Wavelength Measurements of the Energetic Type Ic Supernova PTF12gzk: A Massive-Star Explosion in a Dwarf Host Galaxy
Sagi Ben-Ami, Avishay Gal-Yam, Alexei V. Filippenko +45
We present the discovery and extensive early-time observations of the Type Ic supernova (SN) PTF12gzk. Our finely sampled light curves show a rise of 0.8mag within 2.5hr. Power-law…
PTF11kx: A Type-Ia Supernova with a Symbiotic Nova Progenitor
B. Dilday, D. A. Howell, S. B. Cenko +32
There is a consensus that Type-Ia supernovae (SNe Ia) arise from the thermonuclear explosion of white dwarf stars that accrete matter from a binary companion. However, direct obser…
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…
Hubble Space Telescope studies of low-redshift Type Ia supernovae: Evolution with redshift and ultraviolet spectral trends
K. Maguire, M. Sullivan, R. S. Ellis +26
We present an analysis of the maximum light, near ultraviolet (NUV; 2900-5500 A) spectra of 32 low redshift (0.001<z<0.08) Type Ia supernovae (SNe Ia), obtained with the Hubble Spa…
Classical Novae in Andromeda: Light Curves from the Palomar Transient Factory and GALEX
Yi Cao, Mansi M. Kasliwal, James D. Neill +10
We present optical light curves of twenty-nine novae in M31 during the 2009 and 2010 observing seasons of the Palomar Transient Factory (PTF). The dynamic and rapid cadences in PTF…
