Studying the Diversity of Type Ia Supernovae in the Ultraviolet: Comparing Models with Observations
E. S. Walker, S. Hachinger, P. A. Mazzali +4
In the ultraviolet (UV), Type Ia supernovae (SNe Ia) show a much larger diversity in their properties than in the optical. Using a stationary Monte-Carlo radiative transfer code, a…
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…
Evolution in the Volumetric Type Ia Supernova Rate from the Supernova Legacy Survey
K. Perrett, M. Sullivan, A. Conley +23
We present a measurement of the volumetric Type Ia supernova (SN Ia) rate (SNR_Ia) as a function of redshift for the first four years of data from the Canada-France-Hawaii Telescop…
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…
