Galaxy Zoo Supernovae
A. M. Smith, S. Lynn, M. Sullivan +21
This paper presents the first results from a new citizen science project: Galaxy Zoo Supernovae. This proof of concept project uses members of the public to identify supernova cand…
Hubble Space Telescope Studies of Nearby Type Ia Supernovae: The Mean Maximum Light Ultraviolet Spectrum and its Dispersion
Jeff Cooke, Richard S. Ellis, Mark Sullivan +11
We present the first results of an ongoing campaign using the STIS spectrograph on-board the Hubble Space Telescope (HST) whose primary goal is the study of near ultraviolet (UV) s…
Ultra-bright optical transients are linked with type Ic supernovae
A. Pastorello, S. J. Smartt, M. T. Botticella +41
Recent searches by unbiased, wide-field surveys have uncovered a group of extremely luminous optical transients. The initial discoveries of SN 2005ap by the Texas Supernova Search…
Rapidly Decaying Supernova 2010X: A Candidate ".Ia" Explosion
Mansi M. Kasliwal, S. R. Kulkarni, Avishay Gal-Yam +33
We present the discovery, photometric and spectroscopic follow-up observations of SN 2010X (PTF 10bhp). This supernova decays exponentially with tau_d=5 days, and rivals the curren…
Supernova Legacy Survey: Using Spectral Signatures To Improve Type Ia Supernovae As Distance Indicators
E. S. Walker, I. M. Hook, M. Sullivan +22
GMOS optical long-slit spectroscopy at the Gemini-North telescope was used to classify targets from the Supernova Legacy Survey (SNLS) from July 2005 and May 2006 - May 2008. Durin…
Real-time Analysis and Selection Biases in the Supernova Legacy Survey
K. Perrett, D. Balam, M. Sullivan +13
The Supernova Legacy Survey (SNLS) has produced a high-quality, homogeneous sample of Type Ia supernovae (SNe Ia) out to redshifts greater than z=1. In its first four years of full…
