The effect of peculiar velocities on supernova cosmology
Tamara M Davis, Lam Hui, Joshua A Frieman +11
We present an analysis of peculiar velocities and their effect on supernova cosmology. In particular, we study (a) the corrections due to our own motion, (b) the effects of correla…
Spectral properties of Type Ia supernovae up to z~0.3
J. Nordin, L. Ostman, A. Goobar +10
Aims: Spectroscopic observations of Type Ia supernovae obtained at the New Technology Telescope (NTT) and the Nordic Optical Telescope (NOT), in conjunction with the SDSS-II Supern…
Statistical Classification Techniques for Photometric Supernova Typing
James Newling, Melvin Varughese, Bruce A. Bassett +8
Future photometric supernova surveys will produce vastly more candidates than can be followed up spectroscopically, highlighting the need for effective classification methods based…
A Mismatch in the Ultraviolet Spectra between Low-Redshift and Intermediate-Redshift Type Ia Supernovae as a Possible Systematic Uncertainty for Supernova Cosmology
Ryan J. Foley, Alexei V. Filippenko, Richard Kessler +11
We present Keck high-quality rest-frame ultraviolet (UV) through optical spectra of 21 Type Ia supernovae (SNe Ia) in the redshift range 0.11 < z < 0.37 and a mean redshift of 0.22…
Optical discovery of probable stellar tidal disruption flares
Sjoert van Velzen, Glennys R. Farrar, Suvi Gezari +6
Using archival SDSS multi-epoch imaging data (Stripe 82), we have searched for the tidal disruption of stars by super-massive black holes in non-active galaxies. Two candidate tida…
Single or Double Degenerate Progenitors? Searching for Shock Emission in the SDSS-II Type Ia Supernovae
Brian T. Hayden, Peter M. Garnavich, Daniel Kasen +10
From the set of nearly 500 spectroscopically confirmed type~Ia supernovae and around 10,000 unconfirmed candidates from SDSS-II, we select a subset of 108 confirmed SNe Ia with wel…
