A new approach for obtaining cosmological constraints from Type Ia Supernovae using Approximate Bayesian Computation
Elise Jennings, Rachel Wolf, Masao Sako
Cosmological parameter estimation techniques that robustly account for systematic measurement uncertainties will be crucial for the next generation of cosmological surveys. We pres…
Host Galaxy Identification for Supernova Surveys
Ravi R. Gupta, Steve Kuhlmann, Eve Kovacs +57
Host galaxy identification is a crucial step for modern supernova (SN) surveys such as the Dark Energy Survey (DES) and the Large Synoptic Survey Telescope (LSST), which will disco…
SDSS-II Supernova Survey: An Analysis of the Largest Sample of Type Ia Supernovae and Correlations with Host-Galaxy Spectral Properties
Rachel C. Wolf, Chris B. D'Andrea, Ravi R. Gupta +13
Using the largest single-survey sample of Type Ia supernovae (SNe Ia) to date, we study the relationship between properties of SNe Ia and those of their host galaxies, focusing pri…
DES14X3taz: A Type I Superluminous Supernova Showing a Luminous, Rapidly Cooling Initial Pre-Peak Bump
M. Smith, M. Sullivan, C. B. D'Andrea +81
We present DES14X3taz, a new hydrogen-poor super luminous supernova (SLSN-I) discovered by the Dark Energy Survey (DES) supernova program, with additional photometric data provided…
