Cosmology with Photometrically-Classified Type Ia Supernovae from the SDSS-II Supernova Survey
Heather Campbell, Chris B. D'Andrea, Robert C. Nichol +25
We present the cosmological analysis of 752 photometrically-classified Type Ia Supernovae (SNe Ia) obtained from the full Sloan Digital Sky Survey II (SDSS-II) Supernova (SN) Surve…
BEAMS: separating the wheat from the chaff in supernova analysis
Martin Kunz, Renée Hlozek, Bruce A. Bassett +3
We introduce Bayesian Estimation Applied to Multiple Species (BEAMS), an algorithm designed to deal with parameter estimation when using contaminated data. We present the algorithm…
How Flat is Our Universe Really?
P. M. Okouma, Y. Fantaye, B. A. Bassett
Distance measurement provide no constraints on curvature independent of assumptions about the dark energy, raising the question, how flat is our Universe if we make no such assumpt…
Extending BEAMS to incorporate correlated systematic uncertainties
Michelle Lochner, Bruce A. Bassett, Melvin Varughese +4
New supernova surveys such as the Dark Energy Survey, Pan-STARRS and the LSST will produce an unprecedented number of photometric supernova candidates, most with no spectroscopic d…
