The Pantheon+ Analysis: Cosmological Constraints
Dillon Brout, Dan Scolnic, Brodie Popovic +43
We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from t…
Towards the Future of Supernova Cosmology
Michelle Lochner, Bruce A. Bassett, Melvin Varughese +4
For future surveys, spectroscopic follow-up for all supernovae will be extremely difficult. However, one can use light curve fitters, to obtain the probability that an object is a…
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…
Photometric Supernova Cosmology with BEAMS and SDSS-II
Renée Hlozek, Martin Kunz, Bruce Bassett +16
Supernova cosmology without spectroscopic confirmation is an exciting new frontier which we address here with the Bayesian Estimation Applied to Multiple Species (BEAMS) algorithm…
