Superluminous Supernovae from the Dark Energy Survey
C. R. Angus, M. Smith, M. Sullivan +72
We present a sample of 21 hydrogen-free superluminous supernovae (SLSNe-I), and one hydrogen-rich SLSN (SLSN-II) detected during the five-year Dark Energy Survey (DES). These SNe,…
A Search for Optical Emission from Binary-Black-Hole Merger GW170814 with the Dark Energy Camera
Z. Doctor, R. Kessler, K. Herner +96
Binary black hole (BBH) mergers found by the LIGO and Virgo detectors are of immense scientific interest to the astrophysics community, but are considered unlikely to be sources of…
First Cosmology Results Using Type Ia Supernovae from the Dark Energy Survey: Effects of Chromatic Corrections to Supernova Photometry on Measurements of Cosmological Parameters
J. Lasker, R. Kessler, D. Scolnic +78
Calibration uncertainties have been the leading systematic uncertainty in recent analyses using type Ia Supernovae (SNe Ia) to measure cosmological parameters. To improve the calib…
The Foundation Supernova Survey: Measuring Cosmological Parameters with Supernovae from a Single Telescope
D. O. Jones, D. M. Scolnic, R. J. Foley +27
Measurements of the dark energy equation-of-state parameter, , have been limited by uncertainty in the selection effects and photometric calibration of Type Ia supernova…
First Cosmology Results using Type Ia Supernova from the Dark Energy Survey: Simulations to Correct Supernova Distance Biases
R. Kessler, D. Brout, C. B. D'Andrea +103
We describe catalog-level simulations of Type Ia supernova (SN~Ia) light curves in the Dark Energy Survey Supernova Program (DES-SN), and in low-redshift samples from the Center fo…
First Cosmology Results Using Type Ia Supernovae From the Dark Energy Survey: Analysis, Systematic Uncertainties, and Validation
D. Brout, D. Scolnic, R. Kessler +122
We present the analysis underpinning the measurement of cosmological parameters from 207 spectroscopically classified type Ia supernovae (SNe Ia) from the first three years of the…
