JWST Nebular Spectroscopy of SN 2023qov: Circumstellar Dust Emission in a Normal Type Ia Supernova
Colin W. Macrie, Conor Larison, Huei Sears +42
We present panchromatic observations of the Type Ia supernova (SN Ia) 2023qov, ranging from 2 weeks before to 1 year after maximum light. \textit{JWST} near- and mid-in…
The Weighing Halos Accurately, Locally, and Efficiently with Supernovae (WHALES) Survey Overview and Initial Data Release
Maria Acevedo, Daniel Scolnic, Bastien Carreres +6
We present an overview of the Weighing Halos Accurately, Locally, and Efficiently with Supernovae (WHALES) survey, the first to discover and measure Type Ia supernovae (SNe Ia) in…
The Dark Energy Bedrock All-Sky Supernova Program: Cross Calibration, Simulations, and Cosmology Forecasts
Maria Acevedo, Nora F. Sherman, Dillon Brout +12
Type Ia supernovae (SNe Ia) have been essential for probing the nature of dark energy; however, most SN analyses rely on the same low-redshift sample, which may lead to shared syst…
The Dark Energy Bedrock All-Sky Supernova Program: Motivation, Design, Implementation, and Preliminary Data Release
Nora F. Sherman, Maria Acevedo, Dillon Brout +20
Precise measurements of Type Ia supernovae (SNe Ia) at low redshifts () serve as one of the most viable keys to unlocking our understanding of cosmic expansion, isotropy, and gr…
