TITAN DR1: An Improved, Validated, and Systematically-Controlled Recalibration of ATLAS Photometry toward Type Ia Supernova Cosmology

Elijah G. Marlin, Yukei S. Murakami, Dillon Brout +14

ATLAS (Asteroid Terrestrial Last Alert System) is a time-domain survey using four telescopes, covering the entire sky. It has observed over 10,000 spectroscopically confirmed Type…

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…

Type Ia supernova growth-rate measurement with LSST simulations: intrinsic scatter systematics

Bastien Carreres, Rebecca C. Chen, Erik R. Peterson +9

Measurement of the growth rate of structures ($\fsig$) with Type Ia supernovae (\sns) will improve our understanding of the nature of dark energy and enable tests of general relati…
