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…

Lensed Type Ia Supernova "Encore" at z=2: The First Instance of Two Multiply-Imaged Supernovae in the Same Host Galaxy

J. D. R. Pierel, A. B. Newman, S. Dhawan +60

A bright (=24 mag), supernova (SN) candidate was discovered in JWST/NIRCam imaging acquired on 2023 November 17. The SN is quintuply-imaged as a result o…

LensWatch: I. Resolved HST Observations and Constraints on the Strongly-Lensed Type Ia Supernova 2022qmx ("SN Zwicky")

J. D. R. Pierel, N. Arendse, S. Ertl +39

Supernovae (SNe) that have been multiply-imaged by gravitational lensing are rare and powerful probes for cosmology. Each detection is an opportunity to develop the critical tools…

SALT3-NIR: Taking the Open-Source Type Ia Supernova Model to Longer Wavelengths for Next-Generation Cosmological Measurements

J. D. R. Pierel, D. O. Jones, W. D. Kenworthy +32

A large fraction of Type Ia supernova (SN Ia) observations over the next decade will be in the near-infrared (NIR), at wavelengths beyond the reach of the current standard light-cu…

Relative intrinsic scatter in hierarchical Type Ia supernova siblings analyses: Application to SNe 2021hpr, 1997bq & 2008fv in NGC 3147

Sam M. Ward, Stephen Thorp, Kaisey S. Mandel +22

We present Young Supernova Experiment photometry of SN 2021hpr, the third Type Ia supernova sibling to explode in the Cepheid calibrator galaxy, NGC 3147. Siblings are usef…
