The Roman eXtreme Deep Field (RXDF)
Haojing Yan, Anton M. Koekemoer, Yue Shen +127
The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in…
A spectroscopically confirmed, strongly lensed, metal-poor Type II supernova at z = 5.13
David A. Coulter, Conor Larison, Justin D. R. Pierel +88
Observing supernovae (SNe) in the early Universe (z > 3) provides a window into how both galaxies and individual stars have evolved over cosmic time, yet a detailed study of high-r…
Expanding the High-z Supernova Frontier: "Wide-Area" JWST Discoveries from the First Two Years of COSMOS-Web
Ori D. Fox, Armin Rest, Justin D. R. Pierel +48
Transient astronomy in the early Universe (z > 2) remains largely unexplored, lying beyond the rest-frame optical spectroscopic reach of most current observatories. Yet this regime…
Optimizing Convolution Direction and Template Selection for Difference Image Analysis
Rodrigo Angulo, Armin Rest, William P. Blair +8
Difference image analysis (DIA) is a powerful tool for studying time-variable phenomena, and has been used by many time-domain surveys. Most DIA algorithms involve matching the spa…
SpectAcLE: An Improved Method for Modeling Light Echo Spectra
Roee Partoush, Armin Rest, Jacob E. Jencson +17
Light echoes give us a unique perspective on the nature of supernovae and non-terminal stellar explosions. Spectroscopy of light echoes can reveal details on the kinematics of the…
Supernova 2020wnt: An Atypical Superluminous Supernova with a Hidden Central Engine
Samaporn Tinyanont, Stan E. Woosley, Kirsty Taggart +34
We present observations of a peculiar hydrogen- and helium-poor stripped-envelope (SE) supernova (SN) 2020wnt, primarily in the optical and near-infrared (near-IR). Its peak absolu…
Revealing the progenitor of SN 2021zby through analysis of the shock-cooling light curve
Qinan Wang, Patrick Armstrong, Yossef Zenati +34
We present early observations and analysis of the double-peaked Type IIb supernova (SN IIb) 2021zby. captured the prominent early shock cooling peak of SN 2021zby within the…
The Circumstellar Environments of Double-Peaked, Calcium-strong Supernovae 2021gno and 2021inl
Wynn Jacobson-Galán, Padma Venkatraman, Raffaella Margutti +42
We present panchromatic observations and modeling of calcium-strong supernovae (SNe) 2021gno in the star-forming host galaxy NGC 4165 (D = 30.5 Mpc) and 2021inl in the outskirts of…
