The JADES Transient Survey II: Volumetric Supernova Rates out to z~5

Christa DeCoursey, Christian Vassallo, Louis-Gregory Strolger +27

The paper uses JWST/NIRCam observations from the JADES Transient Survey to measure the first volumetric rates of core‑collapse and Type Ia supernovae at redshifts 2–5, employing ph…

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…

Feeling Blue: Constructing a Robust SALT3 UV Template and Constraining its Redshift Dependency

Qinan Wang, David O. Jones, Justin D. R. Pierel +13

Upcoming cosmological surveys will obtain numerous rest-frame ultraviolet (UV) observations of Type Ia supernovae (SNe Ia), yet there is concern about how standardizable SNe Ia are…

JWST and Keck Observations of the Off-Nuclear TDE AT 2024tvd: A Massive Nuclear Star Cluster and Minor-Merger Origin for its Black Hole

Kishore C. Patra, Ryan J. Foley, Nicholas Earl +10

We present JWST/NIRSpec and NIRCam observations of the first optically selected off-nuclear tidal disruption event (TDE), AT 2024tvd, along with Keck/KCWI integral field unit spect…

JWST Discovery of a High-Redshift Tidal Disruption Event Candidate in COSMOS-Web

Mitchell Karmen, Suvi Gezari, Erini Lambrides +26

The rates and properties of tidal disruption events (TDEs) provide valuable insights into their host galaxy central stellar densities and the demographics of their central supermas…

The First Photometric Evidence of a Transient/Variable Source at z>5 with JWST

Christa DeCoursey, Eiichi Egami, Fengwu Sun +27

The James Webb Space Telescope (JWST) discovered 79 transients out to 4.8 through the JADES Transient Survey (JTS), but the JTS did not find any 5 transients. Here,…
