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…

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…

Properties of high-redshift Type II supernovae discovered by the JADES transient survey

Takashi J. Moriya, David A. Coulter, Christa DeCoursey +23

In this work we estimate the explosion and progenitor properties of six Type II supernovae (SNe) at 0.675 <= z <= 3.61 discovered by the James Webb Space Telescope (JWST) Advanced…

TESS photometry of the nova eruption in V606 Vul: asymmetric photosphere and multiple ejections?

Kirill V. Sokolovsky, Elias Aydi, Konstantin Malanchev +70

Lightcurves of many classical novae deviate from the canonical "fast rise - smooth decline" pattern and display complex variability behavior. We present the first TESS-space-photom…

The JADES Transient Survey: Discovery and Classification of Supernovae in the JADES Deep Field

Christa DeCoursey, Eiichi Egami, Justin D. R. Pierel +35

The JWST Advanced Deep Extragalactic Survey (JADES) is a multi-cycle JWST program that has taken among the deepest near-/mid-infrared images to date (down to 30 ABmag) over $…
