Discovery of a likely Type II SN at =3.6 with JWST
D. A. Coulter, J. D. R. Pierel, C. DeCoursey +30
Transient astronomy in the early, high-redshift (z > 3) Universe is an unexplored regime that offers the possibility of probing the first stars and the Epoch of Reionization. Durin…
Discovery of a Relativistic Stripped Envelope Type Ic-BL Supernova at z = 2.83 with JWST
M. R. Siebert, C. Decoursey, D. A. Coulter +26
We present JWST NIRCam and NIRSpec observations of a Type Ic supernova (SN Ic) and its host galaxy (JADES-GS+53.13533-27.81457) at . This SN (named SN 2023adta) was ident…
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 $…
Dissecting the Crab Nebula with JWST: Pulsar wind, dusty filaments, and Ni/Fe abundance constraints on the explosion mechanism
Tea Temim, J. Martin Laming, P. J. Kavanagh +19
We present JWST observations of the Crab Nebula, the iconic remnant of the historical SN 1054. The observations include NIRCam and MIRI imaging mosaics, plus MIRI/MRS IFU spectra t…
ATClean: A Novel Method for Detecting Low-Luminosity Transients and Application to Pre-explosion Counterparts from SN 2023ixf
S. Rest, A. Rest, C. D. Kilpatrick +16
In an effort to search for faint sources of emission over arbitrary timescales, we present a novel method for analyzing forced photometry light curves in difference imaging from op…
Serendipitous detection of the dusty Type IIL SN 1980K with JWST/MIRI
Szanna Zsíros, Tamás Szalai, Ilse De Looze +39
We present mid-infrared (mid-IR) imaging of the Type IIL supernova (SN) 1980K with the James Webb Space Telescope (JWST) more than 40 yr post-explosion. SN 1980K, located in the ne…
