Testing for Intrinsic Type Ia Supernova Luminosity Evolution at z>2 with JWST

J. D. R. Pierel, D. A. Coulter, M. R. Siebert +38

The James Webb Space Telescope} (JWST) is opening new frontiers of transient discovery and follow-up at high-redshift. Here we present the discovery of a spectroscopically confirme…

Shockingly Bright Warm Carbon Monoxide Molecular Features in the Supernova Remnant Cassiopeia A Revealed by JWST

J. Rho, S. -H. Park, R. Arendt +36

We present JWST NIRCam (F356W and F444W filters) and MIRI (F770W) images and NIRSpec- IFU spectroscopy of the young supernova remnant Cassiopeia A (Cas A). We obtained the data as…

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…

Deep JWST/NIRCam imaging of Supernova 1987A

Mikako Matsuura, M. Boyer, Richard G. Arendt +46

JWST/NIRCam obtained high angular-resolution (0.05-0.1''), deep near-infrared 1--5 micron imaging of Supernova (SN) 1987A taken 35 years after the explosion. In the NIRCam images,…

Emission lines due to ionizing radiation from a compact object in the remnant of Supernova 1987A

C. Fransson, M. J. Barlow, P. J. Kavanagh +31

The nearby Supernova 1987A was accompanied by a burst of neutrino emission, which indicates that a compact object (a neutron star or black hole) was formed in the explosion. There…

JWST MIRI Imager Observations of Supernova SN 1987A

P. Bouchet, R. Gastaud, A. Coulais +31

There exist very few mid-infrared (IR) observations of supernovae (SNe) in general. Therefore, SN 1987A, the closest visible SN in 400 years, gives us the opportunity to explore th…
