AT2025ulz and S250818k: zooming in with the Hubble Space Telescope

Yu-Han Yang, Eleonora Troja, Marko Ristić +19

AT2025ulz is an optical/near-infrared transient discovered during follow-up of the candidate gravitational wave (GW) event S250818k. Its young age (1 d), rapid decline an…

A JWST Survey of the Supernova Remnant Cassiopeia A

Dan Milisavljevic, Tea Temim, Ilse De Looze +43

We present initial results from a JWST survey of the youngest Galactic core-collapse supernova remnant Cassiopeia A (Cas A), made up of NIRCam and MIRI imaging mosaics that map emi…

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…

JWST MIRI flight performance: Detector Effects and Data Reduction Algorithms

Jane Morrison, Daniel Dicken, Ioannis Argyriou +21

The detectors in the Mid-Infrared Instrument (MIRI) of the James Webb Space Telescope (JWST) are arsenic-21 doped silicon impurity band conduction (Si:As IBC) devices and are direc…

Ground-based and JWST Observations of SN 2022pul: I. Unusual Signatures of Carbon, Oxygen, and Circumstellar Interaction in a Peculiar Type Ia Supernova

Matthew R. Siebert, Lindsey A. Kwok, Joel Johansson +79

Nebular-phase observations of peculiar Type Ia supernovae (SNe Ia) provide important constraints on progenitor scenarios and explosion dynamics for both these rare SNe and the more…

Ground-based and JWST Observations of SN 2022pul: II. Evidence from Nebular Spectroscopy for a Violent Merger in a Peculiar Type-Ia Supernova

Lindsey A. Kwok, Matthew R. Siebert, Joel Johansson +78

We present an analysis of ground-based and JWST observations of SN~2022pul, a peculiar "03fg-like" (or "super-Chandrasekhar") Type Ia supernova (SN Ia), in the nebular phase at 338…
