The evolution of the mid-infrared spectrum of SN 1987A observed with the JWST/MIRI-MRS

P. J. Kavanagh, M. J. Barlow, C. Fransson +19

Supernova (SN) 1987A provides a unique laboratory for investigating many aspects of SN physics and evolution. An observation at Day 12927 (35.4 yr) since the explosion with the Mid…

The compact object and innermost ejecta of SN 1987A

J. Larsson, C. Fransson, P. J. Kavanagh +12

The first JWST observations of SN 1987A provided clear evidence that a compact object is ionizing the innermost ejecta. Here we analyze a second epoch of JWST NIRSpec and MIRI/MRS…

The Green Monster hiding in front of Cas A: JWST reveals a dense and dusty circumstellar structure pockmarked by ejecta interactions

Ilse De Looze, Dan Milisavljevic, Tea Temim +27

JWST observations of the young Galactic supernova remnant Cassiopeia A revealed an unexpected structure seen as a green emission feature in colored composite MIRI F1130W and F1280W…

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…

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…
