JWST/MIRI Observations of Newly Formed Dust in the Cold, Dense Shell of the Type IIn SN 2005ip
Melissa Shahbandeh, Ori D. Fox, Tea Temim +42
Dust from core-collapse supernovae (CCSNe), specifically Type IIP SNe, has been suggested to be a significant source of the dust observed in high-redshift galaxies. CCSNe eject lar…
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…
Strong rest-UV emission lines in a "little red dot" AGN at : Early SMBH growth alongside compact massive star formation?
Hollis B. Akins, Caitlin M. Casey, Danielle A. Berg +11
JWST has now revealed a population of broad-line AGN at characterized by a distinctive SED shape, with very red rest-frame optical and very blue rest-frame UV continuum. Whil…
Constraining Dust Formation in the Superluminous Supernova 2017gci with JWST Observations
Sebastian Gomez, Tea Temim, Ori Fox +11
We present JWST/MIRI observations of the Type I superluminous supernova (SLSN) 2017gci taken over 2000 rest-frame days after the supernova (SN) exploded, which represent the latest…
Investigating the Electron Capture Supernova Candidate AT 2019abn with JWST Spectroscopy
Sam Rose, Ryan M. Lau, Jacob E. Jencson +5
The James Webb Space Telescope (JWST) has opened up a new window to study highly reddened explosive transients. We present results from late-time (1421 days post-explosion) JWST fo…
The Type I Superluminous Supernova Catalog I: Light Curve Properties, Models, and Catalog Description
Sebastian Gomez, Matt Nicholl, Edo Berger +25
We present the most comprehensive catalog to date of Type I Superluminous Supernovae (SLSNe), a class of stripped envelope supernovae (SNe) characterized by exceptionally high lumi…
