The Immediate, Exemplary, and Fleeting echelle spectroscopy of SN 2023ixf: Monitoring acceleration of slow progenitor circumstellar material, driven by shock interaction
Danielle Dickinson, Dan Milisavljevic, Braden Garretson +12
We present high resolution WIYN/NEID echelle spectroscopy (R ,000) of the supernova (SN) 2023ixf in M101, obtained 1.51 to 18.51 days after explosion over nine epochs. D…
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…
SN 2024ggi in NGC 3621: Rising Ionization in a Nearby, CSM-Interacting Type II Supernova
W. V. Jacobson-Galán, K. W. Davis, C. D. Kilpatrick +28
We present UV/optical/NIR observations and modeling of supernova (SN) 2024ggi, a type II supernova (SN II) located in NGC 3621 at 7.2 Mpc. Early-time ("flash") spectroscopy of SN 2…
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…
