Detection of an Orphan X-ray Flare from a Blazar Candidate EP240709a with Einstein Probe

Mingjun Liu, Yijia Zhang, Yun Wang +49

Blazars are often observed to flare across multiple wavelengths. Orphan flares from blazars have been only detected a few times, providing an opportunity to understand the structur…

SN 2021foa: The "Flip-Flop" Type IIn / Ibn supernova

D. Farias, C. Gall, G. Narayan +29

We present a comprehensive analysis of the photometric and spectroscopic evolution of SN~2021foa, unique among the class of transitional supernovae for repeatedly changing its spec…

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…

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…

WTP19aalnxx: Discovery of a bright mid-infrared transient in the emerging class of low luminosity supernovae revealed by delayed circumstellar interaction

Charlotte Myers, Kishalay De, Lin Yan +11

While core-collapse supernovae (SNe) often show early and consistent signs of circumstellar (CSM) interaction, some exhibit delayed signatures due to interaction with distant mater…

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…
