JWST's Dusty Blue BOAT -- GRB 221009A
Nguyen M. Khang, Gavin P. Lamb, Helena-M. S. Grabham +6
GRB 221009A, the Brightest Of All Time (BOAT), presents a challenge for afterglow modelling due to its low Galactic latitude and consequent high line-of-sight extinction. This has…
A 14-year-old Mystery: The Peculiar Case of the Engine-driven SN 2012ap
Itai Sfaradi, Raffaella Margutti, Ryan Chornock +29
We present late-time ( d) optical (Keck), X-ray (Chandra and NuSTAR), and radio (VLA, ALMA, and the uGMRT) observations of the Type Ic-BL SN 2012ap. Previous studies of…
Lightcurve Modelling of 2,205 ZTF DR2 Type~Ia Supernovae: Implications for SN Ia Physics and Cosmology
Nikhil Sarin, Ellen Lindsjö, Lisa Kelsey +11
We fit the multi-band light curves of 2,205 Type Ia supernovae (SNe~Ia) from the Zwicky Transient Facility DR2 with a one-zone radioactive decay model with a phenomenological addit…
Late-Time Infrared Cooling in Magnetar-Driven Supernovae
Conor M. B. Omand
A central magnetar engine is commonly invoked to explain energetic supernovae, which should have multiple signals in multiwavelength emission. Photoionization from the pulsar wind…
Multiwavelength Modeling of the Luminous Fast Blue Optical Transient AT2024wpp
Conor M. B. Omand, Nikhil Sarin, Gavin P. Lamb +14
Luminous fast blue optical transients (LFBOTs) are a growing class of enigmatic energetic transients. They show fast rises and declines, high temperatures throughout their evolutio…
SN 2021lwz: Another Exotic Luminous and Fast Evolving Optical Stripped Envelope Supernova ?
F. Poidevin, S. L. West, C. M. B. Omand +25
Current large-scale, high-cadence surveys, such as the ZTF, provide detections of new and rare types of transients and supernovae whose physical origins are not well understood. We…
