Radio Supernovae
Esha Kundu
Supernovae (SNe), the catastrophic end of stars' lives, are among the most energetic phenomena in the universe. Mapping the aftermath of the explosions to the properties of pre-SN…
A Multi-Wavelength View on the Rapidly-Evolving Supernova 2018ivc: An Analog of SN IIb 1993J but Powered Primarily by Circumstellar Interaction
Keiichi Maeda, Poonam Chandra, Takashi J. Moriya +15
SN 2018ivc is an unusual type II supernova (SN II). It is a variant of SNe IIL, which might represent a transitional case between SNe IIP with a massive H-rich envelope, and IIb wi…
Constraining the Progenitor System of the Type Ia Supernova 2021aefx
Griffin Hosseinzadeh, David J. Sand, Peter Lundqvist +25
We present high-cadence optical and ultraviolet light curves of the normal Type Ia supernova (SN) 2021aefx, which shows an early bump during the first two days of observation. This…
Is FRB 191001 embedded in a supernova remnant?
Esha Kundu
Fast radio burst (FRB) 191001 is localised at the spiral arm of a highly star-forming galaxy with an observed dispersion measure (DM) of 507 pc cm. Subtracting the contribut…
Free-free absorption in hot relativistic flows: application to fast radio bursts
Esha Kundu, Bing Zhang
Magnetic flares create hot relativistic shocks outside the light cylinder radius of a magnetised star. Radio emission produced in such a shock or at a radius smaller than the shock…
The final months of massive star evolution from the circumstellar environment around SN Ic 2020oi
Keiichi Maeda, Poonam Chandra, Tomoki Matsuoka +8
We present the results of ALMA band 3 observations of a nearby type Ic supernova (SN) 2020oi. Under the standard assumptions on the SN-circumstellar medium (CSM) interaction and th…
