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…
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…
The Deepest Radio Observations of Nearby Type IA Supernovae: Constraining Progenitor Types and Optimizing Future Surveys
Peter Lundqvist, Esha Kundu, Miguel A. Perez-Torres +7
We report deep radio observations of nearby Type Ia Supernovae (SNe Ia) with the electronic Multi-Element Radio Linked Interferometer Net-work (e-MERLIN), and the Australia Telesco…
The Impact of the Environment of White Dwarf Mergers on Fast Radio Bursts
Esha Kundu, Lilia Ferrario
Fast radio bursts (FRBs) are transient intense radio pulses with duration of milliseconds. Although the first FRB was detected more than a decade ago, the progenitors of these ener…
