The Bright Supernova 1996cr in the Circinus Galaxy Imaged with VLBI: Shell Structure with Complex Evolution

Michael F. Bietenholz, Norbert Bartel, Vikram V. Dwarkadas +5

We present broadband radio flux-density measurements supernova (SN) 1996cr, made with MeerKAT, ATCA and ALMA, and images made from very long baseline interferometry (VLBI) observat…

SN 2014C: VLBI image shows a shell structure and decelerated expansion

Michael F. Bietenholz, Norbert Bartel, Atish Kamble +3

We report on new Very Long Baseline Interferometry radio measurements of supernova 2014C in the spiral galaxy NGC 7331, made with the European VLBI Network ~5 yr after the explosio…

The Radio Luminosity-Risetime Function of Core-Collapse Supernovae

Michael F. Bietenholz, N. Bartel, M. Argo +3

We assemble a large set of 2-10 GHz radio flux density measurements and upper limits of 294 different supernovae (SNe), from the literature and our own and archival data. Only 31%…

AT 2018cow VLBI: No Long-Lived Relativistic Outflow

Michael F. Bietenholz, Raffaella Margutti, Deanne Coppejans +7

We report on VLBI observations of the fast and blue optical transient (FBOT), AT 2018cow. At ~62 Mpc, AT 2018cow is the first relatively nearby FBOT. The nature of AT 2018cow is no…

Recent VLBI Results on SN 1986J and the Possibility of FRBs Originating from Inside the Expanding Ejecta of Supernovae

Michael F. Bietenholz, Norbert Bartel

We discuss our VLA and VLBI observations of supernova 1986J, which is characterized by a compact radio-bright component within the expanding shell of ejecta. No other supernova (SN…

On the Possibility of Fast Radio Bursts from Inside Supernovae: The Case of SN 1986J

Michael F. Bietenholz, Norbert Bartel

We discuss the possibility of obtaining Fast Radio Bursts (FRBs) from the interior of supernovae, in particular SN 1986J. Young neutron stars are involved in many of the possible s…
