Comparing the size evolution of GRB 221009A with afterglow models

S. Giarratana, O. S. Salafia, B. Marcote +10

We present very long baseline interferometry (VLBI) observations of GRB221009A obtained with the global-VLBI network at 5 GHz between 231 and 750 days after the burst. The quality…

Constraining inhomogeneities and asymmetries in SNe, FBOTs, and other high-energy transients from unresolved radio observations

Fabio De Colle, Rosa L. Becerra, Lizeth A. Meza +7

Synchrotron emission in high-energy transients is produced by relativistic electrons accelerated by shocks. As high-energy transients are often unresolved even on angular scales pr…

Failed jet breakout in the metal-poor broad-lined type Ic supernova 2026gzf

Antonio Martin-Carrillo, Christina C. Thöne, James K. Leung +103

A long-standing question in the death of massive stars is the role of relativistic jets. While many gamma-ray bursts and some fast X-ray transients seem to be associated with broad…

GRB 240205B: A Reverse Shock Detected in Rapid Response Radio Observations

S. I. Chastain, G. E. Anderson, A. J. van der Horst +6

Here we present broadband radio modeling of GRB 240205B, using observations with the Australia Telescope Compact Array (ATCA) and the South African MeerKAT radio telescope. Our obs…

VLBI Observations of SN 2012au Reveal a Compact Radio Source a Decade Post Explosion

Mattias Lazda, Kenzie Nimmo, Maria R. Drout +13

Three leading models have been put forth to justify the observed radio re-brightening associated with stripped-envelope supernovae (SESNe) years post-explosion: radiation from an e…
