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…

Probing Physical Conditions in Classical and Symbiotic Novae with the Square Kilometre Array Observatory

Rocco Lico, Marcello Giroletti, Arnau Aguasca-Cabot +9

Cataclysmic variables and symbiotic stars are interacting binary systems in which a hot white dwarf (WD) orbits a companion main-sequence or red giant star, respectively. Accumulat…

A milliarcsecond localization associates FRB 20190417A with a compact persistent radio source and an extreme magneto-ionic environment

Alexandra M. Moroianu, Shivani Bhandari, Maria R. Drout +38

We report the milliarcsecond localization of a high (1379 pc/cc) dispersion measure (DM) repeating fast radio burst, FRB 20190417A. Combining European VLBI Network detections of fi…

A Hyperactive FRB Pinpointed in an SMC-Like Satellite Host Galaxy

M. Bhardwaj, M. P. Snelders, J. W. T. Hessels +24

Precise localizations of fast radio bursts (FRBs) are essential for uncovering their host galaxies and immediate environments. We present the milliarcsecond-precision European VLBI…

High-resolution radio observations of TeV candidate sources

J. Kőmíves, K. É. Gabányi, S. Frey +3

Radio-loud active galactic nuclei (AGN) with their jets pointed close to our line of sight constitute the majority of extragalactic -ray sources and significantly contribute to…

A Repeating Fast Radio Burst Source in a Low-Luminosity Dwarf Galaxy

Danté M. Hewitt, Mohit Bhardwaj, Alexa C. Gordon +48

We present the localization and host galaxy of FRB 20190208A, a repeating source of fast radio bursts (FRBs) discovered using CHIME/FRB. As part of the PRECISE repeater localizatio…
