Extending the SKA Across Africa: The Case for a Continental African VLBI Network
Emmanuel K. Bempong-Manful, Jompoj Wongphechauxsorn, Jack Radcliffe +31
The African continent holds the key to unlocking the full potential of global Very Long Baseline Interferometry (VLBI). Strategic placement of radio telescopes across Africa provid…
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…
Revisiting FRB 20121102A: milliarcsecond localisation and a decreasing dispersion measure
M. P. Snelders, J. W. T. Hessels, J. Huang +27
FRB 20121102A is the original repeating fast radio burst (FRB) source and also the first to be localised to milliarcsecond precision using very-long-baseline interferometry (VLBI).…
High-resolution imaging of the evolving bipolar outflows in symbiotic novae: The case of the RSOphiuchi 2021 nova outburst
R. Lico, M. Giroletti, U. Munari +6
The recurrent and symbiotic nova RS Ophiuchi (RSOph) underwent a new outburst phase during August 2021, about 15 years after the last event that occurred in 2006. This outburst rep…
