Detection of disk-jet co-precession in a tidal disruption event
Yanan Wang, Zikun Lin, Linhui Wu +46
Theories and simulations predict that intense spacetime curvature near black holes bends the trajectories of light and matter, driving disk and jet precession under relativistic to…
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).…
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…
The radio flare and multi-wavelength afterglow of the short GRB 231117A: energy injection from a violent shell collision
G. E. Anderson, G. P. Lamb, B. P. Gompertz +64
We present the early radio detection and multi-wavelength modeling of the short gamma-ray burst (GRB) 231117A at redshift . The Australia Telescope Compact Array automatic…
Radio Emission from a Nearby M dwarf Binary
Kelvin Wandia, Michael A. Garrett, Robert J. Beswick +7
We present the detection of the binary system 2MASS J02132062+3648506 AB using the Karl G. Jansky Very Large Array (VLA) archive data observed at 4-8 GHz. The system is a triple co…
Comprehensive Radio Monitoring of the Black Hole X-ray Binary Swift J1727.81613 during its 20232024 Outburst
Andrew K. Hughes, Francesco Carotenuto, Thomas D. Russell +39
This work presents comprehensive multi-frequency radio monitoring of the black hole low-mass X-ray binary Swift J1727.81613, which underwent its first recorded outburst after it…
Thermal electrons in the radio afterglow of relativistic tidal disruption event ZTF22aaajecp/AT2022cmc
Lauren Rhodes, Ben Margalit, Joe S. Bright +11
A tidal disruption event (TDE) occurs when a star travels too close to a supermassive black hole. In some cases, accretion of the disrupted material onto the black hole launches a…
The peculiar hard state behaviour of the black hole X-ray binary Swift J1727.81613
A. K. Hughes, F. Carotenuto, T. D. Russell +37
Tracking the correlation between radio and X-ray luminosities during black hole X-ray binary outbursts is a key diagnostic of the coupling between accretion inflows (traced by X-ra…
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…
An e-MERLIN & EVN radio counterpart to the ultraluminous X-ray source M82 X-1
D. Williams-Baldwin, T. W. B. Muxlow, G. Lucatelli +1
Ultra-luminous X-ray sources (ULXs) are X-ray bright (L310erg s) extra-galactic objects that are powered by either neutron stars, or stellar o…
Quantifying jet-interstellar medium interactions in Cyg X-1: Insights from dual-frequency bow shock detection with MeerKAT
P. Atri, S. E. Motta, Jakob van den Eijnden +6
Accretion and outflows are astrophysical phenomena observed across a wide range of objects, from white dwarfs to supermassive black holes. Developing a complete picture of these pr…
New insights on supernova remnants and HII regions in M82
D. Williams-Baldwin, G. Lucatelli, T. W. B. Muxlow +7
The nearby (d=3.6 Mpc) starburst galaxy M82 has been studied for several decades by very long baseline interferometry (VLBI) networks such as e-MERLIN and the European VLBI Network…
A consistent radio to sub-mm pc-scale study of the nucleus of NGC 1068
Isaac M. Mutie, Santiago del Palacio, Robert J. Beswick +5
The origin of radio emission in radio-quiet (RQ) AGN remains a long-standing mystery. We present a detailed study of the cm to sub-mm emission from the nucleus of the nearby protot…

Xiaopeng Cheng, Tao An, Willem Baan +5
We report the results of high-resolution 5 GHz Very Long Baseline Array and European VLBI Network observations of 36 nearby galaxies, an extension of the Legacy e-MERLIN Multi-band…
The observed phase space of mass-loss history from massive stars based on radio observations of a large supernova sample
Itai Sfaradi, Assaf Horesh, Rob Fender +4
In this work we study the circumstellar material (CSM) around massive stars, and the mass-loss rates depositing this CSM, using a large sample of radio observations of 325 core-col…
