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…
Colour evolution in the radio afterglow of GRB 241025A
S. Giarratana, O. S. Salafia, L. Nava +10
We present the observing campaign of the afterglow of GRB241025A, a gamma-ray burst (GRB) whose prompt emission has been simultaneously detected by Swift, Einstein Probe, Fermi/GBM…
Gamma-ray Bursts in the Radio Sky: the Role of the SKA-VLBI
Stefano Giarratana, Om Sharan Salafia, Xue-Feng Wu +6
Radio observations of -ray bursts (GRBs) employing the very long baseline interferometry (VLBI) technique provide us with fundamental information on the dynamics and the geometr…
Discovery and Analysis of Afterglows from Poorly Localised GRBs with the Gravitational-wave Optical Transient Observer (GOTO) All-sky Survey
Amit Kumar, B. P. Gompertz, B. Schneider +86
Gamma-ray bursts (GRBs), particularly those detected by wide-field instruments such as the Fermi/GBM, pose a challenge for optical follow-up due to their large initial localisation…
Probing multi-band variability and mode switching in the candidate transitional millisecond pulsar 3FGL J1544.6-1125
Giulia Illiano, Francesco Coti Zelati, Arianna Miraval Zanon +20
We present the most extensive high-time resolution multi-band campaign to date on the candidate transitional millisecond pulsar (tMSP) 3FGL J1544.6-1125 in the sub-luminous disk st…
Multi-band study of the flaring mode emission in the transitional millisecond pulsar PSR J1023+0038
M. C. Baglio, F. Coti Zelati, A. K. Hughes +17
We present a comprehensive study of the flaring mode of the transitional millisecond pulsar (tMSP) PSR J1023+0038 during its X-ray sub-luminous state, using strictly simultaneous X…
The radio afterglow of the ultra-long GRB 220627A
James K. Leung, Om Sharan Salafia, Cristiana Spingola +13
We present the discovery of the radio afterglow of the most distant ultra-long gamma-ray burst (GRB) detected to date, GRB~220627A at redshift . Its prompt gamma-ray light…
Polarized multiwavelength emission from pulsar wind - accretion disk interaction in a transitional millisecond pulsar
M. C. Baglio, F. Coti Zelati, A. Di Marco +17
Transitional millisecond pulsars (tMSPs) bridge the evolutionary gap between accreting neutron stars in low-mass X-ray binaries and millisecond radio pulsars. These systems exhibit…
Rocking the BOAT: the ups and downs of the long-term radio light curve for GRB 221009A
L. Rhodes, A. J. van der Horst, J. S. Bright +24
We present radio observations of the long-duration gamma-ray burst (GRB) 221009A which has become known to the community as the Brightest Of All Time or the BOAT. Our observations…
The Northern Cross Fast Radio Burst project IV. Multi-wavelength study of the actively repeating FRB 20220912A
D. Pelliciari, G. Bernardi, M. Pilia +26
Fast radio bursts (FRBs) are energetic, millisecond-duration radio pulses observed at extragalactic distances and whose origins are still a subject of heated debate. A fraction of…
The expansion of the GRB 221009A afterglow
S. Giarratana, O. S. Salafia, M. Giroletti +14
We observed -ray burst (GRB) 221009A using very long baseline interferomety (VLBI) with the European VLBI Network (EVN) and the Very Long Baseline Array (VLBA), over a period sp…
Matter ejections behind the highs and lows of the transitional millisecond pulsar PSR J1023+0038
M. C. Baglio, F. Coti Zelati, S. Campana +23
Transitional millisecond pulsars are an emerging class of sources that link low-mass X-ray binaries to millisecond radio pulsars in binary systems. These pulsars alternate between…
Bursts from Space: MeerKAT - The first citizen science project dedicated to commensal radio transients
Alex Andersson, Chris Lintott, Rob Fender +40
The newest generation of radio telescopes are able to survey large areas with high sensitivity and cadence, producing data volumes that require new methods to better understand the…
Precise Measurements of Self-absorbed Rising Reverse Shock Emission from Gamma-ray Burst 221009A
Joe S. Bright, Lauren Rhodes, Wael Farah +18
The deaths of massive stars are sometimes accompanied by the launch of highly relativistic and collimated jets. If the jet is pointed towards Earth, we observe a "prompt" gamma-ray…
