The very high energy view of gamma-ray bursts with the MAGIC telescopes
Alessio Berti, Željka Bošnjak, Alberto Castro-Tirado +22
Gamma-ray bursts (GRBs) are one of the main targets for the observations of the MAGIC telescopes. As a result of the effort in improving the sensitivity of the instrument and the a…
Optical polarization of stellar-fed active and quiescent supermassive black holes
N. Jordana-Mitjans, A. Franckowiak, E. Ramírez-Ruiz +4
Using the MOPTOP polarimeter on the 2-meter Liverpool Telescope, we conducted a monitoring campaign targeting three optically-discovered TDEs (AT2024bgz, AT2024pvu, and AT2024wsd)…
Back from the dead: AT2019aalc as a candidate repeating TDE in an AGN
Patrik Milán Veres, Anna Franckowiak, Sjoert van Velzen +15
Context. To date, three nuclear transients have been associated with high-energy neutrino events. These transients are generally thought to be powered by tidal disruptions of stars…
MAGIC detection of GRB 201216C at
H. Abe, S. Abe, V. A. Acciari +217
Gamma-ray bursts (GRBs) are explosive transient events occurring at cosmological distances, releasing a large amount of energy as electromagnetic radiation over several energy band…
GRB minimum variability timescale with Insight-HXMT and Swift: implications for progenitor models, dissipation physics and GRB classifications
A. E. Camisasca, C. Guidorzi, L. Amati +18
The dissipation process of GRB prompt emission is still unknown. Study of temporal variability may provide a unique way to discriminate the imprint of the inner engine activity fro…
The role of the magnetic fields in GRB outflows
N. Jordana-Mitjans, C. G. Mundell, S. Kobayashi +12
Gamma-ray bursts (GRBs) are bright extragalactic flashes of gamma-ray radiation and briefly the most energetic explosions in the Universe. Their catastrophic origin (the merger of…
A short gamma-ray burst from a proto-magnetar remnant
N. Jordana-Mitjans, C. G. Mundell, C. Guidorzi +10
The contemporaneous detection of gravitational waves and gamma rays from the GW170817/GRB 170817A, followed by kilonova emission a day after, confirmed compact binary neutron-star…
Polarimetry and Photometry of Gamma-Ray Bursts Afterglows with RINGO3
M. Shrestha, I. A. Steele, S. Kobayashi +7
We present photometric and polarimetric measurements of gamma-ray burst (GRB) optical afterglows observed by the RINGO3 imaging polarimeter over its 7 year lifetime mounted o…
GRB 191016A: A highly collimated gamma-ray burst jet with magnetised energy injection
M. Shrestha, I. A. Steele, S. Kobayashi +7
Long gamma-ray burst GRB 191016A was a bright and slow rising burst that was detected by the \textit{Swift} satellite and followed up by ground based Liverpool Telescope (LT). LT f…
Radio data challenge the broadband modelling of GRB160131A afterglow
M. Marongiu, C. Guidorzi, G. Stratta +6
Context. Gamma-ray burst (GRB) afterglows originate from the interaction between the relativistic ejecta and the surrounding medium. Consequently, their properties depend on severa…
Coherence scale of magnetic fields generated in early-time forward shocks of GRBs
N. Jordana-Mitjans, C. G. Mundell, R. J. Smith +6
We report the earliest-ever detection of optical polarization from a GRB forward shock (GRB 141220A), measured s after the burst using the multi-colour RINGO3 optica…
Lowly polarized light from a highly magnetized jet of GRB 190114C
N. Jordana-Mitjans, C. G. Mundell, S. Kobayashi +12
We report multi-color optical imaging and polarimetry observations of the afterglow of the first TeV- detected gamma-ray burst, GRB 190114C, using RINGO3 and MASTER II polarimeters…
