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…
A flash of polarized optical light points to an aspherical "cow"
J. R. Maund, P. A. Hoeflich, I. A. Steele +8
The astronomical transient AT2018cow is the closest example of the new class of luminous, fast blue optical transients (FBOTs). Liverpool Telescope RINGO3 observations of AT2018cow…
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…
Methods for detection and analysis of weak radio sources with single-dish radio telescopes
M. Marongiu, A. Pellizzoni, E. Egron +13
The detection of mJy/sub-mJy point sources is a significant challenge for single-dish radio telescopes. Detection or upper limits on the faint afterglow from GRBs or other sources…
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…
