A set of distinctive properties ruling the prompt emission of GRB 230307A and other long γ-ray bursts from compact object mergers
R. Maccary, C. Guidorzi, M. Maistrello +9
Short gamma-ray bursts (SGRBs), occasionally followed by a long and spectrally soft extended emission, are associated with compact object mergers (COMs). Yet, a few recent long GRB…
SVOM GRB 250314A at z 7.3: an exploding star in the era of reionization
B. Cordier, J. Y. Wei, N. R. Tanvir +103
Most long Gamma-ray bursts originate from a rare type of massive stellar explosion. Their afterglows, while rapidly fading, can be initially extremely luminous at optical/near-infr…
HERMES Pathfinder & SpIRIT: a progress report
F. Fiore, M. Trenti, Y. Evangelista +87
HERMES Pathfinder is an in-orbit demonstration consisting of a constellation of six 3U cubesats hosting simple but innovative X-ray/gamma-ray detectors for the monitoring of cosmic…
Long Pulse by Short Central Engine: Prompt emission from expanding dissipation rings in the jet front of gamma-ray bursts
Shu-Xu Yi, Emre Seyit Yorgancioglu, S. -L. Xiong +1
Recent observations have challenged the long-held opinion that the duration of gamma-ray burst (GRB) prompt emission is determined by the activity epochs of the central engine. Spe…
Evidence of mini-jet emission in a large emission zone from a magnetically-dominated gamma-ray burst jet
S. -X. Yi, C. -W. Wang, X. -Y. Shao +42
The second brightest GRB in history, GRB230307A, provides an ideal laboratory to study the mechanism of GRB prompt emission thanks to its extraordinarily high photon statistics and…
Magnetar emergence in a peculiar gamma-ray burst from a compact star merger
H. Sun, C. -W. Wang, J. Yang +42
The central engine that powers gamma-ray bursts (GRBs), the most powerful explosions in the universe, is still not identified. Besides hyper-accreting black holes, rapidly spinning…
The First GECAM Observation Results on Terrestrial Gamma-ray Flashes and Terrestrial Electron Beams
Y. Zhao, J. C. Liu, S. L. Xiong +59
Gravitational-wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) is a space-borne instrument dedicated to monitoring high-energy transients, including Terrestrial…
Simultaneous and panchromatic observations of the Fast Radio Burst FRB 20180916B
M. Trudu, M. Pilia, L. Nicastro +47
Aims. Fast Radio Bursts are bright radio transients whose origin has not yet explained. The search for a multi-wavelength counterpart of those events can put a tight constrain on t…
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…
Peculiar disk behaviors of the black hole candidate MAXI J1348-630 in the hard state observed by Insight-HXMT and Swift
W. Zhang, L. Tao, R. Soria +93
We present a spectral study of the black hole candidate MAXI J1348-630 during its 2019 outburst, based on monitoring observations with Insight-HXMT and Swift. Throughout the outbur…
