GRB minimum variability timescales with Fermi/GBM
R. Maccary, C. Guidorzi, A. E. Camisasca +8
Context. Gamma-ray bursts (GRBs) have traditionally been classified by duration into long (LGRBs) and short (SGRBs), with the former believed to originate from massive star collaps…
The puzzling long GRB 191019A: Evidence for Kilonova Light
G. Stratta, A. M. Nicuesa Guelbenzu, S. Klose +11
GRB 191019A was a long Gamma-ray burst (GRB) lasting about 65 s and, as such, originally thought to be linked to a core-collapse supernova. However, even though follow-up observati…
New results on the gamma-ray burst variability-luminosity relation
C. Guidorzi, R. Maccary, A. Tsvetkova +13
At the dawn of the gamma-ray burst (GRB) afterglow era, a Cepheid-like correlation was discovered between time variability V and isotropic-equivalent peak luminosity Liso of the pr…
Distribution of the number of peaks within a long gamma-ray burst: The full Fermi/GBM catalogue
R. Maccary, M. Maistrello, C. Guidorzi +8
Context. The dissipation process responsible for the long gamma-ray burst (GRB) prompt emission and the kind of dynamics that drives the release of energy as a function of time are…
Distribution of number of peaks within a long gamma-ray burst
C. Guidorzi, M. Sartori, R. Maccary +10
The variety of long duration gamma-ray burst (LGRB) light curves (LCs) encode a wealth of information on how LGRB engines release energy following the collapse of the progenitor st…
Distributions of energy, luminosity, duration, and waiting times of gamma-ray burst pulses with known redshift detected by Fermi/GBM
R. Maccary, C. Guidorzi, L. Amati +6
Discovered more than 50 years ago, gamma-ray burst (GRB) prompt emission remains the most puzzling aspect of GRB physics. Its complex and irregular nature should reveal how newborn…
Optimising the observation of optical kilonovae with medium size telescopes
A. E. Camisasca, I. A. Steele, M. Bulla +2
We consider the optimisation of the observing strategy (cadence, exposure time and filter choice) using medium size (2-m class) optical telescopes in the follow-up of kilonovae loc…
Insight-HXMT and GECAM-C observations of the brightest-of-all-time GRB 221009A
Zheng-Hua An, S. Antier, Xing-Zi Bi +174
GRB 221009A is the brightest gamma-ray burst ever detected since the discovery of this kind of energetic explosions. However, an accurate measurement of the prompt emission propert…
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…
