Optical transients from non-explosive double white-dwarf mergers: the case of a central neutron star remnant
M. M. Ridha Fathima, Alexandre M. R. Almeida, Mattia Bulla +3
Discoveries of ultra-massive magnetic white dwarfs (WDs) and peculiar pulsars have been proposed to originate in double white dwarf (DWD) mergers. There are three possible post-mer…
GRB X-ray plateaus as evidence that the afterglow begins before the prompt gamma-ray emission
C. Guidorzi, R. Maccary, M. Maistrello +3
Most GRB X-ray afterglow light curves are characterised by a plateau, followed by a normal power-law decay interpreted as afterglow emission. Despite the numerous alternative inter…
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…
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…
Gamma-ray burst taxonomy: looking for the third class on the spectral peak energy-duration plane in the rest frame
Anastasia Tsvetkova, Lorenzo Amati, Mattia Bulla +8
Two classes of Gamma-ray bursts (GRBs), corresponding to the short/hard and the long/soft events, with a putative intermediate class, are typically considered in the observer frame…
A search for periodic activity in multi-peaked long gamma-ray bursts
C. Guidorzi, M. Orlandini, R. Maccary +10
A sizeable fraction of gamma-ray burst (GRB) light curves (LCs) features a sequence of peaks, which holds information on the unknown way energy is dissipated into gamma-rays over t…
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…
Long gamma-ray burst light curves as the result of a common stochastic pulse-avalanche process
Lorenzo Bazzanini, Lisa Ferro, Cristiano Guidorzi +9
Context. The complexity and variety exhibited by the light curves of long gamma-ray bursts (GRBs) enclose a wealth of information that still awaits being fully deciphered. Despite…
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…
POSSIS: predicting spectra, light curves and polarization for multi-dimensional models of supernovae and kilonovae
Mattia Bulla
We present POSSIS, a time-dependent three-dimensional Monte Carlo code for modelling radiation transport in supernovae and kilonovae. The code incorporates wavelength- and time-dep…
