Late-afterglow Emission from a Quasi-spherical Outflow in a stratified environment
Nissim Fraija, Boris Betancourt-Kamenetskaia, Antonio Galván +7
Gamma-ray bursts (GRBs) are cosmic events occurring at large distances beyond our galaxy. They provide a unique opportunity to study electromagnetic patterns not seen elsewhere. Wh…
A New Master Supernovae Ia sample and the investigation of the tension
M. G. Dainotti, B. De Simone, A. Garg +19
Modern cosmological research still thoroughly debates the discrepancy between local probes and the Cosmic Microwave Background observations in the Hubble constant (\texorpdfstring{…
An Optical Gamma-Ray Burst Catalogue with Measured Redshift PART I: Data Release of 535 Gamma-Ray Bursts and Colour Evolution
M. G. Dainotti, B. De Simone, R. F. Mohideen Malik +49
We present the largest optical photometry compilation of Gamma-Ray Bursts (GRBs) with redshifts (). We include 64813 observations of 535 events (including upper limits) from 28…
Polarization From A Radially Stratified Off-Axis GRB Outflow
A. C. Caligula do E. S. Pedreira, N. Fraija, A. Galvan-Gamez +5
While the dominant radiation mechanism gamma-ray bursts (GRBs) remains a question of debate, synchrotron emission is one of the foremost candidates to describe the multi-wavelength…
Afterglow Polarization from Off-Axis GRB Jets
A. C. Caligula do E. S. Pedreira, N. Fraija, A. Galvan-Gamez +5
As we further our studies on Gamma-ray bursts (GRBs), both on theoretical models and observational tools, more and more options begin to open for exploration of its physical proper…
GRB Afterglow of the Sub-relativistic Materials with Energy Injection
N. Fraija, B. Betancourt Kamenetskaia, A. Galvan-Gamez +5
Sub-relativistic materials launched during the merger of binary compact objects and the core-collapse of massive stars acquire velocity structures when expanding in a stratified en…
Modeling Gamma-ray burst Afterglow observations with an Off-axis Jet emission
Nissim Fraija, Antonio Galvan-Gamez, Boris Betancourt Kamenetskaia +5
Gamma-ray bursts (GRBs) are fascinating extragalactic objects. They represent a fantastic opportunity to investigate unique properties not exhibited in other sources. Multi-wavelen…
Afterglow light curves of the non-relativistic ejecta mass in a stratified circumstellar medium
N. Fraija, B. Betancourt Kamenetskaia, M. G. Dainotti +4
We present the afterglow light curves produced by the deceleration of the non-relativistic ejecta mass in a stratified circumstellar medium with a density profile $n(r)\propto r^{-…
Description of atypical bursts seen slightly off-axis
N. Fraija, F. De Colle, P. Veres +5
The detection of gravitational waves together with their electromagnetic counterpart, in the gamma-ray burst GRB 170817A, marked a new era of multi-messenger astronomy. Several the…
Modeling the observations of GRB 180720B: From radio to sub-TeV gamma-rays
N. Fraija, S. Dichiara, A. C. Caligula do E. S. Pedreira +6
Early and late multiwavelength observations play an important role in determining the nature of the progenitor, circumburst medium, physical processes and emitting regions associat…
Signatures from a quasi-spherical outflow and an off-axis top-hat jet launched in a merger of compact objects: An analytical approach
N. Fraija, D. Lopez-Camara, A. C. Caligula do E. S. Pedreira +3
The production of both gravitational waves and short gamma-ray bursts (sGRBs) is widely associated with the merger of compact objects. Several studies have modelled the evolution o…
Analysis and modelling of the multi-wavelength observations of the luminous GRB 190114C
N. Fraija, S. Dichiara, A. C. Caligula do E. S. Pedreira +4
Very-high-energy (VHE; GeV) photons are expected from the nearest and brightest Gamma-ray bursts (GRBs). VHE photons, at energies higher than 300 GeV, were recently repor…
Light curves of a shock-breakout material and a relativistic off-axis jet from a Binary Neutron Star system
N. Fraija, A. C. Caligula do E. S. Pedreira, P. Veres
Binary neutron star mergers are believed to eject significant masses with a diverse range of velocities. Once these ejected materials begin to be decelerated by a homogeneous mediu…
The short GRB 170817A: Modelling the off-axis emission and implications on the ejecta magnetization
N. Fraija, F. De Colle, P. Veres +4
The short GRB 170817A, detected by the Fermi Gamma-ray Burst Monitor, orbiting satellites and ground-based telescopes, was the electromagnetic counterpart of a gravitational-wave t…
