Tracing dark energy history with gamma ray bursts
M. Muccino, L. Izzo, O. Luongo +5
Observations of gamma-ray bursts up to are best suited to study the possible evolution of the Universe equation of state at intermediate redshifts. We apply the Combo-rel…
Colour variations in the GRB 120327A afterglow
A. Melandri, S. Covino, E. Zaninoni +42
We present a comprehensive temporal and spectral analysis of the long Swift GRB 120327A afterglow data to investigate the possible causes of the observed early time colour variatio…
Update on the GRB universal scaling E-E-E with ten years of data
Elena Zaninoni, Maria Grazia Bernardini, Raffaella Margutti +1
From a comprehensive statistical analysis of X-ray light-curves of gamma-ray bursts (GRBs) collected from December 2004 to the end of 2010, we found a three-parameter corre…
New measurements of from gamma-ray bursts
Luca Izzo, Marco Muccino, Elena Zaninoni +2
Context: Data from cosmic microwave background radiation (CMB), baryon acoustic oscillations (BAO), and supernovae Ia (SNe-Ia) support a constant dark energy equation of state with…
GRB 140619B: a short GRB from a binary neutron star merger leading to black hole formation
R. Ruffini, M. Muccino, M. Kovacevic +8
We show the existence of two families of short GRBs, both originating from the merger of binary neutron stars (NSs): family-1 with erg, leading to a massive NS as…
Gamma-ray burst optical light-curve zoo: comparison with X-ray observations
Elena Zaninoni, Maria Grazia Bernardini, Raffaella Margutti +2
We present a comprehensive analysis of the optical and X-ray light curves (LCs) and spectral energy distributions (SEDs) of a large sample of gamma-ray burst (GRB) afterglows to in…
A comprehensive statistical analysis of Swift X-ray light-curves: the prompt-afterglow connection in Gamma-Ray Bursts
Raffaella Margutti, E. Zaninoni, M. G. Bernardini +1
We present a comprehensive statistical analysis of Swift X-ray light-curves of Gamma-Ray Bursts (GRBs), with more than 650 GRBs. Two questions drive this effort: (1) Does the X-ray…
A universal scaling for short and long gamma-ray bursts: E_{X,iso}-E_{gamma,iso}-E_{pk}
M. G. Bernardini, R. Margutti, E. Zaninoni +1
The comprehensive statistical analysis of Swift X-ray light-curves, collecting data from six years of operation, revealed the existence of a universal scaling among the isotropic e…
The prompt-afterglow connection in Gamma-Ray Bursts: a comprehensive statistical analysis of Swift X-ray light-curves
R. Margutti, E. Zaninoni, M. G. Bernardini +20
We present a comprehensive statistical analysis of Swift X-ray light-curves of Gamma-Ray Bursts (GRBs) collecting data from more than 650 GRBs discovered by Swift and other facilit…
The X-ray light curve of Gamma-ray bursts: clues to the central engine
M. G. Bernardini, R. Margutti, J. Mao +2
We present the analysis of a large sample of gamma-ray burst (GRB) X-ray light curves in the rest frame to characterise their intrinsic properties in the context of different theor…
The Swift/XRT Catalogue of GRBs
Elena Zaninoni, Raffaella Margutti, Maria Grazia Bernardini +1
We present the preliminary analysis of the GRB light curves obtained by Swift/XRT between November 2004 and December 2010.
X-ray flare candidates in short gamma-ray bursts
R. Margutti, G. Chincarini, J. Granot +7
We present the first systematic study of X-ray flare candidates in short gamma-ray bursts (SGRBs) exploiting the large 6-year Swift database with the aim to constrain the physical…
