The width of gamma-ray burst spectra
Magnus Axelsson, Luis Borgonovo
The emission processes active in the highly relativistic jets of gamma-ray bursts (GRBs) remain unknown. In this paper we propose a new measure to describe spectra: the width of th…
Factor analysis of the spectral and time behavior of long GRBs
Z. Bagoly, L. Borgonovo, I. Horvath +2
A sample of 197 long BATSE GRBs is studied statistically. In the sample 11 variables, describing for any burst the time behavior of the spectra and other quantities, are collected.…
Factor analysis of the long gamma-ray bursts
Z. Bagoly, L. Borgonovo, A. Meszaros +2
We study statistically 197 long gamma-ray bursts, detected and measured in detail by the BATSE instrument of the Compton Gamma-Ray Observatory. In the sample 10 variables, describi…
Vanishing hardness-flux correlation in Cygnus X-1: signs of the disc moving out
M. Axelsson, L. Hjalmarsdotter, L. Borgonovo +1
Aims. We investigate observations of the X-ray binary Cygnus X-1 with unusually high hardness and low flux. In particular, we study the characteristic frequencies seen in the PDS a…
Principal Component Analysis of Gamma-Ray Bursts' Spectra
Z. Bagoly, I. Horvath, L. G. Balazs +4
Principal component analysis is a statistical method, which lowers the number of important variables in a data set. The use of this method for the bursts' spectra and afterglows is…
On the temporal variability classes found in long gamma-ray bursts with known redshift
L. Borgonovo, F. Frontera, C. Guidorzi +3
Based on the analysis of a small sample of BATSE and Konus gamma-ray bursts (GRBs) with know redshift it has been reported that the width of the autocorrelation function (ACF) show…
