The Fermi GBM GRBs' multivariate statistics
Istvan I. Racz, Lajos G. Balázs, Zsolt Bagoly +2
Studying the GRBs' gamma-ray spectra may reveal some physical information of Gamma-ray Bursts. The Fermi satellite observed more than two thousand GRBs. The FERMIGBRST catalog cont…
Studying the variability of the X-ray spectral parameters of high-redshift GRBs' afterglows
Istvan I. Racz, Agnes J. Hortobagyi
The Swift satellite has observed more than a thousand GRBs with X-ray data. Almost a third of them have redshift measurement, too. Here we start to investigate the X-ray spectral f…
Exploring the pattern of the Galactic HI foreground of GRBs with the ATCA
H. Denes, P. A. Jones, L. V. Toth +12
The afterglow of a gamma ray burst (GRB) can give us valuable insight into the properties of its host galaxy. To correctly interpret the spectra of the afterglow we need to have a…
Gaussian-mixture-model-based cluster analysis of gamma-ray bursts in the BATSE catalog
B. G. Tóth, I. I. Rácz, I. Horváth
Clustering is an important tool to describe gamma-ray bursts (GRBs). We analyzed the Final BATSE Catalog using Gaussian-mixture-models-based clustering methods for six variables (d…
Multidimensional analysis of Fermi GBM gamma-ray bursts
I. Horvath, J. Hakkila, Z. Bagoly +4
The Fermi GBM catalog provides a large database with many measured variables that can be used to explore and verify gamma-ray burst classification results. We have used Principal C…
