Does the GRB Duration Depend on Redshift?
I. Horvath, I. I. Racz, Z. Bagoly +2
Several hundred gamma-ray burst (GRB) redshifts have been determined to date. One of the other important properties-besides the distance-of the GRBs is the duration of the burst. I…
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…
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…
Statistical properties of Fermi GBM GRBs' spectra
Istvan I. Racz, Lajos G. Balázs, Istvan Horvath +2
Statistical studies of gamma-ray burst (GRB) spectra may result in important information on the physics of GRBs. The Fermi GBM catalog contains GRB parameters (peak energy, spectra…
Properties of Short Gamma-Ray Burst Pulses from A BATSE TTE GRB Pulse Catalog
Jon Hakkila, Istvan Horvath, Eric Hofesmann +1
We analyze pulse properties of Short gamma-ray bursts (GRBs) from a new catalog containing 434 pulses from 387 BATSE Time-Tagged Event (TTE) GRBs. Short GRB pulses exhibit correlat…
The duration distribution of Swift Gamma-Ray Bursts
I. Horvath, B. G. Toth
Decades ago two classes of gamma-ray bursts were identified and delineated as having durations shorter and longer than about 2 s. Subsequently indications also supported the existe…
Searching for electromagnetic counterpart of LIGO gravitational waves in the Fermi GBM data with ADWO
Z. Bagoly, D. Szécsi, L. G. Balázs +5
The Fermi collaboration identified a possible electromagnetic counterpart of the gravitational wave event of September 14, 2015. Our goal is to provide an unsupervised data analysi…
New data support the existence of the Hercules-Corona Borealis Great Wall
Istvan Horvath, Zsolt Bagoly, Jon Hakkila +1
Several large structures, including the Sloan Great Wall, the Huge Large Quasar Group, and a large gamma-ray burst cluster referred to as the Hercules-Corona Borealis Great Wall, a…
Are gamma-ray bursts cosmological?
I. Horvath
Gamma-ray burst sources are distributed with a high level of isotropy, which is compatible with either a cosmological origin or an extended Galactic halo origin. The brightness dis…
Redshift and spatial distribution of the intermediate gamma-ray bursts
I. Horvath, Z. Bagoly, A. de Ugarte Postigo +2
One of the most important task of the Gamma-Ray Burst field is the classification of the bursts. Many researches have proven the existence of the third kind (intermediate duration)…
Dependence of the optical brightness on the gamma and X-ray properties of GRBs
L. G. Balázs, Z. Bagoly, I. Horvath +3
The Swift satellite made a real break through with measuring simultaneously the gamma X-ray and optical data of GRBs, effectively. Although, the satellite measures the gamma, X-ray…
Cosmology with Gamma-Ray Bursts Using k-correction
Andras Kovacs, Zsolt Bagoly, Lajos G. Balazs +2
In the case of Gamma-Ray Bursts with measured redshift, we can calculate the k-correction to get the fluence and energy that were actually produced in the comoving system of the GR…
GRB duration distribution considering the position of the Fermi
Dorottya Szecsi, Zsolt Bagoly, Istvan Horvath +3
The Fermi satellite has a particular motion during its flight which enables it to catch the gamma-ray bursts mostly well. The side-effect of this favourable feature is that the lig…
Detailed Classification of Swift's Gamma-Ray Bursts
I Horvath, Z Bagoly, LG Balazs +3
Earlier classification analyses found three types of gamma-ray bursts (short, long and intermediate in duration) in the BATSE sample. Recent works have shown that these three group…
SWIFT and BATSE bursts' classification
I. Horvath, Z. Bagoly, L. G. Balazs +2
Two classes of gamma-ray bursts were identified in the BATSE catalogs characterized by their durations. There were also some indications for the existence of a third type of gamma-…
Analysis of the Swift Gamma-Ray Bursts duration
I. Horvath, L. G. Balazs, Z. Bagoly +3
Two classes of gamma-ray bursts have been identified in the BATSE catalogs characterized by durations shorter and longer than about 2 seconds. There are, however, some indications…
Different satellites - different GRB redshift distributions?
Z. Bagoly, L. G. Balazs, I. Horvath +4
The measured redshifts of gamma-ray bursts (GRBs), which were first detected by the Swift satellite, seem to be bigger on average than the redshifts of GRBs detected by other satel…
