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…
Redshifts of the Long Gamma-Ray Bursts
Z. Bagoly, I. Csabai, A. Meszaros +4
The low energy spectra of some gamma-ray bursts' show excess components beside the power-law dependence. The consequences of such a feature allows to estimate the gamma photometric…
Physical Difference between the short and long GRBs
L. G. Balazs, Z. Bagoly, I. Horvath +2
We provided separate bivariate log-normal distribution fits to the BATSE short and long burst samples using the durations and fluences. We show that these fits present an evidence…
Properties of the intermediate type of gamma-ray bursts
I. Horvath, F. Ryde, L. G. Balazs +2
Gamma-ray bursts can be divided into three groups ("short", "intermediate", "long") with respect to their durations. The third type of gamma-ray bursts - as known - has the interme…
A possible interrelation between the estimated luminosity distances and internal extinctions of type Ia supernovae
L. G. Balazs, Zs. Hetesi, Zs. Regaly +4
We studied the statistical properties of the luminosity distance and internal extinction data of type Ia supernovae in the lists published by Tonry et al. (2003) and Barris et al.…
Redshift distribution of gamma-ray bursts and star formation rate
A. Meszaros, Z. Bagoly, L. G. Balazs +1
The redshift distribution of gamma-ray bursts collected in the BATSE Catalog is compared with the star formation rate. We aim to clarify the accordance between them. We also study…
A new definition of the intermediate group of gamma-ray bursts
I. Horvath, L. G. Balazs, Z. Bagoly +2
Gamma-ray bursts can be divided into three groups ("short", "intermediate", "long") with respect to their durations. This classification is somewhat imprecise, since the subgroup o…
A Gamma-Ray Bursts' Fluence-Duration Correlation
Istvan Horvath, Lajos G. Balazs, Peter Meszaros +2
We present an analysis indicating that there is a correlation between the fluences and the durations of gamma-ray bursts, and provide arguments that this reflects a correlation bet…
Where is the 3rd subgroup of GRBs?
I. Horvath, A. Meszaros, L. G. Balazs +1
It is shown that in the duration-hardness plane the GRBs of the third intermediate subgroup are well defined. Their durations are intermediate (i.e. roughly between 2 and 10 second…
Likelihood Estimation of Gamma Ray Bursts Duration Distribution
Istvan Horvath
Two classes of Gamma Ray Bursts have been identified so far, characterized by T90 durations shorter and longer than approximately 2 seconds. It was shown that the BATSE 3B data all…
'On the difference between the short and long gamma-ray bursts'
L. G. Balazs, Z. Bagoly, I. Horvath +2
We argue that the distributions of both the intrinsic fluence and the intrinsic duration of the gamma-ray emission in gamma-ray bursts from the BATSE sample are well represented by…
Gamma photometric redshifts for long gamma-ray bursts
Z. Bagoly, I. Csabai, A. Mészáros +4
It is known that the soft tail of the gamma-ray bursts' spectra show excesses from the exact power-law dependence. In this article we show that this departure can be detected in th…
A Remarkable Angular Distribution of the Intermediate Subclass of Gamma-Ray Bursts
A. Meszaros, Z. Bagoly, I. Horvath +2
In the article a test is developed, which allows to test the null-hypothesis of the intrinsic randomness in the angular distribution of gamma-ray bursts collected at the Current BA…
An intrinsic anisotropy in the angular distribution of gamma-ray bursts
L. G. Balazs, A. Meszaros, I. Horvath +1
The anisotropy of the sky distribution of 2025 gamma-ray bursts (GRBs) collected in Current BATSE catalog is confirmed. It is shown that the quadrupole term being proportional to $…
Anisotropy of the sky distribution of gamma-ray bursts
L. G. Balazs, A. Meszaros, I. Horvath
The isotropy of gamma-ray bursts collected in Current BATSE catalog is studied. It is shown that the quadrupole term being proportional to is non-zero with a…
A 3rd Class of Gamma Ray Bursts?
I. Horvath
Two classes of Gamma Ray Bursts have been identified so far, characterized by T_90 durations shorter and longer than approximately 2 seconds. We show here that the BATSE 3B data al…
