Spectral Cross-calibration of the Konus-Wind, the Suzaku/WAM, and the Swift/BAT Data using Gamma-Ray Bursts
gamma rays observations
2010/11/11
We report on the spectral cross-calibration results of the Konus-Wind, the Suzaku/WAM, and the Swift/BAT instruments using simultaneously observed gamma-ray bursts (GRBs). This is the first attempt to...
Cosmographic applications of Gamma Ray Bursts
Gamma rays bursts - Cosmology cosmological parameters - Cosmology distance scale
2010/11/11
In this work we present some applications about the use of the so-called Cosmography with GRBs. In particular, we try to calibrate the Amati relation by using the luminosity distance obtained from the...
Gamma Ray Bursts: basic facts and ideas
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
The recent years witnessed a dramatic improvement in our knowledge of the phenomenology and physics of Gamma Ray Bursts (GRBs). However, our "pillars of knowledge" remain a few, while many aspects rem...
Cosmological Constraints on the DGP braneworld model with Gamma-ray bursts
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/31
In this paper, we investigate observational constraints on the DGP model with the Gamma-ray bursts (GRBs) at high redshift obtained directly from the Union2 SNe Ia set.
A distinct peak-flux distribution of the third class of gamma-ray bursts: A possible signature of X-ray flashes?
High Energy Astrophysical Phenomena (astro-ph.HE) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
Gamma-ray bursts are the most luminous events in the Universe. Going beyond the short-long classification scheme we work in the context of three burst populations with the third group of intermediate ...
Duration distributions for different softness groups of gamma-ray bursts
High Energy Astrophysical Phenomena (astro-ph.HE) High Energy Physics - Phenomenology (hep-ph)
2010/12/27
Gamma-ray bursts (GRBs) are divided into two classes according to their durations. We investigate if the softness of bursts plays a role in the conventional classification of the objects.
Can past gamma-ray bursts explain both INTEGRAL and PAMELA/Fermi anomalies simultaneously?
Gamma ray bursts gamma-ray bursts
2010/3/9
Gamma-ray bursts (GRB) have been invoked to explain both the 511 keV emission from the galactic bulge and the high-energy positron excess inferred from the PAMELA and Fermi data. While independent exp...
Quark-Nova Explosion inside a Collapsar：Application to Gamma Ray Bursts
Quark-Nova Explosion Collapsar Gamma Ray Bursts
2009/9/4
If a quark-nova occurs inside a collapsar, the interaction between the quark-nova ejecta (relativistic iron-rich chunks) and the collapsar envelope leads to features indicative of those observed in Ga...
