The contribution from blazar cascade emission to the extragalactic gamma-ray background: What a role does the extragalactic magnetic field play?
diffuse radiation galaxies active gamma rays general
2012/2/21
We estimate the contribution to the extragalactic gamma-ray background (EGRB) from both intrinsic and cascade emissions produced by blazars using a simple semi- analysis method for two models of the b...
The Role of Stochastic Re-acceleration in the Prompt Emission of Gamma-Ray Bursts: Application to Hadronic Injection
Stochastic Re-acceleration Prompt Emission Gamma-Ray Bursts: Application Hadronic Injection
2011/10/20
We study effects of particle re-acceleration in the post-shock region via magnetohydrodynamic/plasma turbulence, in the context of a mixed hadronic-leptonic model for the prompt emission of gamma-ray ...
A Detailed Study of the Molecular and Atomic Gas Toward the γ-ray SNR RX J1713.7-3946: Spatial TeV γ-ray and ISM Gas Correspondence

2011/9/27
RX J1713.7-3946 is the most remarkable TeV {\gamma}-ray SNR which emits {\gamma}-rays in the highest energy range 10-100 TeV. We made a combined analysis of CO and HI in the SNR and derived the total ...
Unveiling the nature of IGR J17177-3656 with X-ray, NIR and Radio observations
Unveiling IGR J17177-3656 X-ray NIR Radio observations
2011/9/26
We report on the first broad-band (1-200 keV) simultaneous Chandra-INTEGRAL observations of the recently discovered hard X-ray transient IGR J17177-3656 that took place on 2011, March 22, about two we...
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...
INFLUENCE OF SOLAR X-RAY FLARES ON THE EARTH-IONOSPHERE WAVEGUIDE

A simultaneous analysis of solar
are X-ray irradiance and VLF
signal amplitude on the GQD/22.1 kHz trace was carried out. Solar
are data were
taken from GOES 12 satellite listings. The VLF ampli...
