Characteristics of Gamma-Ray Loud Blazars in the VLBA Imaging and Polarimetry Survey
Gamma-Ray Loud Blazars the VLBA Imaging
2011/1/11
The radio properties of blazars detected by the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope have been observed as part of the VLBA Imaging and Polarimetry Survey (VIPS). Th...
Soft Gamma-ray Detector for the ASTRO-H Mission
Soft Gamma-ray Detector the ASTRO-H Mission
2011/1/10
ASTRO-H is the next generation JAXA X-ray satellite, intended to carry instruments with broad energy coverage and exquisite energy resolution. The Soft Gamma-ray Detector (SGD) is one of ASTRO-H instr...
Discovery and follow-up studies of the extended, off-plane, VHE gamma-ray source HESS J1507-622
follow-up studies off-plane VHE gamma-ray source HESS J1507-622
2011/1/10
Context: The detection of gamma-rays in the very-high-energy (VHE) range (100 GeV-100 TeV) offers the possibility of studying the parent population of ultrarelativistic particles found in astrophysica...
The present status of the GAMMA facility consisting of an enlarged surface EAS array (116 of 1 m^2 scintillation detectors) and underground muon carpet (150 m^2 detectors) is described. The recent re...
A possible approach to three-dimensional cosmic-ray propagation in the Galaxy IV. Electrons and electron-induced gamma-rays
three-dimensional cosmic-ray propagation the Galaxy IV. Electrons
2011/1/11
Based on the diffusion-halo model for cosmic-ray (CR) propagation, including stochastic reacceleration due to collisions with hydromagnetic turbulence, we study the behavior of the electron component ...
Multi-wavelength Observations of the Flaring Gamma-ray Blazar 3C 66A in 2008 October
BL Lacertae objects individual (3C 66A) — galaxies ctive —gamma rays observations
2010/11/10
The BL Lacertae object 3C 66A was detected in a flaring state by the Fermi Large Area Telescope (LAT) and VERITAS in 2008 October. In addition to these gamma-ray observations, F-GAMMA, GASP-WEBT, PAIR...
The first gamma-ray outburst of a Narrow-Line Seyfert 1 Galaxy: the case of PMN J0948+0022 in July 2010
gamma-ray outburst Narrow-Line Seyfert 1 Galaxy
2011/1/10
We report on a multiwavelength campaign on the radio-loud Narrow-Line Seyfert 1 (NLS1) Galaxy PMN J0948+0022 (z=0.5846) performed in 2010 July-September and triggered by a high-energy gamma-ray outbur...
Evidence for gamma-ray emission from the low-mass X-ray binary system FIRST J102347.6+003841
gamma-ray emission the low-mass X-ray binary system
2011/1/10
The low-mass X-ray binary (LMXB) system FIRST J102347.6+003841 hosts a newly born millisecond pulsar (MSP) PSR J1023+0038 that was revealed as the first and only known rotation-powered MSP in a quiesc...
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.

Cosmological Evolution Blazars Extragalactic Gamma-Ray Background
2010/3/8
The latest determination of the extragalactic gamma-ray background (EGRB) radiation by Fermi is compared with the theoretical prediction of the blazar component by Inoue & Totani (2009; hereafter IT09...
