Fermi-LAT Observations of the Diffuse Gamma-Ray Emission: Implications for Cosmic Rays and the Interstellar Medium
Fermi-LAT Observations Diffuse Gamma-Ray Emission Implications Cosmic Rays the Interstellar Medium
2012/2/23
The gamma-ray sky >100 MeV is dominated by the diffuse emissions from interactions of cosmic rays with the interstellar gas and radiation fields of the Milky Way. Observations of these diffuse emissio...
Broad Line Radio Galaxies Observed with Fermi-LAT: The Origin of the GeV Gamma-Ray Emission
Broad Line Radio Galaxies Fermi-LAT:OriginGeV Gamma-Ray Emission
2011/10/10
We report on a detailed investigation of the gamma-ray emission from 18 broad line radio galaxies (BLRGs) based on two years of Fermi Large Area Telescope (LAT) data. We confirm the previously reporte...
Identification of gamma-ray emission from 3C345 and NRAO512
Galaxies: active - quasars: individual (3C 345, NRAO512, B3 1640+396) - Gamma rays: galaxies
2011/10/9
For more than 15 years, since the days of the Energetic Gamma-Ray Experiment Telescope (EGRET) on board the Compton Gamma-Ray Observatory (CGRO; 1991-2000), it has remained an open question why the pr...
Fermi Large Area Telescope Observations of the Active Galaxy 4C +55.17: Steady, Hard Gamma-Ray Emission and its Implications
Steady Hard Gamma-Ray Emission Implications
2011/9/29
We report Fermi/LAT observations and broad-band spectral modeling of the radio-loud active galaxy 4C +55.17 (z=0.896), formally classified as a flat-spectrum radio quasar. Using 19 months of all-sky s...
VHE gamma-ray Emission from Passive Supermassive Black Holes: Constraints for NGC 1399
Emission Passive Supermassive Black Holes
2011/9/28
Very high energy (VHE; >100 GeV) gamma-rays are expected to be emitted from the vicinity of super-massive black holes (SMBH), irrespective of their activity state. In the magnetosphere of rotating SMB...
An unified polar cap/striped wind model for pulsed radio and gamma-ray emission in pulsars
Pulsars general - Radiation mechanisms non-thermal - Gamma rays
2010/11/16
Thanks to the recent discovery by Fermi of about fifty new gamma-ray pulsars, it becomes possible to look for statistical properties of their pulsed high-energy emis-sion, especially their light-curve...
Search for gamma-ray emission from magnetars with the Fermi Large Area Telescope
stars magnetars X-rays stars
2010/11/9
We report on the search for 0.1{10 GeV emission from magnetars in 17 months of Fermi Large
Area Telescope (LAT) observations. No signi cant evidence for gamma-ray emission from any of the currently-k...
On the origin of variable gamma-ray emission from the Crab Nebula
ISM supernova remnants MHD shock waves gamma-rays theory radiation mechanisms non-thermal
2010/11/12
The oblique geometry of pulsar wind termination shock ensures that the Doppler beaming has a strong impact on the shock emission. We illustrate this using recent relativistic MHD simulations of the Cr...
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...
GEANT4 Simulations of Gamma-Ray Emission from Accelerated Particles in Solar Flares
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
Gamma-ray spectroscopy provides diagnostics of particle acceleration in solar flares, but care must be taken when interpreting the spectra due to effects of the angular distribution of the accelerated...
