The Origin of Diffuse X-ray and γ-ray Emission from the Galactic Center Region: Cosmic Ray Particles
The inner couple hundred pcs of our Galaxy is characterized by significant amount of synchrotron-emitting gas, which appears to co-exist with a large reservoir of molecular gas. Many of the best studied sources in this region exhibit a mixture of 6.4 keV Fe Kα emission, molecular line emission and nonthermal radio continuum radiation. The spatial correlation between fluorescent Fe K-α line emis...
متن کاملGamma-Ray Emission from X-Ray Binaries
We summarize the current observational picture regarding high-energy emission from Galactic X-ray binaries, reviewing the results of the Compton Gamma Ray Observatory mission. We speculate on the prospects for the GLAST era.
متن کاملThe X-ray diffuse emission from the Galactic Center
A long BeppoSAX observation of the Galactic Center region shows that the spectrum of the diffuse X–ray emission from the SgrA Complex can be described with the sum of two thermal plasma models with temperatures of ∼0.6 keV and ∼89 keV. The spatial distribution of the diffuse emission is energy dependent. While the hard X–ray emission has a nearly symmetric distribution elongated along the Galac...
متن کاملX-ray and Gamma-ray Emission from Pulsar Magnetospheres
For polar-cap models based on electromagnetic cascades induced by curvature radiation of beam particles we calculate broad-band high-energy spectra of pulsed emission expected for classical (∼ 10 G) and millisecond pulsars (∼ 10 G). The spectra are a superposition of curvature and synchrotron radiation components and most of their detailed features depend significantly on the magnetic field str...
متن کاملThe Origin of X-ray Emission from a Galactic Center Molecular Cloud: Low Energy Cosmic Ray Electrons
The Galactic center region near l≈ 0.2 hosts a mixture of nonthermal linear filaments and thermal radio continuum features associated with the radio Arc. Chandra observations of this region reveal an X-ray filament and diffuse emission with an extent of roughly 60′′ × 2′′ and 5′ × 3′, respectively. The X-ray filament lies at the edge of the nonthermal radio filaments and a dense molecular shell...
