A Viscous Heating Mechanism for the Hot Plasma in the Galactic Center Region
In addition to lines originating in a soft phase at ∼ 0.8 keV and to cold molecular clouds, the X-ray spectra from the Galactic center region also exhibit properties similar to those of a diffuse, thin, very hot plasma at 8 keV on a scale of hundreds of parsecs. This phase is surprising for more than one reason. First, such a hot plasma should not be bound to the Galactic plane and the power ne...
متن کاملAnnihilation Fountain in the Galactic Center Region
Two different model-independent mapping techniques have been applied to CGRO OSSE, SMM, TGRS and balloon data and reveal a feature in the 0.511 MeV e +-e − annihilation radiation pattern of our galaxy centered at ℓ ∼ −2 • and b ∼ 10 • with a flux of ∼ 5 · 10 −4 0.511 MeV ph cm −2 s −1. If near the galactic center, then e + sources are producing ∼ 10 42 e + s −1 which annihilate ≈ 1-2 kpc above ...
متن کاملWFC monitoring of the Galactic Center region
We review the results obtained with the Galactic center campaigns of the BeppoSAXWide Field X-ray Cameras (WFCs). This pertains to the study of luminous low-mass X-ray binaries (LMXBs). When pointed at the Galactic center, the WFC field of view contains more than half of the Galactic LMXB population. The results exemplify the excellent WFC capability to detect brief X-ray transients. Firstly, t...
متن کاملImplications for the Scattering Region in the Galactic Center
G359.87+0.18 is an enigmatic object located 15 from Sgr A. It has been variously classified as an extragalactic source, Galactic jet source, and young supernova remnant. We present new observations of G359.87+0.18 between 0.33 and 15 GHz and an H I absorption spectrum and use these to argue that this source is an Faranoff-Riley II radio galaxy. We are able to place a crude limit on its redshift...
