Vla and Xmm - Newton Observations of Snr W 41 / Tev Γ - Ray Source Hess J 1834 - 087
The recently discovered extended TeV source HESS J1834-087 is associated with both a diffuse X-ray enhancement and a molecular cloud, projected at the center of an old radio supernova remnant G23.3-0.3 (SNR W41). New HI observations from the VLA Galactic Plane Survey (VGPS) show unambiguous structures associated with W41 in the radial velocity range of 53 to 63 km/s, so we obtain W41 distance o...
متن کاملObservation of VHE Gamma Radiation from HESS J1834-087/W41 with the MAGIC Telescope
Recently, the HESS array has reported the detection of γ-ray emission above a few hundred GeV from eight new sources located close to the Galactic Plane. The source HESS J1834-087 is spatially coincident with SNR G23.3-0.3 (W41). Here we present MAGIC observations of this source, resulting in the detection of a differential γ-ray flux consistent with a power law, described as Universität Würzbu...
متن کاملXMM - Newton observations reveal the X - ray counterpart of the very - high - energy γ - ray source HESS J 1640 – 465
We present X-ray observations of the as of yet unidentified very high-energy (VHE) γ-ray source HESSJ1640–465 with the aim of establishing a counterpart of this source in the keV energy range, and identifying the mechanism responsible for the VHE emission. The 21.8 ksec XMM-Newton observation of HESSJ1640– 465 in September 2005 represents a significant improvement in sensitivity and angular res...
متن کاملXMM – Newton observations of Soft Gamma - ray Repeaters
All the confirmed Soft Gamma-ray Repeaters have been observed with the EPIC instrument on the XMM– Newton satellite. We review the results obtained in these observations, providing the most accurate spectra on the persistent X-ray emission in the 1–10 keV range for these objects, and discuss them in the context of the magnetar interpretation.
متن کاملThe first XMM - Newton observations of the Soft Gamma - ray Repeater SGR 1900 + 14 1
A ∼50 ks XMM-Newton observation of SGR 1900+14 has been carried out in September 2005, after almost three years during which no bursts were detected from this soft gamma-ray repeater. The 0.8-10 keV spectrum was well fit by a power law plus blackbody model with photon index Γ=1.9±0.
