Discovery of the Radio and X-ray Counterpart of Tev Γ-ray Source Hess J1731-347
We discover a faint shell-type radio and X-ray source, G353.6-0.7, associated with HESS J1731-347. G353.6-0.7 is likely an old supernova remnant (SNR), based on radio (0.8 GHz, 1.4 GHz and 5 GHz), infrared (8 µm from the GLIMPSE Legacy Project and 21 µm from the Midcourse Space Experiment), and X-ray (0.1 keV-2.4 keV from the ROSAT survey and 5-20 keV from the INTEGRAL survey) data. The SNR, ce...
متن کاملCorrelation between the TeV γ-ray and X-ray emission from an accreting X-ray binary
The signal strength of TeV gamma rays from the accreting X-ray binary Cen X-3 shows evidence for correlation with both the RXTE/ASM and the BATSE X-ray signal strengths. The time scale for the variability of the gamma rays may be similar to that of X-rays and as short as a day.
متن کاملX - ray to TeV γ - ray broad band emitter
Within the sample of unidentified γ-ray sources found in the first survey of our Galaxy, AX J1838.0-065 is particularly interesting due to its likely physical association with the newly discovered TeV source HESS J1837-069 (Aharonian et al. 2005a). In fact, its position coincides with the center of gravity of the TeV emission and therefore has been suggested by Aharonian et al. (2005a) as the m...
متن کاملVla 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 کاملHard X-ray identification of η Carinae and steadiness close to periastron
Context. The colliding-wind binary η Carinae exhibits soft X-ray thermal emission that varies strongly around the periastron passage. It has been found to have non-thermal emission, thanks to its detection in hard X-rays using INTEGRAL and Suzaku, and also in γ-rays with AGILE and Fermi. Aims. This paper attempts to definitively identify η Carinae as the source of the hard X-ray emission, to ex...
