Detection of diffuse TeV gamma-ray emission from the neaby
We report the TeV gamma-ray observations of the nearby normal spiral galaxy NGC 253. At a distance of ∼2.5 Mpc, NGC 253 is one of the nearest starburst galaxies. This relative closeness, coupled with the high star formation rate in the galaxy, make it a good candidate TeV gamma-ray source. Observations were carried out in 2000 and 2001 with the CANGAROO-II 10m imaging atmospheric Cerenkov teles...
متن کاملCorrelation between the X-ray and Tev Gamma Ray Emission from an Accreting X-ray Binary
Measurements of the signal strength of TeV gamma rays from the accreting X-ray binary Cen X-3 show evidence for correlation with both the RXTE/ASM and the BATSE X-ray signal strengths. There are indications that the time scale for the variability of the gamma rays may be similar to that of X-rays and as short as a day. These features of the X-ray and TeV emission from an accreting binary show m...
متن کاملEvidence for long-term Gamma-ray and X-ray variability from the unidentified TeV source HESS J0632+057
HESS J0632+057 is one of only two unidentified very-high-energy gamma-ray sources which appear to be point-like within experimental resolution. It is possibly associated with the massive Be star MWC 148 and has been suggested to resemble known TeV binary systems like LS I +61 303 or LS 5039. HESS J0632+057 was observed by VERITAS for 31 hours in 2006, 2008 and 2009. During these observations, n...
متن کاملGeV-TeV and X-ray flares from gamma-ray bursts
The recent detection of delayed X-ray flares during the afterglow phase of gamma-ray bursts (GRBs) suggests an inner-engine origin, at radii inside the deceleration radius characterizing the beginning of the forward shock afterglow emission. Given the observed temporal overlapping between the flares and afterglows, there must be inverse Compton (IC) emission arising from such flare photons scat...
متن کاملMagic Observations of the Unidentified Γ-ray Source Tev
We observed the first known very high energy (VHE) γ-ray emitting unidentified source, TeV J2032+4130, for 94 hours with the MAGIC telescope. The source was detected with a significance of 5.6σ. The flux, position, and angular extension are compatible with the previous ones measured by the HEGRA telescope system five years ago. The integral flux amounts to (4.5±0.3stat±0.35sys)×10 −13 ph cm s a...
