چکیده
Observation by the CANGAROO-III stereoscopic system of the Imaging Cherenkov Telescope has detected extended emission of TeV gamma rays in the vicinity of the pulsar PSR B1706−44. The strength of the signal observed as gamma-ray-like events varies when we apply different ways of emulating background events. The reason for such uncertainties is argued in relevance to gamma-rays embedded in the “off-source data”, that is, unknown sources and diffuse emission in the Galactic plane, namely, the existence of a complex structure of TeV gamma-ray emission around PSR B1706−44. Subject headings: gamma rays: observation — pulsar: individual (PSR B1706-44) — diffuse radiation

ICRC 2001 The CANGAROO - III Project : Status report
We report on the status of the construction of an array of four 10 m atmospheric Cherenkov telescopes for gamma-ray astronomy, near Woomera, in South Australia – the CANGAROO-III project. The first telescope of this array is the upgraded version of the CANGAROO-II 7 m telescope and has been in operation since March 2000. The second telescope, an improved version of the first, is being construct...
متن کاملReanalysis of Data Taken by the Cangaroo 3.8 Meter Imaging Atmospheric Cherenkov Telescope: Psr B1706–44, Sn 1006, and Vela
We have reanalyzed data from observations of PSR B1706–44, SN 1006, and the Vela pulsar region made with the CANGAROO 3.8m Imaging Atmospheric Cherenkov Telescope between 1993 and 1998 in response to the results reported for these sources by the H.E.S.S. Collaboration. Although detections of TeV gamma-ray emission from these sources were claimed by CANGAROO more than 10 years ago, upper limits ...
متن کاملOBSERVATIONS OF PULSARS , PSR 1509 − 58 AND PSR 1259 − 63 , BY CANGAROO 3 . 8 m TELESCOPE
The data for VHE (∼TeV) gamma rays from young gamma-ray pulsar PSR1509-58 observed in 1996 with the CANGAROO 3.8mČerenkov imaging telescope are presented, as well as the additional data from March to June of 1997. The high spin-down luminosity of the pulsar and the plerionic feature around the pulsar observed with radio and X-rays suggest that VHE gamma-ray emission is quite likely above the se...
متن کاملSearch for gamma - rays above 10 TeV from Markarian 421 in a high state with the CANGAROO - II telescope
A preliminary result from Markarian 421 observations in the energy region above 10 TeV with the CANGAROO-II 10 m telescope is presented. In January 2001, the HEGRA group reported that Markarian 421 had become very active, with flux levels up to 4 times that of the Crab Nebula. As a result, we observed Mkn 421 during six nights from Jan-uary 24th to February 1st, and four nights from March 1st t...
متن کاملCangaroo-iii Search for Gamma Rays from Sn 1987a and the Surrounding Field
Optical images of SN 1987A show a triple ring structure. The inner (dust) ring has recently increased in brightness and in the number of hot spots suggesting that the supernova shock wave has collided with the dense pre-existing circumstellar medium, a scenario supported by radio and X-ray observations. Such a shocked environment is widely expected to result in the acceleration of charged parti...
