Search for radiation from the SNR G78.2+2.1: A test of the SNR theory of cosmic ray origin HEGRA collaboration
نویسندگان
چکیده
The SNR G78.2+2.1 is a prime candidate for VHE, UHE gamma emission because of its shock wave expanding into a molecular cloud thus forming the con guration of an accelerator and nearby target [1]. The HEGRA collaboration has made a detailed study of possible gamma emission using the wide angle air Cerenkov detector AIROBICC. The excellent angular resolution of AIROBICC allows for a scan for any structure in the vicinity of G78.2+2.1. Our upper ux limit remains a factor of 27 below a theoretical ux value, assuming certain plausible parameter values.

Search for Very High Energy Radiation from the Radio Bright Region Dr4 of the Snr G78.2+2.1
Data from the HEGRA air shower array are used to set an upper limit on the emission of-radiation above 25 (18) TeV from the direction of the radio bright region DR4 within the SNR G78.2+2.1 of 2.5 (7.1) 10 ?13 cm ?2 sec ?1. The shock front of SNR G78.2+2.1 probably recently overtook the molecular cloud Cong 8 which then acts as a target for the cosmic rays produced within the SNR, thus leading ...
متن کاملSearch for radiation above 20 TeV from supernova remnants in our galaxy HEGRA collaboration
It is generally assumed that supernova remnants are powerful cosmic accelerators and that they are most likely the origin of VHE and UHE cosmic radiation. The HEGRA collaboration reports on a systematic search for gamma radiation from all known supernova remnants smaller than 40 0 in the eld of view of the Cerenkov array AIROBICC.
متن کاملObservations of the supernova remnants Cas-A and Tycho with the HEGRA stereoscopic IACT system
Recently, young supernova remnants (SNR) from type Ia Supernovae (SNe) have become targets of interest for TeV gamma-ray astronomy. This prompted the HEGRA collaboration to extensively observe Tycho’s SNR in 1997 and 1998 with its stereoscopic IACT system. The HEGRA IACT system was also used to observe the young SNR Cas-A. Although considered to be the result of a SN type Ib, the detected stron...

متن کاملTeV Gamma Rays from Synchrotron X-ray SNR
Recent detections of both synchrotron X-ray and TeV gamma-ray emissions from several supernova remnants (SNR) are very exciting. SNR has been widely believed an unique candidate of cosmic-ray origin since the beginning of cosmic-ray physics, nevertheless little observational evidences have been reported so far. These detections are expected to be a clue of not only the galactic cosmicray origin...
