The large-scale cometary nebula of PSR B1706-44
Abstract
With a characteristic age of about 20 kyr, the Vela-like pulsar PSR B1706-44 powers an X-ray compact ( 3') X-ray nebula with an equatorial wind and polar jets. It is possibly associated with the partial radio shell of SNR G343.1-2.3. Recently, H.E.S.S. has detected hard and extended TeV emission from a region around a position significantly offset from the pulsar. In order to test for the hypothesis that the TeV emission is associated with the pulsar, we analyze both XMM-Newton and Chandra data and show the presence of a large-scale cometary nebula extending far ( 10') from the pulsar. We search for its signature in other wavelengths, we study its spectral characteristics and discuss the possible association with the TeV emission.
