G343.1-2.3 and PSR 1706-44
The association of G343.1-2.3 and PSR 1706-44 has been controversial from its first proposal. In this paper we present new evidence from images made by with the Australia Telescope Compact Array (ATCA), MRT and Mt. Pleasant. To cover the full extent of G343.1-2.3 with ATCA mosaicing was required, and we present the polarisation images from this experiment. The ATCA observations confirms the muc...
متن کاملOn the association of G 343 . 1 - 2 . 3 and PSR 1706 - 44
The observations of the supernova remnant G343.1-2.3 with the Mauritius Radio Telescope, the Australia Compact Array, and the Hobart Single dish are presented. With these more sensitive measurements the association with the pulsar PSR1706-44 becomes much more likely. The major points from the observations are presented. .

We report on the detection of PSR 1706-44 in two ROSAT-PSPC observations. The recorded source counts are unpulsed with a 2 pulsed fraction upper limit of 18%. Spectral analysis did not distinguish between black-body and power law models; however, we argue that the lack of pulsations and the similarity in the pulsar's spin parameters to those of the Vela pulsar favour a power law model dN=dE / E...
متن کاملThe TeV gamma-ray emission mechanism of PSR 1706−44 based on the multi-wavelength spectrum
PSR 1706−44 has been observed at energies above several hundred GeV in 2000 and 2001 using the CANGAROO-II 10m telescope. Above 1TeV, the spectrum is a steep power-law, which is consistent with previous results. However, the spectral index seems to change around 1TeV and becomes much flatter at lower energies. In addition, we analyzed Chandra X-Ray Observatory (Chandra) archival data to derive ...
متن کاملSome arguments in support of the association of PSR B 1706 − 44 with the supernova remnant G 343 . 1 −
We present some arguments in support of the association of the pulsar PSR B 1706−44 with the supernova remnant G 343.1−2.3, based on the idea that these objects could be the result of a supernova explosion within a mushroom-like cavity (created by the supernova progenitor wind breaking out of the parent molecular cloud). We suggest that in addition to the known bright " half " of G 343.1−2.3 th...
