X-ray observations have recently revealed a number of pulsar wind nebulae. The cases of PSRs J2124-3358 and J1509-5850 are particularly interesting. A highly asymmetic X-ray trail is found to be associated with PSR J2124-3358. This is the first time that extended X-ray emission from a solitary millisecond pulsar is detected. A radio feature is found to be elongated along the proper motion direction of this pulsar. In the second target of our proposal, PSR J1509-5850, a very long radio trail is found to be extended in the same direction as its X-ray counterpart. Moreover, there are 2 clumpy structures located along the trail. The one closer to the pulsar (~4' away) is identified as a SNR candidate MSC 319.9-0.7. It is exciting to probe whether the pulsar has any intrinsic relation to this SNR candidate and the origin of the trail. In order to study the morphological and photometric properties of these radio pulsar wind nebula candidates with high resolution imaging, we propose to observed these sources with ATCA. These studies will be conveyed in coordination with X-ray and gamma-ray observations.
