摘要：

We have discovered an extended X-ray feature, apparently associated with millisecond pulsar (MSP) PSR J1911-1114. The feature, which extends for similar to 1', was discovered from an XMM-Newton observation; the radio timing position of PSR J1911-1114 is in the midpoint of the feature. The orientation of the feature is similar to the proper motion direction of PSR J1911-1114. Its X-ray spectrum can be well-modeled by an absorbed power law with a photon index of Gamma = 1.8(-0.2)(+0.3). If this feature is confirmed to be a pulsar wind nebula (PWN), this will be the third case where an X-ray PWN has been found to be powered by a MSP.
