However, the time derivative of its spin-down rate differs markedly from that assumed for normal radio pulsars, meaning its actual age is uncertain.PSR J2004+3429 is a young pulsar with a characteristic age of ∼18 kyr. We currently rule out that PSR J2004+3429 is associated with near-by SNR G069.7+01.0, due to the high transverse velocity required to place the pulsar at its current position with respect to the remnant in the time-scale suggested by its characteristic age.a.

up to ∼100 kyr. PSR B1706−44 is recently detected in VHE gamma-rays (Hoppe et al. 2009), and it has largely extended X-ray emission (Romani et al. 2005).

There are some other PWNe with known large extended X-ray nebulae, such as PSR J1016−5857Within the boundaries of S147, a 143 ms pulsar PSR J0538+2817 was discovered by Anderson et al.
