Extended emission is detected with H.E.S.S. (High Energy Stereoscopic System) in their vicinity, notably around the pulsar PSR J1413-6205.PSR J2139+4716 has the lowest spin-down power (3 × 10 33 erg s -1 ) among all non-recycled gamma-ray pulsars ever found. Despite extensive multi-frequency observations, only PSR J0106+4855 has detectable pulsations in the radio band. The other eight pulsars belong to the increasing population of radio-quiet gamma-ray pulsars.Abstract: The characteristic age of PSR J1734$-$3333 estimated from its current spin down rate implies that it is a young pulsar ($\tau_c<10$ kyr). But the time derivative of its spin down rate differs markedly from that assumed for normal radio pulsars, meaning its actual age is uncertain.W44 hosts the pulsar PSR B1853+01, a 20 kyr pulsar with dE/dt= 4.3 × 10 35 erg s −1 located ∼3 kpc away. W44 has not been detected by H.E.S.S. during the HGPS, but …

The second pulsar, PSR J1814-1744, has P=3.975 s and P=7.4×10-13. These parameters imply τ c =85 kyr, and B=5.5×10 13 G, the largest of any known radio pulsar. Both PSR J1119-6127 and PSR J1814-1744 show apparently normal radio emission in a regime of magnetic field strength where some models predict that no emission should occur.Pulsar research at soft g -rays. s.
