Five pulsars are associated with sources included in the LAT bright gamma-ray source list, but only one, PSR J1413-6205, is clearly associated with an EGRET source. PSR J1023-5746 has the smallest characteristic age (tau_c=4.6 kyr) and is the most energetic (Edot=1.1E37 erg/s) of all gamma-ray pulsars discovered so far in blind searches.The characteristic age of PSR J1734−3333 estimated from its current spin down rate implies that it is a young pulsar (τc = 8.1 kyr). However, the time derivative of its spin-down rate differs markedly from that assumed for normal radio pulsars, meaning its actual age is uncertain.nebula (PWN) for PSR J1932+1916, which is one of the youngest (τc ≈ 35.4 kyr) pulsars from the Einstein@Home sample (Karpova et al. 2017). The X-ray data allowed us to constrain the distance to the pulsar and to suggest its pos-sible association with the supernova remnant (SNR) G54.4- 0.3. Here we report the results of search for X-ray coun-psr=V psr 39 kyr). Both systems are clearly brightened at radio wavelengths near the position of the pulsar, and it has been suggested that the associated pulsar wind is rejuvenating the radio emission from the SNR shell by the injection of fresh relativistic elec-trons (Shull et al. 1989). In this paper we will investigate the

The spin evolution of PSR J1734−3333 during the last 13.5 years is consistent with a braking index n = 0.9 ± 0.2, which corresponds to a systematic movement in the P– diagram with a slope of at least +0.9, arriving within the region of the magnetars after about 30 kyr. We discussed that secular evolution of the magnetic-dipole inclination ...For instance, an asymmetric pulse with a shape similar to the observed one could be produced by a polar cap whose trailing edge is hotter (hence brighter) than the leading edge, as was suggested by McGowan et al. to explain a similar pulse shape for the young (τ = 30 kyr) PSR J0538+2817.
