For the pulsar PSR J1734-3333, both the estimated SNR age (23 kyr) [35] and proper motion age (45-100 kyr) [94] are much older than its characteristic age (8.1 kyr), which might hint at the fact ...

Comparing independently derived pulsar velocities provides another consistency check on the association. At a distance of 2 ± 0.4 kpc and age 10 ± 0.2 kyr, the 28' ± 1' PSR-SNR offset predicts V PSR = 1600 ± 450 km s −1, where the uncertainty is calculated from the quadrature sum of the errors on age, distance, and angular offset.The characteristic age of PSR J1734−3333 estimated from its current spin down rate implies that it is a young pulsar (τ c = 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.PSR J1446-4701 turned out to be a non-eclipser with possibly low (face-on) orbital inclination, with emission from both the pulsar and the intra-binary shock observable throughout the binary orbit. PSR J1311-3430 is a known eclipser, in which hints of spectral variability have been found, between pulsar superior and inferior conjunction phases.In comparison to τ c , the 10-30 kyr age estimated for MSH 11-61A suggests that the pulsar was born in the SNR with initial period in the range 54 <= P 0 <= 60 ms. PSR J1101-6101 is the least energetic of the 15 rotation-powered pulsars detected by INTEGRAL, and has a high efficiency of hard X-ray radiation and jet power.

Three of these pulsars are in binary systems, consisting of a redback (PSR J2055+1545), a black widow (PSR J1630+3550), and a neutron star-white dwarf binary (PSR J2116+1345). The fourth MSP, PSR J2212+2450, is isolated.

We report the discovery of PSR J2022-<-3842, a 24 ms radio and X-ray pulsar in the supernova remnant G76.9+i.0, in observations with the Chandra X-ray telescope, the Robert C. Byrd Green Bank Radio Telescope, and the Rossi X-ray Timing Explorer (RXTE).

This object displays a prominent interpulse, suggesting an orthogonal rotator. It also has significant timing noise, which is typical of young pulsars. This is the reason for the large reduced χ 2 of its solution.

The distance and the age of the PWN were set at 3.2 kpc and 19.5 kyr respectively (Abdo et al. 2010), the same as that of PSR J1907+0602.

The characteristic age of PSR J1734$-$3333 estimated from its current spin down rate implies that it is a young pulsar ($τ_c<10$ kyr).
