This and other considerations lead us to conclude that ...PSR J1048-5832 is a Vela-like (P=123.6 ms; tau~20.3 kyr) gamma-ray pulsar detected by Fermi, at a distance of ~2.7 kpc and with a rotational energy loss rate dot{E}_{SD} ~2 x 10^{36} erg/s. The PSR J1048-5832 field has been observed with the VLT in the V and R bands.

young pulsar PSR J1813-1749 located close to the center of supernova remnant G12.82-.02 (Gotthelf & Halpern 2009). PSR J1813-1749 has a spindown luminosity E-dot of 6.8 10e37 erg s−1, a characteristic age of 3.3-7.5 kyr (Gotthelf & Halpern 2009), and an estimated distance of 4.8 kpc (Halpern et al. 2012). Closer to the measured HAWC ...HESS J1825-137 is one of the most powerful and luminous TeV gamma-ray pulsar wind nebulae (PWNe), making it an excellent laboratory to study particle transportation around pulsars. We present a model of the (diffusive and advective) transport and radiative losses of electrons from the pulsar PSRJ1826-1334 powering HESSJ1825-137 using interstellar medium gas (ISM) data, soft photon fields and a ...This implies limits on the spin-down energy loss rate of \dot{E} < 2.3 \times 10^{35} erg s-1, the surface magnetic dipole field strength B s < 9.8 × 10 11 G, and the spin-down age τ c > 220 kyr. The latter is much longer than the SNR age, indicating that PSR J0821-4300 was born spinning near its present period. ….

However,no x-ray photons have been observed near the J1906+0746 radio position.[4]This also confirmed that there is no SNR around PSR J1906+0746. If PSR J1906+0746 were the product of an SN explosion of massive core,then it would be most likely to produce a detectable SNR born in such a short time(∼113 kyr)and a distance from 5 kpc to 10 kpc.The velocity and characteristic age of PSR J1825-1446 make it incompatible with SNR G016.8-01.1. There are no clear OB associations or SNRs crossing the past trajectory of PSR J1825-1446. We estimate the age of the pulsar to be 80-245 kyr, which is compatible with its characteristic age.

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). ... This and other considerations lead us to conclude that ...In the first instance, we assume that the age of PSR J0002+6216 is equal to its characteristic age (τ c = 306 kyr). In this case, our measured proper motion places the pulsar birthplace more than 2° away, well outside the boundaries of CTB 1. In this instance, there is no physical PSR–SNR association, just a line-of-sight coincidence.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.
