These spin parameters imply a characteristic age c ¼ 4:8 kyr and a spin-down luminosity E˙ ¼ 3:3 ; 1037 ergs s 1, ... G21.5-0.9 and PSR J1833 1034 are much younger than c and likely their true age is P1000 yr. In that case, the initial spin period of the pulsar wask55 ms.PSR J1747-2958 is a young (tau=26 kyr), energetic (Edot=2.5x10^36 erg/s) supersonic pulsar at an estimated distance d=5 kpc. It powers the Mouse pulsar wind nebula (PWN; G359.23-.82), which ...c ≡ P/2P˙ ∼ 5 kyr, and its spin-period of 16 ms makes it the fastest non-recycled pulsar known. PSR J0537−6910is one of only a handful of young (τ c < 10 kyr), energetic pulsars (of which the Crab pulsar is the prototype) that are known. No radio pulsations were detected in a search [4] conducted soon after its discovery in X-rays.a. X-ray emission towards PSR J1826−1256 in the 1-7 keV energy band. Cyan contours correspond to 9.5, 10.5, and 12 counts/pixel. The position of the pulsar is indicated with a plus sign.

STUDY NOTES: Stable isotope (dD, d18O) data and site and source temperature reconstructions from the Dome Fuji 1st and 2nd ice cores for the past 720 kyr. ABSTRACT SUPPLIED BY ORIGINATOR: The dD temperature proxy in Antarctic ice cores varies in parallel with CO2 through glacial cycles.We discuss PSR J1740 + 1000, one of five pulsars recently discovered in a search of 470 deg at 430 MHz during the upgrade of the 305 m Arecibo Telescope. The period P = 154 ms and period derivative P = 2.1 x 10(exp -14) s s(exp -1) imply a spin-down age tau(sub s) = P/2P = 114 kyr that is smaller than 95% of all known pulsars. The youth and proximity of this pulsar make it a good candidate for ...SNR ∼1-7 kyr). PSR J1844−0256 was discovered in a search of AXP AX J1845−0258. Its P = 273 ms and DM = 820 pc cm−3 with a large scattering tail (τ scat ∼40 ms). The period derivative obtained from observations taken a year apart indicates that the pulsar is much older (τ c ∼300 kyr) than the target AXP (τ AXP ∼<10gamma-ray source around the location of the middle-aged (207.8 kyr) pulsar PSR J0622+3749 with the Large High Altitude Air Shower Observatory (LHAASO). - The source is detected with a significance of 8.2σ for E > 25 TeV assuming a Gaussian template."

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.PSR J1809-1917 is a young (τ = 51 kyr) energetic ( erg s⁻¹) radio pulsar powering a pulsar wind nebula (PWN).

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

We report the discovery of 44.7 ms pulsations from the X-ray source CXOU J181335.1-174957 using data obtained with the XMM-Newton Observatory. PSR J1813-1749 lies near the center of the young radio supernova remnant G12.82-.02, which overlaps the compact TeV source HESS J1813-178.
