PSR J2022+3842 is thus the second-most energetic Galactic pulsar known, after the Crab pulsar, as well as the most rapidly rotating ...Between 1.5 and 0.6 Myr ago, the period of the Earth's glacial cycles changed from 41 kyr, the period of the Earth's obliquity cycles, to 100 kyr, the period of the Earth's orbital eccentricity1,2 ...This and other considerations lead us to conclude that the pulsar is possibly older than 45 − 100 kyr. PSR J1734−3333 is a pulsar with rotational properties that place it between standard ...

Occasionally, the "k" is shown in upper case, as in "100 Kyr"; this is an incorrect usage.up to ∼100 kyr. PSR B1706−44 is recently detected in VHE gamma-rays (Hoppe et al. 2009), and it has largely extended X-ray emission (Romani et al. 2005). However, no X-ray observation covered the entire emission, and we could not measure the extension. There are some other PWNe with known large extended X-ray nebulae, such as PSR J1016−5857Introduction 3 • PSR J0359+5414 is a radio-quiet pulsar • Spin-down power . • Distance kpc. • Age = kyr. • The PWN associated to this source has been observed in X-rays with a arcsec size (Zyuzin et al. 2018). • Detected by Fermi-LAT • At VHE has not been detected before by any IACT or EAS experiment. • HAWC detects an excess above in the 15-78
In any case is clear that PSR J1119[6127 is among the very youngest neutron stars known. Three other pulsars with characteristic ages under 2 kyr are known : the Crab pulsar (q \ 1.3 kyr), PSR B1509[58 c No. 1, 2000 TWO HIGH MAGNETIC FIELD RADIO PULSARS in G320.4[1.2 (q \ 1.6 kyr), and PSR B0540[69 in the c Large Magellanic Cloud (q \ 1.7 kyr).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. Another possibility to explain the asymmetric pulse of ... ….
