The second pulsar, PSR J1814-1744, has P=3.975 s and P=7.4×10-13. These parameters imply τ c =85 kyr, and B=5.5×10 13 G, the largest of any known radio pulsar. Both PSR J1119-6127 and PSR J1814-1744 show apparently normal radio emission in a regime of magnetic field strength where some models predict that no emission should occur.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.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 ...Bs = 1.0×1012 G, and a characteristic age of 8.9 kyr. PSR J2022+3842 is thus the second-most ener-getic Galactic pulsar known, after the Crab, as well as the most rapidly-rotating young, radio-bright ... PSR J2022+3842 lacks a bright X-ray wind nebula and has an unusually low conversion efficiency of spin-down power to X-ray luminosity, LX/E ...

According to Thorsett et al. (2003), the age of the Monogem Ring from Sedov modeling is 86 kyr, which is consistent with 110 kyr, the characteristic spindown age of PSR B0656+14. They also showed ...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.The U.S. Department of Energy's Office of Scientific and Technical Information56033.3600, PSR J1826 1256 has a characteristic age of 14.4 kyr, spin-down luminosity E_ of 3:6 1036 erg s 1, and surface magnetic eld B= 3:7 1012 G (Kargaltsev et al.2017). XMM-Newton and Chandra X-ray observa-tions have characterized PSR J1826 1256 and the sur-rounding PWN (known as the Eel PWN;Roberts et al. 2007) in the X-ray band below 10 …result in a PWN age of 5 -10 kyr. However large overestimates may occur as the pulsar characteristic age is estimated assuming that the initial spin period is negligible (i.e. for high spin-down energy loss rate of pulsar); e.g. case of PSR J1400-6326 where true age is 1-2 kyr as compared to characteristic age of 12.7 kyr. Size and efficiency ...

We report on the X-ray emission properties of the pulsar PSR J1849-0001 and its wind nebula (PWN), as measured by Chandra, XMM-Newton, NICER, Swift, and NuSTAR. In the X-ray data, we detected the 38 ms pulsations of the pulsar up to ~60 keV with high significance. Additionally, we found that the pulsar's on-pulse spectral energy distribution displays significant curvature, peaking at ≈60 keV ...Jan 1, 2005 · The pulsar is very young, with a characteristic age τ c ≡ P / 2 P ˙ ∼ 5 kyr, and its spin-period of 16 ms makes it the fastest non-recycled pulsar known. PSR J0537−6910 is one of only a handful of young ( τ c < 10 kyr), energetic pulsars (of which the Crab pulsar is the prototype) that are known. ….

For PSR J1901+0658, the Shapiro delay would be only approximately 0.1 ms for a very edge-on orbit (sin ⁡ i = 0.999 𝑖 0.999 \sin{i}=0.999 roman_sin italic_i = 0.999). Good luck is needed for measuring the Shapiro delay of this weak pulsar over the 14.5-day orbit because the current TOA uncertainties measured by FAST are in the range of 0.03 ...HESS J1928+181 is the H.E.S.S. detection of HAWC J1928+178, a source of unknown astronomical origin. It may be associated with the middle-aged pulsar (82 kyr) PSR J1928+1746 ,, located 4.3 kpc away. It has been detected in radio wavelength and has a spin-down power of dE/dt = 1.6 × 10 36 erg s −1.Jun 17, 2021 · We report the discovery of an extended very-high-energy (VHE) gamma-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 8.2\sigma for E>25 ~TeV assuming a Gaussian template.

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.
