Abstract. We present the discovery and timing of the young (age ∼28.6 kyr) pulsar PSR J0837–2454. Based on its high latitude ( b = 98) and dispersion measure …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.The young (1{5 kyr) energetic pulsar PSR J0537−6910 (Wang & Gotthelf1998;Chen et al.2006) resides in the Large Magellanic Cloud at a distance of 49.6 kpc (Pietrzynski et al.2019). Its pulsations are only de-tectable at X-ray energies, and the pulsar was rst ob-2.1 PSR J0627+0706. With a characteristic age of only 250 kyr, PSR J0627+0706 is by far the most energetic object in this sample. 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.

Of the mode-switching pulsars in Table 1, the rotational and other properties of PSR B2021+51 are most comparable with PSR J0738-4042, especially the characteristic age. Liu et al. ( 2021b ) revealed that the presence of emission state switching phenomenon in PSR B2021+51 manifests itself in wider mean pulse profiles following a small glitch …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.

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 ∼<10

The timing solution, reported by Levin et al. , implies a very high surface magnetic field of B≈ 2.8 × 10 14 G and a characteristic age of τ c ≈ 4 kyr. PSR J1622-4950 has a flat radio spectrum and a highly variable flux density and pulse profile [8 - 10, 16, 89], which is similar to other radio magnetars.with an estimated characteristic age of 77 kyr2 and a spin-down 2 There is a significant discrepancy between the characteristic spin-down age of PSR J2021+4026 and the estimated age of SNR G 78.2+2.1 of <10 kyr (Leahy et al. 2013).

However, the time derivative of its spin-down rate differs markedly from that assumed for normal radio pulsars, meaning its actual age is uncertain.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.
