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 J1016−5857For 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 ...We report on the setup and initial discoveries of the Northern High Time Resolution Universe survey for pulsars and fast transients, the first major pulsar survey conducted with the 100-m Effelsberg radio telescope and the first in 20 years to observe the whole northern sky at high radio frequencies.

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.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.In general, the rotation would exhibit irregularities for adolescence pulsars, which have characteristic ages less than ∼ 100 kyr. PSR J0940–5428 has a relatively lower characteristic age τ c ∼ 42.2 kyr and a similar period as Vela Pulsar, and, importantly, PSR J0940–5428 is a source of radio, X-ray and γ-ray radiations.

Despite extensive multi-frequency observations, only PSR J0106+4855 has detectable pulsations in the radio band. The other eight pulsars belong to the increasing population of radio-quiet gamma-ray pulsars.Abstract. 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 PSR J1826-1334 powering HESS J1825-137 using …Observations by the High-Altitude Water Cherenkov Observatory (HAWC) and Milagro have detected spatially extended TeV sources surrounding middle-aged (t ∼ 100-400 kyr) pulsars like Geminga and PSR B0656+14, which have been named "TeV halos," representing very extended TeV pulsar wind nebulae (PWNe) powered by relatively old pulsars. A few more HAWC-detected sources have been suggested to be ...The 10-kyr cycle can be considered as a half-precession cycle, while the 50-kyr cycle can be considered as a superposition of two precession cycles and one half-precession cycle, and thus the FeD curve is generally dominated by a precession cycle. Anyway, the dominant cycle of MS curve is very different from that of FeD curve in Madang profile.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.
