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 PSRJ1826-1334 powering HESSJ1825-137 using interstellar medium gas (ISM) data, soft photon fields and a ...The characteristic age of PSR J1734$-$3333 estimated from its current spin down rate implies that it is a young pulsar ($τ_c<10$ kyr). But the time derivative of its spin down rate differs markedly from that assumed for normal radio pulsars, meaning its actual age is uncertain. G354.8$-$0.8 is a supernova remnant (SNR) whose centre is located 21 arcmin away of the pulsar, and with a ...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 …

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).Abstract. During the search for counterparts of very-high-energy gamma-ray sources, we serendipitously discovered large, extended, low surface brightness emission from PWNe around pulsars with the ages up to ∼ similar-to \sim ∼ 100 kyrs, a discovery made possible by the low and stable background of the Suzaku X-ray satellite.

PSR J18131749 is located in the young (<3 kyr) supernova remnant G12.820.02 (Brogan et al.2005) at a distance d ˇ3 5 kpc (Messineo et al.2011). Observations at X-ray energies are crucial to the study of PSR J18131749. For example, the exceptional spatial re-solving power of Chandra allows an accurate measurementPSR J1024$-$0719 is a millisecond pulsar that was long thought to be isolated. However, puzzling results concerning its velocity, distance, and low rotational period derivative have led to reexamination of its properties. We present updated radio timing observations along with new and archival optical data that show PSR J1024$-$0719 is most likely in a long period (2$-$20 kyr) binary system ...

Very-high-energy $\\gamma$-ray emission provides constraints on the morphology and the physics mechanisms involved in the evolution of pulsar wind nebulae (PWNe). In the Galactic plane, around $312 ^{\\circ}$ of Galactic longitude, a promising region two-degree wide containing five powerful pulsars may offer a new insight on the transition between TeV-emitting PWNe and pulsar halos. Their ...The thresholds are 10 c s −1 for PSR J0537−6910, 4.5 c s −1 for PSR J1412+7922, and 5 c s −1 for PSR J1849−0001, and they are the same as previously used in Ho et al. for PSR J0537−6910 and in Bogdanov et al. for PSR J1412+7922 and PSR J1849−0001. Using these filtering criteria, we obtain clean data for pulse timing analysis.
