Further radio and X-ray timing studies of the pulsar led to determining a spin-down power of 2.2 ×1037 erg s−1 and a characteristic age of ∼10 kyr (Halpern et al.2001a). A compact PWN with a r∼100′′extension was detected in the radio band and was suggestedproduced by the birth supernova of PSR J1734-3333 could have already faded to undetectable brightness, estimates of which suggest timescales of 10-100 kyr. 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 betweenThe only plausible MWL counterpart associated with this emission is the energetic pulsar PSR J1813-1246 (Abdo et al. 2009), marginally coincident with the VHE best-fit centroid.

It coincides with an unresolved INTEGRAL source and the extended TeV source HESS J1837-069.

The U.S. Department of Energy's Office of Scientific and Technical InformationHESS 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 ...PSR J2021+3651 has a rotation period P = 104 ms and P_dot = 9.6x10^{-14}, implying a characteristic age ~17 kyr and a spin-down luminosity E_dot ~ 3.4x10^{36}ergs/s. The dispersion measure DM ~ 371 pc cm^{-3} is by far the highest of any observed pulsar in the Galactic longitude range 55 < l < 80.The survey has so far resulted in the discovery of 15 radio pulsars, including a pulsar with a characteristic age of ∼18 kyr, PSR J2004+3429, and a highly eccentric, binary millisecond pulsar ...

c = 42:9 kyr) rotation-powered pulsar (Gotthelf et al.2011;Kuiper & Hermsen 2015). The source exhibits a non-sinusoidal single pulse per rotation with width ˘0:5 in rotation phase at both ... PSR J1412+7922 and PSR J1849 0001 are only seen to be pulsed in X-rays, the timing models presented here will enable LIGO/Virgo to search for GWs from these two …2018). 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 measurement

Pulsars with true ages, often substituted by characteristic age, below tauc ∼100 kyr are considered young and ones with tau c ≥ 1 Myr are considered old, with the 'middle-aged' pulsars in the middle. ... in a 6.7 hr binary orbit, and PSR J1311-3430, an E = 4.9 x 1034 erg s-1 pulsar in an extreme 1.6 hr binary orbit. PSR J1446-4701 turned ...

3.1 PSR B0154+61 (J0157+6212, τ=200 kyr) Although data on PSR B0154+61 have been collected at Jodrell Bank for more than 10 yr since MJD 46866, this pulsar suffered its first observed glitch near MJD 48504. The glitch was quite small with the size of the frequency jump equal to 2.46 × 10 −9. The frequency and timing residuals are shown in lower and …

PSR B1509-58 ! Young pulsars, e.g. Crab, PSR 1509-58 reach maximum luminosity below 100 MeV ! Middle-aged Vela and older pulsars reach max. luminosity at GeV energies ! High-energy spectra of young pulsars are different from spectra of older γ-ray pulsars: L X/L γ larger for young pulsars!

PSR J1023-5746 has the smallest characteristic age (τ c = 4.6 kyr) and is the most energetic (\dot{E} = 1.1 × 10^{37} erg s -1 ) of all γ-ray pulsars discovered so far in blind searches. By analyzing &gt;100 ks of publicly available archival Chandra X-ray data, we have identified the likely counterpart of PSR J1023-5746 as a faint, highly ...
