The pulsar's spin-down rate implies a rotation-powered luminosity E = 1.2 X 10(exp 38) erg/s, a surface dipole magnetic field strength B(sub S), = 1.0 X 10(exp 12) G, and a characteristic age of 8.9 kyr. PSR J2022+3842 is thus the second-most energetic Galactic pulsar known, after the Crab, as well as the most rapidly-rotating young, radio ...Cosmological redshift: sounds like the latest blockbuster coming to a theater near you, doesn't it?

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.For 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 ...

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 U.S. Department of Energy's Office of Scientific and Technical InformationWe report the discovery of 44.7 ms pulsations from the X-ray source CXOU J181335.1-174957 using data obtained with the XMM-Newton Observatory. PSR J1813-1749 lies near the center of the young radio supernova remnant G12.82-.02, which overlaps the compact TeV source HESS J1813-178. This rotation-powered pulsar is the second most energetic in the Galaxy, with a spin-down luminosity of \dot{E ...c > 220 kyr. The latter is much longer than the SNR age, indicating that PSR J0821−4300 was born spinning near its present period. Its properties are remarkably similar to those of the two other known CCO pulsars, demonstrating the existence of a class of neutron stars born with weak magnetic fields related to a slow original spin.We report the discovery and follow-up timing observations of two young energetic radio pulsars.

Abstract. PSR J0537 −--6910 is a young, energetic, rotation-powered X-ray pulsar with a spin period of 16 ms located in the Large Magellanic Cloud. We have searched for previously undetected radio pulsations (both giant and standard) from this pulsar in a 12-hour observation taken at 1400 MHz with the Parkes 64-m radio telescope.May 20, 2019 · The positive sloped gray lines indicate characteristic ages of 1 kyr, 100 kyr, 10 Myr, and 1 Gyr. The negative sloped gray lines correspond to inferred surface magnetic field strengths of 10 GG, 100 GG, 10 TG, and 100 TG. Magnetars (green), XDINSs (orange), RRATs (yellow), and the 8.5 s radio pulsar PSR J2144–3933 are indicated on the plot.PSR J1819−1458 has a spin period of P = 4.26 s, with a pulse detected roughly every three minutes in Parkes ob-servations above a flux density of S = 0.6 mJy at 1.4 GHz (McLaughlin et al. 2006).
