PSR J1856 0245 has a spin period of 81 ms, a characteristic age of 21 kyr, and a spin-down luminosity ergs s . It isE˙ p 4.6 #1036 1 positionally coincident with the TeV g-ray source HESS J1857 026, which has no other known counterparts. Young,

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 …Another video were romanization is inconstant to the last one? say it ain't so!The second pulsar, PSR J1814-1744, has P=3.975 s and P=7.4×10-13. These parameters imply τ c =85 kyr, and B=5.5×10 13 G, the largest of any known radio pulsar. Both PSR J1119-6127 and PSR J1814-1744 show apparently normal radio emission in a regime of magnetic field strength where some models predict that no emission should occur.Team KYR.

Occasionally, the "k" is shown in upper case, as in "100 Kyr"; this is an incorrect usage.

We present results of the timing observations of the 143 ms pulsar PSR J0538+2817 that provide a proper-motion measurement clearly showing an association of the pulsar with the supernova remnant S147. We measure a proper motion of 67 mas yr-1, implying a transverse velocity of v = 385 km s-1. We derive an age of the pulsar and S147 of only 30 ± 4 kyr, which is a factor of 20 times less than ...1. Introduction [2] All serious students of Earth's climate history have heard of the "100 kyr problem" of Milankovitch orbital theory, namely the lack of an obvious explanation of the dominant ∼100 kyr periodicity in climate records of the last 800,000 years. However, few have considered an equally perplexing characteristic of Earth's climate, one that similarly defies simple physical ...

We report the discovery of PSR J1906+0746, a young 144 ms pulsar in a highly relativistic 3.98 hr orbit with an eccentricity of 0.085 and expected gravitational wave coalescence time of ~300 Myr. The new pulsar was found during precursor survey observations with the Arecibo 1.4 GHz feed array system and retrospectively detected in the Parkes Multibeam plane pulsar survey data. From radio ...The associated pulsar, PSR J1849-0001, was found to have a spin-down luminosity Edot of 9.8 × 10e36 erg s-1 and a characteristic age Tchar of 42.9 kyr. The HGPS analysis confirms the existence of a source coincident with PSR J1849-0001. The best-fit position of HESS J1849-000 is located less than 0.03 deg from the X-ray pulsar position, well ...
