A Large Glitch in the Crab Pulsar
Chinese Journal of Astronomy and Astrophysics, 2001Using a new pulsar timing system at the 25-m radio telescope of Urumqi Astronomical Observatory, we have detected a large glitch in the Crab pulsar which occurred in 2000 July. The size of the glitch is Deltav/v similar to 2.4 x 10(-8), with a relative increment in frequency derivative Delta (v) overdot / (v) over dot similar to 5 x 10(-3).

X-ray Pulsar in the Crab Nebula
Science, 1969X-ray pulsations have been observed in the Crab Nebula at a frequency closely matching the radio and optical pulsations. About 5 percent of the total x-ray power of the nebula appears in the pulsed component. The x-ray pulsations have the form of a main pulse and an interpulse separated by about 12 milliseconds.

The Crab Nebula and its Pulsar
1990The Crab looks (presently) atypically slow because we only see its bright interior. The latter consists of (i) a thermal component, of temperature T ≳ 104 K, density n = 103.5 ± 0.5 cm-3, mass ≳ 1M⊙, and volume-filling factor f ≈ 10-3, composed of ≳ 104 filaments. The volume is filled by (ii) relativistic pair plasma, of energy distribution Nγ dγ ∼ γ-2.
