Absolute Timing of the Crab Pulsar with RXTE
We have monitored the phase of the main X-ray pulse of the Crab pulsar with the Rossi X-ray Timing Explorer (RXTE) for almost eight years, since the start of the mission in January 1996. The absolute time of RXTE’s clock is sufficiently accurate to allow this phase to be compared directly with the radio profile. Our monitoring observations of the pulsar took place bi-weekly (during the periods ...

متن کاملPulsar Timing
The motivation for radio pulsar timing and its basic principles are reviewed. Present and future radio timing techniques and hardware are summarised and compared. The array of present timing programmes and their scientific goals are collated and described. Recent results and future prospects are discussed, with emphasis on multi-wavelength techniques where appropriate. Timing of radio pulsars a...
متن کاملSpectroscopy of the Crab Pulsar
We present new, high signal-to-noise spectroscopy of the Crab Pulsar in the range λλ5000−7000 Å. The observations were carried out with the 6-meter telescope of the SAO with the spectrograph SP-124 with a resolution of 2 Å. After reduction of the Crab Nebula emission, the dereddened pulsar spectrum can be fitted by a power law with α = −0.15± 0.15. There are no lines (emission and absorption) w...
متن کاملHigh-Altitude Emission from Pulsar Slot Gaps: The Crab Pulsar
We present results of a 3D model of optical to γ-ray emission from the slot gap accelerator of a rotation-powered pulsar. Primary electrons accelerating to high-altitudes in the unscreened electric field of the slot gap reach radiationreaction limited Lorentz factors of ∼ 2× 10, while electron-positron pairs from lower-altitude cascades flow along field lines interior to the slot gap. The curva...
