Jets from Radio Pulsars
The observational evidence for jets and phenomena arising from rotation powered radio pulsars is reviewed, including many recent and exciting discoveries at X-ray wavelengths. The well studied jets of the Crab pulsar are summarised, including recent results from the HST. The evolutionary links between the known binary radio pulsars and jets sources in X-ray binaries are discussed.
متن کاملBeaming matter waves from a subwavelength aperture
We show theoretically that the shape of a beam of matter waves cold atoms emerging from one subwavelength aperture pierced in a film can be collimated within a few degrees. By means of an external laser field, a potential well for the atoms in the direction perpendicular to the surface is created. In this way, a running surface matter wave can be excited when atoms diffract from the aperture. I...
متن کاملKinematics of Radio Pulsars
A very good fraction of stars in the sky are believed to be in binary (or multiple) systems. Therefore, we expect a good fraction of pulsars to have originated in binary systems. However, observations of pulsars have shown that most of the pulsars are not in binary system now. This would imply that these pulsars must have become solitary after the disruption of their progenitor binary system du...
متن کاملGravitation wave emission from radio pulsars revisited
We report a new pulsar population synthesis based on Monte Carlo techniques, aiming to estimate the contribution of galactic radio pulsars to the continuous gravitational wave emission. Assuming that the rotation periods of pulsars at birth have a Gaussian distribution, we find that the average initial period is 290 ms. The number of objects with periods equal to or less than 0.4 s, and therefo...
متن کاملSearching for gravitational waves from known pulsars
We present upper limits on the amplitude of gravitational waves from 28 isolated pulsars using data from the second science run of LIGO. The results are also expressed as a constraint on the pulsars’ equatorial ellipticities. We discuss a new way of presenting such ellipticity upper limits that takes account of the uncertainties of the pulsar moment of inertia. We also extend our previous metho...
