Pulsar radio pulses are made up of the so called core and conal components. A remarkably precise relation for core component widths, found observationally, in effect specifies the size of the polar cap on pulsars. Inclusion ...

The astrophysical aspects of proposals of escape of supermassive blackholes from galactic nuclei and their implications in relation to quasars are discussed. We conclude that high velocity recoil of the central engine can ...

Propagation of photons in the spacetime exterior to a rapidly rotating neutron star is investigated, using a rotationally perturbed spherical metric, to determine the pulse profile of fast pulsars. We find that spacetime ...
