A Search for Fast Pulsars along the Galactic Plane
Abstract
We present results from a survey for fast pulsars at the Arecibo Observatory. Approximately 260 deg2 of sky were searched, primarily at Galactic latitude |b| <8°. Signals were sampled at intervals of 517 μs, allowing for the possibility of detecting pulsars with periods as short as 1 ms or less. Sensitivity varied as a function of sky position. In a typical direction, long-period pulsars with flux densities of order 0.9 mJy at 430 MHz could be detected, although sensitivity to the fastest pulsars was somewhat curtailed. Sixty-one pulsars were detected, 24 of which were previously unknown. Four of the pulsars, two newly discovered, have millisecond periods.
