Abstract:  We present results from a survey for fast pulsars at the Arecibo Observatory. Approximately 260 square degrees of sky were searched, primarily at Galactic latitude jbj ! 8 ffi . Signals were sampled at intervals of 517 s, 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, twenty-four of which were previously unknown. Four of the pulsars, two newly discovered, have millisecond periods.

Introduction Over the past quarter century, large-scale surveys specifically designed to detect pulsed radio signals have proven to be a highly productive means of finding pulsars. While most of the sky has been sea...
