Search for pulsars in the summed power spectra at a frequency of 111 MHz

Abstract

The search of pulsars in monitoring observations being carried out for 5 years using LPA LPI radio telescope was done in 96 spatial beams covering daily 17,000 square degrees. Five new pulsars were detected. Candidates into pulsars were selected in the summed power spectra. The use of a noise generator allowed to renormalize the data and to perform correct summing up of the power spectra for individual directions in the sky. Herewith, the sensitivity increased more than 20 times in comparison with individual sessions of observations. For pulsars with pulse durations greater than 100 ms at declinations +30o<dec.<+40o it is equal to 1.2 mJy and 0.4 mJy in/out of the Galaxy plane.
