The second decametre pulsar census at UTR-2 radio telescope

Abstract

Our paper presents the results of the second census of pulsars in decametre wave range at UTR-2 radio telescope. Over the past ten years, the number of discovered nearby pulsars in the world has doubled, which has made it urgent to search for a low-frequency radio emission from newly discovered sources. To increase this census sensitivity, the integration time was doubled compared with the first census of 2010-2013. As a result, the decametre radio emission of 20 pulsars was detected, their flux densities and the shape of pulses were obtained. The dispersion measure for 10 pulsars and the rotation period for 8 pulsars were refined. For several pulsars the scattering time constant and FWHM were estimated in decametre wave range. Upper limits of flux densities of 102 not yet detected pulsars were also estimated.
