Effects of the background radiation on radio pulsar and supernova remnant searches and the birth rates of these objects
Abstract:In different directions of the Galaxy the Galactic background radio radiation and radiation of star formation regions which include a large number of OB associations have different influences on radio pulsar (PSR) and supernova remnant (SNR) searches. In this work we analyse the effects of these background radiations on the observations of PSRs at 1400 MHz and SNRs at 1000 MHz. In the interval l ?=?0?±?60 ° the PSRs with flux F 1400 ?>?0.2 mJy and the SNRs with surface brightness S?>?10 -21 W m -2 Hz -1 sr -1 are observable for all values of l and b up to distances of 6–7 kpc. All the SNRs with S?>?3?×?10 -22 Wm -2 Hz -1 sr -1 can be observed in the interval 60 ° ?
