Search for Weak Components in Pulsar Radiation

The search for weak components outside the main pulse (MP) in the radiation of pulsars at a frequency of 110 MHz observed on the LPA LPI telescope in the Pushchino Multibeam Pulsar Search (PUMPS) has been carried out. The sample included 96 pulsars, for which the signal-to-noise ratio ( $$S{\text{/}}N$$ ) in the main pulse of the average profile during accumulation over 10 years was more than 40. It has been found that PSR J1543+0929 has radiation for almost the entire period. The profile is three-component. The relative amplitudes of the lateral weak components are 0.013 and 0.025. For PSR J2234+2114, a precursor that is $$53^\circ $$ away from the MP has been detected.
