摘要

摘要对普什奇诺射电天文台新发现的三颗脉冲星的射电辐射进行了分析。采用大型相控阵和总带宽为2.245 MHz、时间分辨率为2.46或5.12 ms的标准数字接收机，在111 MHz的频率上进行了详细的观测。在J0220+3622中观测到亚脉冲漂移，在J0303+2248中观测到耀斑活动，在J0810+3725中观测到零化现象。

Peculiarities of radio emission from new pulsars at 111 MHz

Abstract The analysis of radio emission of three new pulsars discovered at the Pushchino Radio Astronomy Observatory is presented. The detailed observations were carried out at a frequency of 111 MHz using the large phase array and the standard digital receiver with a total bandwidth of 2.245 MHz and a time resolution of 2.46 or 5.12 ms. All pulsars exhibit features of their radiation, the subpulse drift is observed in J0220+3622, the flare activity is exhibited in J0303+2248, and the nulling phenomenon has been detected in J0810+3725.
