Search and Detection of Fast Radio Bursts in the Direction of Galaxies M31 and M33

Abstract

The results of processing of the data from the Big Scanning Antenna radio telescope of the Lebedev Physical Institute obtained from 2012 to 2019 for the purpose of searching for fast radio bursts in Galaxies M31 and M33 are presented. Using numerical simulation, a fixed-shape template was obtained, which was then used to separate the desired pulsed signal by convolution with a trial dispersion measure. As a result, from July 2012 to February 2019, nine fast radio bursts with various dispersion measures were detected, three of which were detected in the M33 direction with six pulses detected in the M31 direction. Pulse characteristics are presented.
