Detection of 25 new rotating radio transients at 111 MHz

TL;DR

This study reports the detection of 25 new rotating radio transients (RRATs) at 111 MHz, doubling the known RRATs in the observed area and confirming several previously known sources through daily monitoring.

Contribution

The paper presents the first detection of 25 new RRATs at metre wavelengths, expanding the known population and providing new observational data on their properties.

Findings

Detected 25 new RRATs at 111 MHz.

Confirmed 7 previously known RRATs.

Doubled the total number of RRATs in the studied area.

Abstract

Nearly all fast radio RRAT-type transients that are pulsars with rare pulses have been previously detected using decimetre wavelengths. We present here 34 transients detected at metre wavelengths in our daily monitoring at declinations -9o < decl. < +42o. 25 transients are new RRATs. We confirmed the detection of 7 RRATs based on our early observations. One of the 34 detected transients was determined to be a new pulsar J1326+3346. At the same time, out of 35 RRATs detected at the decimetre wavelengths and included in the studied area, only one was detected by us J1848+1518. The periods of 6 RRATs were found from the time of arrival of single pulses. Three quarters of all RRATs were observed more than once and the total number of RRATs in the area studied has doubled.
