Search for rotating radio transients in monitoring data for three years

TL;DR

This study conducted a three-year search for rotating radio transients at 111 MHz using the LPA telescope, discovering 19 new RRATs, including some among the closest known to Earth, and estimating periods for a few.

Contribution

It reports the discovery of 19 new RRATs and period estimates for three, expanding the known population and characteristics of RRATs at low frequencies.

Findings

Discovered 19 new RRATs at 111 MHz.

Estimated periods for three RRATs.

Identified two RRATs as among the closest to Earth.

Abstract

The search for rotating radio transients (RRAT) was done at a frequency of 111 MHz, in daily observations carried out on the radio telescope, a Large Phased Array (LPA) at declinations -9o < decj < +42o. 19 new RRATs were discovered for dispersion measures (DM) from 2.5 to 72.6 pc cm^{-3}. Estimates of the periods were obtained for three RRATs. Two of them (J0408+28; J0440+35) are located at distances of 134 and 136 pc from Sun and are among the closest of all known RRATs.
