Detection of two new RRATs at 111 MHz

TL;DR

This paper reports the discovery of two new rotating radio transients (RRATs) at 111 MHz, expanding understanding of transient radio sources with infrequent pulses, using observations from the LPA LPI radio telescope.

Contribution

First detection of two new RRATs at 111 MHz, providing new data on their dispersion measures, pulse widths, and periods, highlighting rare transient phenomena.

Findings

Discovered two RRATs with DM=21 and 35 pc/cm^3.

Pulse widths are 18 ms and 35 ms.

RRAT J2047+13 has an estimated period of 2.925 seconds.

Abstract

Two new rotating transients were detected in the 2020 observations carried out on the LPA LPI radio telescope. The dispersion measures of the found transients are DM=21 and 35 pc/cm^3, the pulse half-widths are We=18 and 35 ms for J1550+09 and J2047+13, respectively. The upper estimate of the period RRAT J2047+13 P=2.925s was obtained. The study shows the existence of rotating transients whose pulses appear less frequently than one pulse per 10 hours of observations.
