Air Shower Radio Emission with Energy E$_0$$\geq$10$^{19}$ eV by Yakutsk Array Data

TL;DR

This paper reports on the Yakutsk Array's measurements of radio emissions from ultra-high-energy air showers exceeding 10^19 eV, including the highest energy event recorded at the site, using data from 1987-1989 and 2009-2014.

Contribution

It presents the first detection of radio emission from air showers with energies above 10^19 eV at Yakutsk, including the highest energy event observed there.

Findings

Radio emission detected from air showers > 10^19 eV

First observation of radio signals from ultra-high-energy showers at Yakutsk

Recorded the highest energy air shower at Yakutsk (~2×10^20 eV)

Abstract

The paper presents short technical description of Yakutsk Radio Array and some preliminary results obtained from measurements of radio emission at 32 MHz frequency induced by air shower particles with energy {\epsilon}$\geq$1$\cdot$10$^{19}$ eV. The data obtained at Yakutsk array in 1987-1989 (first set of measurements) and 2009-2014 (new set of measurements). For the first time, at Yakutsk array radio emission from air shower with energy > 10$^{19}$ eV was registered including the shower with highest energy ever registered at Yakutsk array with energy $\sim$2$\cdot$10$^{20}$ eV.
