Periodicities in an active region correlated with Type III radio bursts observed by Parker Solar Probe.

Context: Periodicities have frequently been reported across many wavelengths in the solar corona. Correlated periods of ~5 min, comparable to solar -modes, are suggestive of coupling between the photosphere and the corona.

Aims: Our study investigates whether there are correlations in the periodic behavior of Type III radio bursts which are indicative of nonthermal electron acceleration processes, and coronal extreme ultraviolet (EUV) emission used to assess heating and cooling in an active region when there are no large flares.
