High-energy emission processes and long-duration behavior of Hessdalen lights

Characterize the processes responsible for high optical and radio-band energy output from Hessdalen luminous phenomena and determine the conditions under which such emissions persist for long durations.

Background

Observations at Hessdalen have documented luminous events that correlate with magnetic disturbances and exhibit intermittent radar signatures and VHF emissions, occasionally responding to laser illumination.

The authors explicitly identify unresolved questions about the origin and maintenance of high energy emissions across optical and radio bands, including why such emissions sometimes persist for extended durations.
