Search for Ultra--High-Energy Point-Source Emission over Various Timescales
Abstract
A method has been developed to search for pulsed and/or unpulsed ultra-high-energy (UHE) emission from point sources over a range of time scales. This method has been applied to data accumulated with the CYGNUS extensive air-shower array to search for episodic emission from Cyg X-3, Her X-1, the Crab Nebula, and a collection of 48 secondary source candidates. An examination of timescales ranging from minutes to years has yielded results consistent with background fluctuations.
