Abstract content

Current point source searches mostly apply only the direction of the reconstructed event; furthermore, they reduce available information by grouping events into sky bins. In this analysis we use a search based on maximum likelihood techniques, utilizing both event direction and energy, to enhance our ability to detect point sources. Especially, use of energy information allows us to fit the spectral index of a hypothetical source along with flux. This method improves both sensitivity and discovery potential of the AMANDA-II array significantly. The method can naturally be applied to IceCube and allows superposition of data from detectors with different sensitivity and angular resolution, such as the IceCube array which changes and improves with each season of construction.
