Latest results from the POINT-AGAPE pixel-lensing survey of the Andromeda Galaxy

Abstract

I report on recent results from the POINT-AGAPE pixel-lensing experiment, which is engaged in a search towards the Andromeda galaxy (M31) for gravitational microlensing signatures from massive compact halo objects (Machos). An analysis of two years of data reveals over 360 light-curves compatible with microlensing. The third year of data, currently being analysed, will be crucial in determining how many of these candidates are long-period variables rather than microlensing. Within the dataset we have isolated a subset of four high signal-to-noise ratio, short duration events which are compelling microlensing candidates. The properties and possible origins of these events are discussed.
