Pixel lensing is a technique used to search for baryonic components of dark matter (MACHOs) and allows detection of microlensing events even when the target galaxies are not resolved into individual stars. Potentially, it has the advantage of providing higher statistics than other methods but, unfortunately, traditional approaches to pixel lensing are very demanding in terms of computing time. We present the new, user friendly, tool MEDEA (Microlensing Experiment Data-Analysis Software for Events with Amplification). The package can be used either in a fully automatic or semi-automatic mode and can perform an on-line identification of events by means of a two level trigger and a quasi-on-line data analysis. The package will find application in the exploration of large databases as well as in the exploitation of specifically tailored future surveys.

Abstract

Pixel lensing is a technique used to search for baryonic components of dark matter (MACHOs) and allows detection of microlensing events even when the target galaxies are not resolved into individual stars. Potentially, it has the advantage of providing higher statistics than other methods but, unfortunately, traditional approaches to pixel lensing are very demanding in terms of computing time. We present the new, user friendly, tool MEDEA (Microlensing Experiment Data-Analysis Software for Events with Amplification). The package can be used either in a fully automatic or semi-automatic mode and can perform an on-line identification of events by means of a two level trigger and a quasi-on-line data analysis. The package will find application in the exploration of large databases as well as in the exploitation of specifically tailored future surveys.
