A Fermi-LAT view of the sky below 100 MeV
Résumé
The Large Area Telescope (LAT) collaboration has recently completed the development of the "Pass 8" event-level analysis that provides a comprehensive revision of the algorithms used for event reconstruction and particle identification. Among other performance improvements, Pass 8 provides a drastic increase in the effective area of the LAT instrument below 100 MeV. Together with a better modelling of the instrument’s energy response function, Pass 8 gives us the opportunity to look with the LAT at the largely unexplored 10-100 MeV energy regime. In this proceeding we will summarize the main technical improvements and show preliminary science results obtained below 100 MeV
