The Fermi-LAT Lightcurve Repository

Michela Negro

The Fermi-LAT lightcurve repository (LCR) is a public library of gamma-ray lightcurves for 1525 Fermi-LAT sources deemed variable. The repository consists of lightcurves on timescales of days, weeks, and months, generated through a full-likelihood unbinned analysis of the source and surrounding region, providing flux and photon index measurements for each time interval. Hosted at NASA's FSSC, the library provides users with access to this continually updated light curve data, serving as a resource to the time-domain and multi-messenger communities, as well as a data collection optimal for population studies. Here I will present the main feature and potential expansions and use of the LCR.


This talk will be given in the Transients and Variable Stars (TVS) Science Collaboration session.
