Description
PKS 1510-089 is a blazar located at a redshift of z=0.361. It belongs to the blazar class of flat spectrum radio quasar (FSRQ) and is one of the few FSRQs detected at very high energy (VHE) gamma-rays with Cherenkov telescopes. In July 2019, it underwent a flare in high energy (HE) gamma-rays as seen with Fermi-LAT. The source was detected by H.E.S.S. (High Energy Stereoscopic System) during the flare and data analysis reveals fast intra-night variability in the VHE band as well as complex multiwavelength spectral behavior.
These characteristics make the flare an excellent laboratory to probe the physical conditions in the emitting region and the properties of the particle distribution within the jet.
In this contribution, I will present the observational campaign, together with a time-dependent leptonic model of the flare, implemented with the AM3 framework, which allows us to follow the evolution of the underlying electron population in detail.
