Description

Low-luminosity AGNs (LLAGNs) are super-massive black holes accreting at low, sub-Eddington rates (with Eddington ratio, L$_{bol}$/L$_{AGN} \leq 10^{-3}$). Despite occupying approximately 40% of the local Universe, these sources are less explored due to their faintness. Recent gamma-ray observations have revealed new insights into these sources. Utilizing data from the Fermi Gamma-ray Space Telescope, we perform comprehensive spectral energy distribution (SED) modeling to decipher the gamma-ray properties of LLAGNs.

Our study highlights the role of kiloparsec-scale jets in these systems, investigating gamma-ray emission through processes such as inverse Compton scattering of starlight (IC/starlight) photons. I will present a comparison between leptonic and hadronic models in the jets of LLAGNs and how these jets fit in the luminosity spectrum of AGN activity.
