Description
Supermassive black holes can power some of the brightest and most energetic sources in the Universe. In Active Galactic Nuclei (AGNs), matter accreting onto the central black hole can launch relativistic jets whose emission is observed across the entire electromagnetic spectrum, from radio waves to gamma rays.
A useful way to visualize their broadband emission is through the characteristic two-hump shape of the spectral energy distribution, making some AGNs look like a "camel" in the sky.
In this talk, I will introduce how multiwavelength observations help us investigate the physical processes taking place in AGN jets, with a particular focus on the role of the Fermi-LAT space telescope in studying their gamma-ray emission.
