Unraveling AGN Jet Emission from Radio to Gamma-rays

Active Galactic Nuclei (AGN) are powerful multiwavelength emitters, driven by accretion onto supermassive black holes and the launch of relativistic jets. While blazars provide a jet-aligned, Doppler-boosted perspective, misaligned AGNs (MAGNs), such as FR I/FR II radio galaxies and broad-line radio quasars, offer a less biased view of intrinsic jet properties and variability. In this talk, I will present recent multiwavelength studies of MAGNs, including time-resolved modeling of gamma-ray flares, proposed structured jet scenarios, and investigations into the origin of high-energy emission through broadband spectral energy distribution (SED) modeling and multiwavelength variability analysis. I will also discuss the first ever low-frequency uGMRT observations of the full Palomar-Green (PG) quasar sample at 685 MHz. Collectively, these results emphasize the importance of broadband observations, from radio to gamma-rays, in probing AGN jet physics, variability, and unification.
