Jetted Active Galactic Nuclei in the Era of Fermi Gamma-ray Space Telescope

The launch of the Fermi gamma-ray space telescope about a decade ago has revolutionized the field of gamma-ray astronomy.  It has led to the identification of two new extragalactic  gamma-ray emitting population namely radio galaxies and narrow line Seyfert 1 ( gamma-NLSy1) galaxies.  In particular, the detection of NLSy1 sources in  gamma-rays has provided a strong evidence that jets are ubiquitously present in AGN.  
Coordinated observational programs with Fermi, both from ground (radio, optical and IR) and space (e.g. Swift and NuSTAR), have enabled the accumulation of a wealth of multi-wavelength data for many active galactic nuclei (AGN) that hosts relativistic jets.  These data sets have brought to focus several pitfalls in our current understanding of the physical processes happening in the central regions of beamed AGNs.  Also, our detailed broadband spectral energy distribution modeling of a few bright blazars has highlighted the tension between observations and theory.
I will present results of our ongoing efforts to characterize a few fundamental properties of jetted AGN population, e.g. accretion-jet connection, covering a wide range of accretion and black hole mass, particularly highlighting the role of -NLSy1 galaxies in the jet unification scheme.   I will also summarize (i) the challenges thrown open by new multi-wavelength observations, (ii) the efforts needed to understand data, and (iii) upcoming initiatives in the international scenario that can improve our understanding of the central engine of AGN.
