Prior to the Fermi-LAT era. only two classes of Active Galactic Nuclei (AGN) were thought to harbor relativistic jets that radiate up to gamma-ray energies: blazars and radio galaxies. The detection of variable gamma-ray emission from Narrow Line Seyfert 1 (NLSy1) galaxies has put them on the spotlight as a new class of gamma-ray emitting AGN. In this respect. https://www.jmannino.com/limited-offer-Disney-Mickey-Mouse-Pattern-Formation-Galaxy-A14-5G-Clear-Case-p103475-top-grab/
