Gamma-ray Emitting Narrow Line Seyfert 1 Galaxies: Past, Present, & Future

The detection of significant gamma-ray emission from about a-dozen radio-loud narrow line Seyfert 1 (NLSy1) galaxies by Fermi-Large Area Telescope has opened up a realm to explore the physical conditions needed to launch relativistic jets in a different central engine and host galaxy environment than that is known for more-common jetted active galactic nuclei, i.e. blazars. Promising results acquired from various multi-wavelength campaigns are converging to a scenario in which NLSy1 sources can be considered as 'nascent' blazars. In this talk, I will discuss the broadband properties of gamma-ray detected NLSy1 galaxies and results acquired by using these enigmatic objects as an effective tool to reveal the origin of relativistic jets.
