Identification of Two Radio Loud Narrow Line Seyfert 1 Galaxies at Gamma-Ray Energies

We report the discovery of gamma-ray emission from two radio-loud narrow-line Seyfert 1 galaxies using data from Fermi/LAT: J0804+3853 (z = 0.211) and J1443+4725 (z = 0.502). The objects were discovered due to singular, separate, and brief brightening events of a few months' duration during the first 66 months of Fermi observations. Also presented are our efforts thus far to monitor the optical photopolarimetric variability of these targets. This work brings the total number of this class identified at gamma-ray energies from seven to nine, thus representing a significant increase in this population of AGN. These findings can have strong implications with regard to our understanding of systems with relativistic jets.
