In January/April 2015 Fermi-LAT detected strong gamma-ray flares from FSRQ PKS 1441+25 (z=0.939). During the flare in January the daily γ-ray flux reached up to (1.72±0.19)×10-6 photon cm-2 s-1 with the flux double time of ≈ 1.4 days. This flare is accompanied by similar flux increase, also in the X-ray band as observed by Swift XRT. The available X-ray and γ-ray data allows to constrain the underlying electron distribution parameters through Markov Chain Monte Carlo method. The emission in the low state can be interpreted by synchrotron self-Compton emission from the electron population producing the radio-to-X-ray emission in the jet while in the high state the emission is mostly produced from inverse-Compton up scattering of the external photons from dusty torus.

The gamma-ray detection by Fermi-LAT from non blazar active galactic nuclei shows that these are different and potentially very interesting classes of gamma-ray emitters. This provides an alternative approach for studying high energy emission processes compared to blazars where the emission is strongly Doppler boosted. Up to now there are 32 non-blazar AGNs detected in the gamma-ray band which are included in the third catalog of AGNs detected by Fermi LAT. We will present a detailed investigation of the gamma-ray emission from non-blazar AGNs based on seven years of Fermi LAT data. The accumulation of a larger data set allows detailed temporal analysis in short and long time scales as well as to study the spectrum with better statistics at energies above several GeV. Also the possible origin of the observed gamma-rays will be discussed considering both compact and extended regions. [ABSTRACT FROM AUTHOR]
