Gamma-ray emitting narrow-line Seyfert 1 galaxies. New discoveries and open questions
F. D'Ammando, M. Orienti, J. Finke +2
The discovery of gamma-ray emission from 5 radio-loud narrow-line Seyfert 1 galaxies revealed the presence of a possible emerging third class of AGNs with relativistic jets, in add…
Multi-Wavelength Observations of PKS 2142-75 during Active and Quiescent Gamma-Ray States
Michael Dutka, Roopesh Ojha, Katja Pottschmidt +13
PKS2142-75 (a.k.a. 2FGL J2147.4-7534) is a flat-spectrum radio quasar that was observed quasi-simultaneously by a suite of instruments across the elec- tromagnetic spectrum during…
The Cosmic Evolution of Fermi BL Lacertae Objects
M. Ajello, R. W. Romani, D. Gasparrini +14
Fermi has provided the largest sample of gamma-ray selected blazars to date. In this work we use a uniformly selected set of 211 BL Lacertae (BL Lac) objects detected by it Fermi d…
Relativistic jets in narrow-line Seyfert 1 galaxies. New discoveries and open questions
F. D'Ammando, M. Orienti, J. Finke +2
Before the launch of the Fermi satellite only two classes of AGNs were known to produce relativistic jets and thus emit up to the gamma-ray energy range: blazars and radio galaxies…
Multifrequency studies of the narrow-line Seyfert 1 galaxy SBS 0846+513
F. D'Ammando, M. Orienti, J. Finke +10
The narrow-line Seyfert 1 galaxy SBS 0846+513 was first detected by the Large Area Telescope (LAT) on-board Fermi in 2011 June-July when it underwent a period of flaring activity.…
On the Physics Connecting Cosmic Rays and Gamma Rays: Towards Determining the Interstellar Cosmic Ray Spectrum
C. D. Dermer, J. D. Finke, R. J. Murphy +10
Secondary nuclear production physics is receiving increased attention given the high-quality measurements of the gamma-ray emissivity of local interstellar gas between ~50 MeV and…
