Angular Resolution of a Photoelectric Polarimeter in the Focus of an Optical System

Francesco Lazzarotto, Sergio Fabiani, Enrico Costa +12

The INFN and INAF Italian research institutes developed a space-borne X-Ray polarimetry experiment based on a X-Ray telescope, focussing the radiation on a Gas Pixel Detector (GPD)…

Radio-Loud Narrow-Line Seyfert 1 as a New Class of Gamma-Ray AGN

LAT Collaboration, G. Ghisellini, L. Maraschi +1

We report the discovery with Fermi/LAT of gamma-ray emission from three radio-loud narrow-line Seyfert 1 galaxies: PKS 1502+036 (z=0.409), 1H 0323+342 (z=0.061) and PKS 2004-447 (z…

Multiwavelength monitoring of the enigmatic Narrow-Line Seyfert 1 PMN J0948+0022 in March-July 2009

LAT Collaboration, E. Angelakis, C. Bailyn +39

Following the recent discovery of gamma rays from the radio-loud narrow-line Seyfert 1 galaxy PMN J0948+0022 (z=0.5846), we started a multiwavelength campaign from radio to gamma r…
