Nonuniform cosmological birefringence and active galactic nuclei
Marc Kamionkowski California Institute of Technology, Mail Code 350-17, Pasadena, California 91125, USA (Received 21 April 2010; revised manuscript received 28 April 2010; published 25 August 2010) The CMB constrains the cosmological-birefringence rotation angle to be j j & 1 (1 ) out to redshifts z ’ 1100 for a rotation that is uniform across the sky. However, the rotation angle ð ; Þ may vary...
متن کاملAre There Rotation Measure Gradients across Active Galactic Nuclei Jets?
We report on multi-frequency polarimetry very long baseline interferometry observations of active galactic nuclei using the Very Long Baseline Array. These observations are used to construct images of the Faraday rotation measure (RM) in J1613+342, Mrk 501, 3C 371, and BL Lac. Despite having resolved the jets in total intensity and polarization for three of these sources no RM gradients are fou...
متن کاملObscured Active Galactic Nuclei
The properties of the absorption in type 2, narrow line AGNs are reviewed by focusing on the X-ray indicators. I discuss the properties of the cold absorbing medium (the putative torus) and of the reprocessed components, as well as their implications for the unified model. The relation between optical classification and X-ray absorption is examined. The case of “fossil” AGNs, whose type 2 class...
متن کاملNaked active galactic nuclei
In this paper we report the discovery of a new class of active galactic nucleus in which although the nucleus is viewed directly, no broad emission lines are present. The results are based on a survey for AGN in which a sample of about 800 quasars and emission line galaxies were monitored yearly for 25 years. Among the emission line galaxies was the expected population of Seyfert 2 galaxies wit...
متن کاملFuelling Active Galactic Nuclei
We suggest that most nearby active galactic nuclei are fed by a series of small– scale, randomly–oriented accretion events. Outside a certain radius these events promote rapid star formation, while within it they fuel the supermassive black hole. We show that the events have a characteristic time evolution. This picture agrees with several observational facts. The expected luminosity function i...
