Suzaku Observations of Local Ultraluminous Infrared Galaxies

Stacy H. Teng, Sylvain Veilleux, Naohisa Anabuki +7

We report the results from our analysis of {\it Suzaku} XIS (0.5-10 keV) and HXD/PIN (15-40 keV) observations of five well-known local ULIRGs: {\em IRAS} F05189-2524, {\em IRAS} F0…

Radiatively Inefficient Accretion Flow in the Nucleus of NGC 1097

Rodrigo S. Nemmen, Thaisa Storchi-Bergmann, Feng Yuan +3

We present a model for the accretion flow around the supermassive black hole in the LINER nucleus of NGC 1097 which fits the optical to X-ray spectral energy distribution (SED). Th…

Extragalactic H_2O masers and X-ray absorbing column densities

J. S. Zhang, C. Henkel, M. Kadler +4

Having conducted a search for the 22 GHz water vapor line towards galaxies with nuclear activity, large nuclear column densities or high infrared luminosities, we present H_2O spec…

Radio Sources in Low-Luminosity Active Galactic Nuclei.IV. Radio Luminosity Function, Importance of Jet Power, and Radio Properties of the Complete Palomar Sample

Neil M. Nagar, Heino Falcke, Andrew S. Wilson

We present the completed results of a high resolution radio imaging survey of all (~200) low-luminosity active galactic nuclei (LLAGNs) and AGNs in the Palomar Spectroscopic Sample…

The X-ray Emissions from the M87 Jet: Diagnostics and Physical Interpretation

Eric S. Perlman, Andrew S. Wilson

We reanalyze the deep Chandra observations of the M87 jet, first examined by Wilson & Yang (2002). By employing an analysis chain that includes image deconvolution, knots HST-1 and…

The Murmur of the Sleeping Black Hole: Detection of Nuclear Ultraviolet Variability in LINER Galaxies

Dan Maoz, Neil M. Nagar, Heino Falcke +1

LINER nuclei, which are present in many nearby galactic bulges, may be the manifestation of low-rate or low-radiative-efficiency accretion onto supermassive central black holes. Ho…
