A Joint Mid-Infrared Spectroscopic and X-Ray Imaging Investigation of Liner Galaxies

S. Satyapal, R. M. Sambruna, R. P. Dudik

We present a comprehensive comparative high resolution mid-IR spectroscopic and X-ray imaging investigation of LINERs using archival observations from the ISO-SWS and the Chandra A…

On the origin of the X-rays and the nature of accretion in NGC 4261

M. Gliozzi, R. M. Sambruna, W. N. Brandt

We report on the X-ray properties of the radio galaxy NGC 4261, combining information from the XMM, Chandra, and SAX satellites. Goals of this study are to investigate the origin o…

Emission-Line Diagnostics of the Central Engines of Weak-Line Radio Galaxies

Karen T. Lewis, Michael Eracleous, Rita M. Sambruna

A handful of well-studied Weak-Line Radio Galaxies (WLRGs) have been traditionally classified as Low Ionization Nuclear Emission-line Regions (LINERs), suggesting that these two gr…

Chandra Observations of Nuclear X-ray Emission from a Sample of Radio Sources

J. K. Gambill, R. M. Sambruna, G. Chartas +5

We present the X-ray properties of a sample of 17 radio sources observed with the Chandra X-ray Observatory as part of a project aimed at studying the X-ray emission from their rad…

The XMM-Newton View of the Nucleus of NGC 4261

R. M. Sambruna, M. Gliozzi, M. Eracleous +2

We present the first results from an XMM-Newton observation of the FRI galaxy NGC 4261, which harbors a supermassive black hole and a low-ionization nuclear emission-line region (L…
