We investigate the relation between X-ray nuclear emission, optical emission line luminosities and black hole masses for a sample of 47 Seyfert galaxies. The sample, which has been selected from the Palomar optical spectroscopic survey of nearby galaxies (Ho et al. 1997a, ApJS, 112, 315), covers a wide range of nuclear powers, from L2" 10keV # 10 43 erg/s down to very low luminosities (L2" 10keV # 10 38 erg/s). Best available data from Chandra, XMM-Newton and, in a few cases, ASCA observations…

ARE X-RAY EMITTING CORONAE AROUND SUPERMASSIVE BLACK HOLES OUTFLOWING?
Hard X-ray emission in radio-quiet active galactic nuclei (AGNs) is believed to be produced via inverse Compton scattering by hot and compact coronae near the supermassive black hole. However, the
Accretion Properties of a Sample of Hard X-Ray (<60 keV) Selected Seyfert 1 Galaxies
We examine the accretion properties in a sample of 42 hard (3-60 keV) X-ray selected nearby broad-line active galactic nuclei (AGNs). The energy range in the sample is harder than that usually used
X-RAY PROPERTIES OF INTERMEDIATE-MASS BLACK HOLES IN ACTIVE GALAXIES. III. SPECTRAL ENERGY DISTRIBUTION AND POSSIBLE EVIDENCE FOR INTRINSICALLY X-RAY-WEAK ACTIVE GALACTIC NUCLEI
We present a systematic X-ray study, the third in a series, of 49 active galactic nuclei with intermediate-mass black holes (IMBH; ~105-106 M ☉) using Chandra observations. We detect 42 out of 49
Simultaneous X-ray and optical observations of true type 2 Seyfert galaxies
We present the results of a campaign of simultaneous X-ray and optical observations of ‘true’ type 2 Seyfert galaxies candidates, i.e. active galactic nuclei without a broad-line region (BLR). Out of
A new sample of X-ray selected narrow emission-line galaxies - I. The nature of optically elusive AGN
Using the 3XMM catalogue of serendipitous X-ray sources, and the SDSS-DR9 spectroscopic catalogue, we have obtained a new sample of X-ray selected narrow emission line galaxies. The standard optical
XMM-NEWTON OBSERVATIONS OF THE SEYFERT 2 GALAXY NGC 7590: THE NATURE OF X-RAY ABSORPTION
We present the analysis of three XMM-Newton observations of the Seyfert 2 galaxy NGC 7590. The source was found to have no X-ray absorption in the low spatial resolution ASCA data. The XMM-Newton
The effects of X-ray absorption variability in NGC 4395
We present a new X-ray analysis of the dwarf Seyfert galaxy NGC 4395, based on two archival XMM–Newton and Suzaku observations. This source is well known for a series of remarkable properties: one of
An X-ray view of 82 LINERs with Chandra and XMM-Newton data
We present the results of a homogeneous X-ray analysis for 82 nearby low-ionisation, narrow emission-line regions (LINERs) selected from the catalogue of Carrillo et al. (1999, Rev. Mex. Astron.
ON THE X-RAY PROPERTIES OF H2O MASER HOST GALAXIES
All galaxies beyond the Magellanic clouds with detected H2O maser emission so far are investigated and their X-ray observations are collected in detail to probe the X-ray properties of this special
