X-ray properties of LINERs and low-luminosity Seyfert galaxies observed with ASCA. I. Observations and results.
TERASHIMA Y., IYOMOTO N., HO L.C. and PTAK A.F.
Abstract (from CDS):
Variability on timescales less than a day is uncommon in our sample. By comparing multiple observations made with ASCA or with published 2-10 keV observations from other satellites, we show that at least eight objects are variable on timescales of a week to several years. We find that the morphologies of many objects, both in the soft and hard bands, are consistent with being pointlike relative to the telescope point-spread function; a few are clearly extended in either or both energy bands.
The second paper of this series will discuss the physical interpretation of the X-ray emission and its implications for low-luminosity active galactic nuclei.
