An X–ray View of WLRGs/LINERs
We present X–ray observations of nine Weak-Line Radio Galaxies (WLRGs), optically classified as confirmed or possible Low Ionization Nuclear Emission– line Regions (LINERs). The data were taken from the Chandra, XMM–Newton, and BeppoSAX archives. The Chandra images typically show complex X-ray morphologies, with hard (2–10 keV) point sources embedded in diffuse soft (0.3– 2.0 keV) emission in a...
متن کاملVariability in LINERs
A small number of LINERs have been seen to display variable Hα emission with a very broad, double-peaked profile. Recent observations with the Hubble Space Telescope indicate that such emission may be a common attribute of LINERs. The double-peaked or doubleshouldered line profiles resemble those found in a subset of broad-line radio galaxies. Several lines of argument suggest that such feature...
متن کاملHard X-ray Emission and the Ionizing Source in LINERs
We report X-ray fluxes in the 2–10 keV band from LINERs (low-ionization nuclear emission-line regions) and low-luminosity Seyfert galaxies obtained with the ASCA satellite. Observed X-ray luminosities are in the range between 4×10 and 5×10 ergs s, which are significantly smaller than that of the “classical” low-luminosity Seyfert 1 galaxy NGC 4051. We found that X-ray luminosities in 2–10 keV o...
متن کاملX-ray Variability in M87
We present the evidence for X-ray variability from the core and from knot A in the M87 jet based on data from two observations with the Einstein Observatory High Resolution Imager (HRI) and three observations with the ROSAT HRI. The core intensity showed a 16% increase in 17 months ('79-'80); a 12% increase in the 3 years '92 to '95; and a 17% drop in the last half of 1995. The intensity of kno...
