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 کاملA Chandra X-ray Study of NGC 1068: II. The Luminous X-ray Source Population
We present an analysis of the compact X-ray source population in the Seyfert 2 galaxy NGC 1068, imaged with a ∼ 50 ks Chandra observation. We find a total of 84 compact sources on the S3 chip, of which 66 are located within the 25.0 B-magnitude (arc sec)−2 isophote of the galactic disk of NGC 1068. Spectra have been obtained for the 21 sources with at least 50 counts, and modeled with both mult...
متن کاملAn X-ray View of Radio Sources
We review recent examples where the synergy between radio and X-ray observations has led to substantial progress in understanding astronomical systems. The sub-arcsecond imaging capabilities of the Chandra X-ray observatory provides a 100-fold improvement for comparing X-ray and radio structures. We specifically discuss examples which provide insight into the outflow of material and energy from...
متن کاملMultiwavelength Observations of Markarian 421 in March 2001: an Unprecedented View on the X-ray/tev Correlated Variability
We present a detailed analysis of week-long simultaneous observations of the blazar Mrk 421 at 2–60 keV X-rays (RossiXTE) and TeV γ-rays (Whipple and HEGRA) in 2001. Accompanying optical monitoring was performed with the Mt. Hopkins 48" telescope. The unprecedented quality of this dataset enables us to establish the existence of the correlation between the TeV and X-ray luminosities, and also t...
متن کاملThe ultraluminous X - ray source population of NGC 4485 / 4490 .
We report the results of spectral and temporal variability studies of the ultraluminous Xray sources (ULXs) contained within the interacting pair of galaxies NGC 4485/4490, combining Chandra and XMM-Newton observations. Each of the four separate observations provide at least modest quality spectra and light curves for each of the six previously identified ULXs in this system; we also note the p...
