Peering into the central region of a nano-quasar: XMM-Newton and Chandra views of the CH Cyg Symbiotic System
J. A. Toalá, O. González-Martín, M. Karovska +3
We present the analysis of archival XMM-Newton and Chandra observations of CH Cyg, one of the most studied symbiotic stars (SySts). The combination of the high-resolution XMM-Newto…
X-ray spectral variability of LINERs selected from the Palomar sample
L. Hernández-García, O. González-Martín, J. Masegosa +1
Variability is a general property of active galactic nuclei (AGN). At X-rays, the way in which these changes occur is not yet clear. In the particular case of low ionisation nuclea…
X-ray spectral variability of seven LINER nuclei with XMM-Newton and Chandra data
L. Hernández-García, O. González-Martín, I. Márquez +1
One of the most important features in active galactic nuclei (AGN) is the variability of their emission. Variability has been discovered at X-ray, UV, and radio frequencies on time…
