We analyze a Chandra-HETGS observation of the single G-type giant HR 9024. The high flux allows us to examine spectral line and continuum diagnostics at high...
X-ray fluorescence modelling for Solar system regoliths: Effects of viewing geometry, particle size, and surface roughness
We study X-ray fluorescent emission and monochromatic scattering from the surfaces of asteroids and other atmosphereless solar-system objects using numerical...
X-Ray High Resolution Spectra in the VO: The case of XMM-Newton RGS Data
We present ``BiRD'', a tool for the browsing and visualisation of XMM-Newton high-resolution spectra. The dataset accessed by this utility consists of RGS...
Magnetized plasma is emerging continually from the solar interior into the atmosphere. Magnetic flux emergence events and their consequences in the solar...
X-Ray Jets in Coronal Holes: Numerical Simulation and Hinode Observations
We report on our recent 3D numerical models of the launching of hot, high-speed jets in a coronal hole following the emergence of magnetized plasma from the...
X-ray monitoring of optical novae in M31 (Pietsch+, 2007)
Optical novae have recently been identified as the major class of supersoft X-ray sources in M 31 based on ROSAT and early XMM-Newton and Chandra observations...
We have investigated the nature of the energy source of 36 LINERs with Chandra X-ray observations selected from the catalogue by Carrillo et al. (1999). In most...
X-ray nuclear emission of a sample of LINER Galaxies
We report the results from an homogeneous analysis of the X-ray (ACIS-S/Chandra) data available for a sample of 52 LINER galaxies. The X-ray morphology has been...
We present a detailed X-ray spectral analysis of the sources in the 1Ms catalog of the Chandra Deep Field South (CDFS, J/ApJS/139/369) taking advantage of...
