Carbon X-ray absorption in the local ISM: fingerprints in X-ray Novae spectra
E. Gatuzz, J. -U. Ness, T. W. Gorczyca +3
We present a study of the C K-edge using high-resolution LETGS Chandra spectra of four novae during their super-soft-source (SSS) phase. We identified absorption lines due to C~ii…

X-ray outflows of active galactic nuclei warm absorbers: A 900 ks Chandra simulated spectrum
J. M. Ramirez-Velasquez, J. Garcia
We report on the performance of the statistical, X-ray absorption lines identification procedure XLINE-ID. As illustration, it is used to estimate the time averaged gas density $n_…

The dust scattering component of X-ray extinction: Effects on continuum fitting and high-resolution absorption edge structure
L. Corrales, J. Garcia, J. Wilms +1
Small angle scattering by dust grains causes a significant contribution to the total interstellar extinction for any X-ray instrument with sub-arcminute resolution (Chandra, Swift,…
