The Soft-Excess in Mrk 509: Warm Corona or Relativistic Reflection?
Javier A. Garcia, Erin Kara, Dominic Walton +15
We present the analysis of the first NuSTAR observations ( ks), simultaneous with the last SUZAKU observations ( ks), of the active galactic nucleus of the brigh…
On the discrepancy between the X-ray and UV absorption measurements of OVI in the local ISM
Efraín Gatuzz, Javier A. García, Timothy R. Kallman
The total amount of OVI present in the interstellar medium (ISM) obtained via absorption measurements in UV and X-ray spectra is currently in disagreement, with the latter being si…
Chandra high-resolution spectra of 4U~1630-47: the disappearance of the wind
E. Gatuzz, M. Diaz Trigo, J. C. A. Miller-Jones +1
We present the analysis of six {\it Chandra} X-ray high-resolution observations of the black hole low-mass X-ray binary 4U~1630-47 taken during its 2012-2013 outburst. {\rm Fe}~{\s…
3D mapping of the neutral X-ray absorption in the local interstellar medium: The Gaia and XMM-Newton synergy
Efraín Gatuzz, S. Rezaei Kh., Timothy R. Kallman +4
We present a three-dimensional map of the hydrogen density distribution in the Galactic interstellar medium. The hydrogen equivalent column densities were obtained from the Explori…
What we learn from the X-ray grating spectra of Nova SMC 2016
M. Orio, J. -U. Ness, A. Dobrotka +17
Nova SMC 2016 has been the most luminous nova known in the direction of the Magellanic Clouds. It turned into a very luminous supersoft X-ray source between day 16 and 28 after the…
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…
