Probing the physical properties of the intergalactic medium using blazars
Tony Dalton, Simon L. Morris, Michele Fumagalli +1
We use Swift blazar spectra to estimate the key intergalactic medium (IGM) properties of hydrogen column density(Nhxigm), metallicity and temperature over a redshift range of 0.03…
Nitrogen X-ray absorption in the local ISM
Efrain Gatuzz, Javier A. García, Timothy R. Kallman
Nitrogen is one of the most abundant metals in the interstellar medium (ISM), and thus it constitutes an excellent test to study a variety of astrophysical environments, ranging fr…
Silicon X-ray absorption in the Galactic ISM: the gaseous component
E. Gatuzz, T. W. Gorczyca, M. F. Hasoglu +3
We present a detailed analysis of the gaseous component of the Si K edge using high-resolution Chandra spectra of low-mass X-ray binaries. We fit the spectra with amodified version…
Simultaneous detection of an intrinsic absorber and a compact jet emission in the X-ray binary IGR J17091-3624 during a hard accretion state
E. Gatuzz, M. Díaz Trigo, J. C. A. Miller-Jones +1
We present a detailed analysis of three XMM-Newton observations of the black hole low-mass X-ray binary IGR~J17091-3624 taken during its 2016 outburst. Radio observations obtained…
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…
