Absorption Of X-rays In The Interstellar Medium
We present an improved model for the absorption of X-rays in the interstellar medium (ISM) intended for use with data from future X-ray missions with larger effective areas and increased energy
Rossi X‐Ray Timing Explorer Observation of Cygnus X‐1. II. Timing Analysis
We present timing analysis for a Rossi X-Ray Timing Explorer (RXTE) observation of Cygnus X-1 in its hard/low state. This was the first RXTE observation of Cyg X-1 taken after it transited back to
A study of magnetic fields of accreting X-ray pulsars with the Rossi X-ray Timing Explorer
Using a consistent set of models, we parameterized the X-ray spectra of all accreting pulsars in the Rossi X-Ray Timing Explorer (RXTE) database that exhibit cyclotron resonance scattering features
eROSITA science book: mapping the structure of the energetic universe
eROSITA is the primary instrument on the Russian SRG mission. In the first four years of scientific operation after its launch, foreseen for 2014, it will perform a deep survey of the entire X-ray
Letter of intent for KM3NeT 2.0
The main objectives of the KM3NeT Collaboration are (i) the discovery and subsequent observation of high-energy neutrino sources in the Universe and (ii) the determination of the mass hierarchy of
Spectral formation in accreting X-ray pulsars: bimodal variation of the cyclotron energy with luminosity
Context. Accretion-powered X-ray pulsars exhibit significant variability of the cyclotron resonance scattering feature (CRSF) centroid energy on pulse-to-pulse timescales, and also on much longer
Irradiation of an accretion disc by a jet: general properties and implications for spin measurements of black holes
X-ray irradiation of the accretion disc leads to strong reflection features, which are then broadened and distorted by relativistic effects. We present a detailed, general relativistic approach to
The role of the reflection fraction in constraining black hole spin
In many active galaxies, the X-ray reflection features from the innermost regions of the accretion disc are relativistically distorted. This distortion allows us to measure parameters of the black
Polarized Gamma-Ray Emission from the Galactic Black Hole Cygnus X-1
This gamma-ray emission originates from a jet of relativistic particles that is formed in close proximity to the black hole, and is measured with the International Gamma-Ray Astrophysics Laboratory Imager on Board the Integral Satellite (INTEGRAL/IBIS) telescope.
Broad emission lines for a negatively spinning black hole
We present an extended scheme for the calculation of the profiles of emission lines from accretion discs around rotating black holes. The scheme includes discs with angular momenta which are parallel
