Simultaneous Millimeter-wave and X-ray monitoring of the Seyfert Galaxy NGC 7469
Ehud Behar, Shai Kaspi, Gabriel Paubert +6
We report on daily monitoring of the Seyfert galaxy NGC 7469, around 95 GHz and 143 GHz, with the IRAM 30 m radio telescope, and with the Swift X-Ray and UV/Optical telescopes, ove…
Multi-wavelength campaign on NGC 7469 V. Analysis of the HST/COS observations: Super solar metallicity, distance, and trough variation models
N. Arav, X. Xu, G. A. Kriss +18
Aims. Our aim is to determine the distance of the UV outflow components from the central source, their abundances and total column density, and the mechanism responsible for their…
Cosmological evolution of the absorption of -ray burst X-ray afterglows
Roi Rahin, Ehud Behar
X-ray absorption of -ray burst (GRB) afterglows is prevalent yet poorly understood. X-ray derived neutral hydrogen column densities () of GRB X-ray afterglows show an…
X-Ray Spectrum of RBS 315: Absorption or Intrinsic Curvature
Sivan Ben Haim, Ehud Behar, Richard F. Mushotzky
X-ray absorption of high-redshift quasars is enigmatic, because it remains unclear where in the universe the absorbing gas is. If absorption occurs near the high-z host, it could h…
Multi-wavelength Campaign on NGC 7469 VI. Photoionisation Modelling of the Emission Line Regions and the Warm Absorber
S. Grafton-Waters, G. Branduardi-Raymont, M. Mehdipour +16
Aims. We aim to investigate and characterise the photoionised X-ray emission line regions within NGC 7469. Methods. We apply the photoionisation model, PION, within the spectral fi…
The physics and astrophysics of X-ray outflows from Active Galactic Nuclei
Sibasish Laha, Randall Smith, Panayiotis Tzanavaris +20
The highly energetic outflows from Active Galactic Nuclei detected in X-rays are one of the most powerful mechanisms by which the central supermassive black hole (SMBH) interacts w…
