Variability of a stellar corona on a time scale of days
Raanan Nordon, Ehud Behar, Stephen A. Drake
Elemental abundance effects in active coronae have eluded our understanding for almost three decades, since the discovery of the First Ionization Potential (FIP) effect on the sun.…
Accretion and outflow of gas in Markarian 509
Jelle Kaastra, Pierre-Olivier Petrucci, Massimo Cappi +13
A major uncertainty in models for photoionised outflows in AGN is the distance of the gas to the central black hole. We present the results of a massive multiwavelength monitoring…
Toward a Unified AGN Structure
Demosthenes Kazanas, Keigo Fukumura, Ehud Behar +2
We present a unified model for the structure and appearance of accretion powered sources across their entire luminosity range from galactic X-ray binaries to luminous quasars, with…
Broad Band Photometric Reverberation Mapping of NGC 4395
Haim Edri, Stephen E. Rafter, Doron Chelouche +2
We present results of broad band photometric reverberation mapping (RM) to measure the radius of the broad line region, and subsequently the black hole mass (M), in the…
