Simultaneous mm/X-ray intraday variability in the radio-quiet AGN MCG+08-11-11
P. O. Petrucci, V. Piétu, E. Behar +10
Most of the Active Galactic Nuclei (AGN) are radio-quiet (RQ) and, differently from radio-loud (RL) AGN, do not show signature of large-scale and powerful jets. The physical origin…
Stellar flares observed by LOFT: implications for the physics of coronae and for the "space weather" environment of extrasolar planets
S. A. Drake, E. Behar, J. G. Doyle +7
This is a White Paper in support of the mission concept of the Large Observatory for X-ray Timing (LOFT), proposed as a medium-sized ESA mission. We discuss the potential of LOFT f…
Multiwavelength campaign on Mrk 509 XIV. Chandra HETGS spectra
J. S. Kaastra, J. Ebrero, N. Arav +14
We present in this paper the results of a 270 ks Chandra HETGS observation in the context of a large multiwavelength campaign on the Seyfert galaxy Mrk 509. The HETGS spectrum allo…
A fast and long-lived outflow from the supermassive black hole in NGC 5548
J. S. Kaastra, G. A. Kriss, M. Cappi +31
Supermassive black holes in the nuclei of active galaxies expel large amounts of matter through powerful winds of ionized gas. The archetypal active galaxy NGC 5548 has been studie…
