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…
The ASTRO-H X-ray Observatory
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +220
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will…
Multiwavelength Campaign on Mrk 509 X. Lower limit on the distance of the absorber from HST COS and STIS spectroscopy
N. Arav, D. Edmonds, B. Borguet +15
Active Galactic Nuclei often show evidence of photoionized outflows. A major uncertainty in models for these outflows is the distance () to the gas from the central black hole.…
Multiwavelength campaign on Mrk 509 IX. The Galactic foreground
C. Pinto, G. A. Kriss, J. S. Kaastra +5
The diffuse gas in and nearby the Milky Way plays an important role in the evolution of the entire Galaxy. It has a complex structure characterized by neutral, weakly and highly io…
The continued spectral and temporal evolution of RX J0720.4-3125
Markus M. Hohle, Frank Haberl, Jacco Vink +4
RX J0720.4-3125 is the most peculiar object among a group of seven isolated X-ray pulsars (the so-called "Magnificent Seven"), since it shows long-term variations of its spectral a…
Multiwavelength campaign on Mrk 509 VIII. Location of the X-ray absorber
J. S. Kaastra, R. G. Detmers, M. Mehdipour +14
The bright Seyfert 1 galaxy Mrk 509 was monitored by XMM-Newton and other satellites in 2009 to constrain the location of the outflow. We have studied the response of the photoioni…
