Simultaneous XMM-Newton and HST-COS observation of 1H0419-577: the absorbing and emitting ionized gas
L. Di Gesu, E. Costantini, N. Arav +7
In this paper we analyze the X-ray, UV and optical data of the Seyfert 1.5 galaxy 1H0419-577, with the aim of detecting and studying an ionized-gas outflow. The source was observed…
A phenomenological model for the X-ray spectrum of Nova V2491 Cygni
Ciro Pinto, Jan-Uwe Ness, Frank Verbunt +3
The X-ray flux of Nova V2491 Cyg reached a maximum some forty days after optical maximum. The X-ray spectrum at that time, obtained with the RGS of XMM-Newton, shows deep, blue-shi…
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…
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…
Characterizing the UV and X-ray Outflow in Mrk 509
G. A. Kriss, N. Arav, J. S. Kaastra +15
We observed Mrk 509 during the fall of 2009 during a multiwavelength campaign using XMM-Newton, Chandra, HST/COS, SWIFT, and Integral. The 600-ks XMM/RGS spectrum finds two kinemat…
