Chemical Abundances in AGN Environment: X-Ray/UV Campaign on the MRK 279 Outflow
Nahum Arav, Jack R. Gabel, Kirk T. Korista +11
We present the first reliable determination of chemical abundances in an AGN outflow. The abundances are extracted from the deep and simultaneous FUSE and HST/STIS observations of…
X-Ray/Ultraviolet Observing Campaign of the Markarian 279 Active Galactic Nucleus Outflow: a close look at the absorbing/emitting gas with Chandra-LETGS
E. Costantini, J. S. Kaastra, N. Arav +12
We present a Chandra-LETGS observation of the Seyfert 1 galaxy Mrk 279. This observation was carried out simultaneously with HST-STIS and FUSE, in the context of a multiwavelength…
High-resolution X-ray spectroscopy of the Narrow line Seyfert 1 galaxy NGC 4051 with Chandra LETGS
M. Fenovcik, J. S. Kaastra, E. Costantini +2
We study the absorption and emission properties of the photoionised gas near one of the brightest and most variable AGN, the Seyfert galaxy NGC 4051, in order to constrain the geom…
The X-ray Halo of GX5-1
Randall K Smith, T. M. Dame, Elisa Costantini +1
Using Chandra observations we have measured the energy-resolved dust-scattered X-ray halo around the low-mass X-ray binary GX5-1, which shows signs of both singly- and multiply-sca…
