High-resolution X-ray spectroscopy of the low and high states of the Seyfert 1 galaxy NGC 4051 with Chandra LETGS
K. C. Steenbrugge, M. Fenovcik, J. S. Kaastra +2
Methods. We analyse two observations taken with the Low Energy Transmission Grating Spectrometer of Chandra. We investigated the spectral response to a sudden flux decrease by a fa…
Multiwavelength study of Cygnus A II. X-ray inverse-Compton emission from a relic counterjet and implications for jet duty-cycles
K. C. Steenbrugge, K. M. Blundell, P. Duffy
The duty-cycle of powerful radio galaxies and quasars such as the prototype Cygnus A is poorly understood. X-ray observations of inverse-Compton scattered Cosmic Microwave Backgrou…
Multiwavelength study of Cygnus A I. Precession and slow jet speeds from radio observations
K. C. Steenbrugge, K. M. Blundell
We study the jet and counterjet of the powerful classical double FRII radio galaxy Cygnus A as seen in the 5, 8 and 15-GHz radio bands using the highest spatial resolution and sign…
Detection of a relic X-ray jet in Cygnus A
K. C. Steenbrugge, K. M. Blundell, P. Duffy
We present a 200 ks Chandra ACIS-I image of Cygnus A, and discuss a long linear feature seen in its counterlobe. This feature has a non-thermal spectrum and lies on the line connec…
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…
Ionization structure of the warm wind in NGC 5548
K. C. Steenbrugge, J. S. Kaastra, D. M. Crenshaw +7
We present the results from our 140 ks XMM-Newton and 500 ks Chandra observation of NGC 5548. The velocity structure of the X-ray absorber is consistent with the velocity structure…
