Determination of a magnetization parameter of the parsec-scale AGN jets
Determination magnetization parameter parsec-scale AGN jets
2011/9/27
The observed shift of the core of the relativistic AGN jets as a function of frequency allows us to evaluate the number density of outflowing plasma and, hence, the magnetization parameter. New analys...
Multiwavelength campaign on Mrk 509. III. The 600 ks RGS spectrum: unravelling the inner region of an AGN
Active Galactic Nuclei – X-ray spectroscopy – XMM-Newton – outfl ows – individual: Mrk 509 – galaxies: Seyfert
2011/9/27
We present the results of our 600 ks RGS observation as part of the multiwavelength campaign on Mrk 509. The very high quality of the spectrum allows us to investigate the ionized outflow with an unpr...
Anisotropic AGN Outflows and Enrichment of the Intergalactic Medium. II. Metallicity
cosmology — galaxies active — galaxies jets — intergalactic medium — methods
2010/11/15
We investigate the large-scale influence of outflows from AGNs in enriching the IGM with metals in a cosmological context. We combine cosmological simulations of large-scale structure formation with a...
Fe-K line probing of material around the AGN central engine with Suzaku
galaxies active — galaxies Seyfert — X-rays galaxies
2010/11/11
We systematically analyzed the high-quality Suzaku data of 88 Seyfert galax-ies, about 31% of which are Compton-thick AGNs. We obtained a clear relation between the absorption column density and the e...
The Origin of [OII] Emission in Recently Quenched AGN Hosts
galaxies active — galaxies clusters general — galaxies evolution X-rays galaxies
2010/11/11
We have employed emission-line diagnostics derived from DEIMOS and NIRSPEC spectroscopy to
determine the origin of the [OII] emission line observed in six AGN hosts at z 0.9. These galaxies are a s...
The Ultraviolet-X-ray connection in AGN outflows
X-ray Spectroscopy UV spectroscopy Active Galactic Nuclei absorption lines
2010/11/15
In this paper I review the recent progress in understanding the physics of the gas outflowing from active galactic nuclei and its impact on the surrounding environment, using the combined information ...
Comparison of AGN and Nuclear Starburst Activity in Seyfert 1 and 2 Galaxies over a Wide Luminosity Range Based on Near-infrared 2-4 micrometer Spectroscopy
Galaxy Astrophysics (astro-ph.GA)
2011/1/4
We present near-infrared K- (1.9-2.5 micrometer) and L- (2.8-4.2 micrometer) band spectroscopy of 22 Seyfert nuclei. We use two methods to investigate the presence of nuclear starbursts.
The LABOCA survey of the Extended Chandra Deep Field South: Two modes of star formation in AGN hosts?
galaxies active galaxies starburst infrared galaxies
2010/3/8
We study the co-existence of star formation and AGN activity in X-ray selected AGN by analyzing stacked 870um submm emission from a deep and wide map of the Extended Chandra Deep Field South, obtained...
