The outer regions of galaxy clusters: Chandra constraints on the X-ray surface brightness
S. Ettori, I. Balestra
(Abridged version) We study the properties of the X-ray surface brightness profiles in a sample of galaxy clusters that were observed with Chandra and have emission detectable with…
Evolution in the iron abundance of the ICM
I. Balestra, P. Tozzi, S. Ettori +4
We present a Chandra analysis of the X-ray spectra of 56 clusters of galaxies at , which cover a temperature range of keV. Our analysis is aimed at measuring th…
XMM-Newton observation of Mrk 110
Th. Boller, I. Balestra, W. Kollatschny
We report on the first XMM-Newton observation of the bright Narrow-Line Seyfert 1 galaxy Mrk 110. We find a narrow Fe K fluorescent line, a broad component FWHM ~ 16500 km/s of the…
Tracing the evolution in the iron content of the ICM
I. Balestra, P. Tozzi, S. Ettori +4
We present a Chandra analysis of the X-ray spectra of 56 clusters of galaxies at z>0.3, which cover a temperature range of 3>kT>15 keV. Our analysis is aimed at measuring the iron…
Tracing the evolution in the iron content of the ICM
I. Balestra, P. Tozzi, S. Ettori +5
We present a Chandra analysis of the X-ray spectra of 56 clusters of galaxies at z>0.3, which cover a temperature range 3<kT<15 keV. Our analysis is aimed at measuring the iron abu…
XMM-Newton spectral properties of the Ultraluminous IRAS Galaxy Mrk 273
I. Balestra, Th. Boller, L. Gallo +2
We present a 23 ks XMM-Newton observation of the ULIRG Mrk 273. The hard X-ray spectrum can be modeled by a highly absorbed power law plus an Fe Kalpha emission line. The iron line…
X-ray reprocessing in Seyfert Galaxies: simultaneous XMM-Newton/BeppoSAX observations
S. Bianchi, G. Matt, I. Balestra +2
We selected a sample of eight bright unobscured (at least at the iron line energy) Seyfert Galaxies observed simultaneously by XMM-Newton and BeppoSAX, taking advantage of the comp…
The reprocessing features in the X-ray spectrum of the NELG MCG-5-23-16
I. Balestra, S. Bianchi, G. Matt
We present results from the spectral analysis of the Seyfert 1.9 galaxy MCG-5-23-16, based on ASCA, BeppoSAX, Chandra and XMM-Newton observations. The spectrum of this object shows…
The origin of the iron lines in NGC 7213
S. Bianchi, G. Matt, I. Balestra +1
The analysis of a simultaneous XMM-Newton/BeppoSAX plus three previous BeppoSAX observations revealed that NGC 7213 is a rather peculiar Seyfert 1. No significant Compton reflectio…
The recent X-ray history of NGC 5506
S. Bianchi, I. Balestra, G. Matt +2
We present a detailed discussion of the spectral and spatial components of NGC 5506, based on XMM-Newton, Chandra and BeppoSAX observations. The overall picture consists of a nucle…
