“…These substructures are confirmed by recent XMM observations (Zhang et al, 2004). In addition, the optical and X-ray center of RBS653 differ by $40 00 (Schwope et al, 2000), which is a further indication for such a merging process.…”

“…All clusters were chosen from the ROSAT Bright Survey (henceforth RBS, Schwope et al, 2000) with the following criteria: (a) classified as clusters; (b) member of the Abell catalogue; (c) bolometric X-ray luminosity L X P 0.5 · 10 45 erg/s in the 0.5-2 keV band; (d) redshift range 0.1 6 z 6 0.52 and finally; (e) observability from La Silla/Paranal (d 6 20°). The resulting 22 galaxy clusters were observed under good seeing conditions (61 00 ) in the R and V band either with the Wide Field Imager (WFI@ESO2.2m) or with the SUperb Seeing Imager 2 (SUSI2@ESONTT).…”

“…Our project is based on a unique, well-defined sample of galaxy clusters which is necessary for the later purposes. The 22 clusters are the most X-ray luminous systems in the ROSAT Bright Survey (RBS) (Schwope et al, 2000). According to the L X À M cluster scaling relations (Reiprich and Bö hringer, 1999;Schindler, 1999) all systems in our sample are assumed to be very massive.…”

We present a first analysis of a deep X-ray spectrum of the isolated neutron star RBS1223 obtained with XMM-Newton. Spectral data from four new monitoring observations in 2005/2006 were combined with archival observations obtained in 2003 and 2004 to form a spin-phase averaged spectrum containing 290000 EPICpn photons. This spectrum shows higher complexity than its predecessors, and can be parameterised with two Gaussian absorption lines superimposed on a blackbody. The line centers, E 2 ≃ 2E 1 , could be regarded as supporting the cyclotron interpretation of the absorption features in a field B ∼ 4 × 10 13 G. The flux ratio of those lines does not support this interpretation. Hence, either feature might be of truly atomic origin.

Investigating possible unification of Seyfert galaxies and blazars in Fermi‐Large Area Telescope sample

Statistical analyses are invaluable methods used to understand intrinsic emission processes and the unification of extragalactic radio sources. In this paper, we collected radio, X-ray, and γ-ray data of blazars from the Fermi Large Area Telescope (Fermi-LAT) and Seyfert galaxies from the INTEGRAL/IBIS survey and investigated the relationship between the emission properties of Seyfert galaxies and blazar subclasses of flat-spectrum radio quasars (FSRQs) and BL Lac objects (BL Lacs). The results show from the average values that these objects follow a sequence that is indicative of probable Seyfert galaxies-BL Lacs-FSRQs unification. We discovered that Seyfert galaxies, BL Lacs, and FSRQs share similar emission characteristics in X-ray luminosity (L X-ray ), suggestive of fundamental connection while the γ-ray (L γ-ray ) and radio (L radio ) luminosities of Seyfert galaxies are the least powerful, signifying an evolving structure. From the two-dimensional Kolmogorov-Smirnov (K − S) test, we found that Seyfert galaxies differ from the blazar subclasses in L radio while there is no significant difference between them in L X-ray and L γ-ray which implies that high-energy emissions in Seyfert galaxies and blazar subclasses may come from the same emission mechanism. Significant positive correlations (with coefficient r > 0.60) exist between the high-energy luminosities (X-ray and γ-ray) and the low-energy components (radio) within the whole sample of blazars and Seyfert galaxies implying a form of connection between them. These results are not only consistent with the prediction of the unified scheme for blazars but also show that Seyfert galaxies have an evolutionary link with blazar subclasses.
