X-ray spectroscopy on Abell 478 with XMM-Newton
We report the results from a spatially resolved spectroscopy study with XMM-Newton on the relaxed cluster of galaxies Abell 478. From the EPIC data we extract a temperature profile and radial abundance profiles for Ne, Mg, Si, S, Ca, Fe and Ni. The abundance profiles follow the same trends as observed in other clusters. The spectra of the core of the cluster can be best fitted with a multi-temp...
متن کاملXMM-Newton and Chandra view of the Cluster Abell 85 and its X-Ray Filament
Abstract. From ROSAT data, the bright X-ray cluster Abell 85 was found to show a roughly symmetrical shape, on to which are superimposed several features, among which: (1) a blob or group of galaxies falling on to the main cluster, with the gas in the impact region probably hotter and the galaxies in that zone showing enhanced star formation; (2) a filament, either diffuse or made of small grou...
متن کاملAn XMM - Newton Observation of Abell 2597
We report on a 120ks XMM-Newton observation of the galaxy cluster Abell 2597. Results from both the European Photon Imaging Camera (EPIC) and the Reflection Grating Spectrometer (RGS) are presented. From EPIC we obtain radial profiles of temperature, density and abundance, and use these to derive cooling time and entropy. We illustrate corrections to these profiles for projection and point spre...
متن کاملA Search for X-Ray Flashes with XMM -Newton
We searched for X-ray flashes (XRFs) – which we defined as ∼10 s duration transient X-ray events observable in the 0.4-15 keV passband – in fields observed using XMM -Newton with the EPIC/pn detector. While we find two non-Poissonian events, the astrophysical nature of the events is not confirmed in fully simultaneous observations with the EPIC/MOS detectors, and we conclude that the events are...
