Unidentified line in x-ray spectra of the Andromeda galaxy and Perseus galaxy cluster.
We report a weak line at 3.52±0.02 keV in x-ray spectra of the Andromeda galaxy and the Perseus galaxy cluster observed by the metal-oxide-silicon (MOS) and p-n (PN) CCD cameras of the XMM-Newton telescope. This line is not known as an atomic line in the spectra of galaxies or clusters. It becomes stronger towards the centers of the objects; is stronger for Perseus than for M31; is absent in t...
متن کاملDosimetry intercomparison using a 35-keV X-ray synchrotron beam.
The purpose of this study was to compare dose measurements using ion chamber and radiochromic film dosimetry for a 35-keV synchrotron beam useful for Auger electron therapy. A 1.3-GeV electron beam, transported through a 3-pole superconducting wiggler magnet, produced a polychromatic photon beam from which a 35-keV beam (3.3 mm Al HVL) was selected using a monochromator. A 2.8 cm x 2.5 cm field...
متن کاملX - ray structures in galaxy cluster cores ⋆
Using a set of ROSAT HRI deep pointings, we investigate the presence of small-scale structures in the central regions of clusters of galaxies. Our sample comprises 23 objects up to z=0.32, 13 of them known to host a cooling flow. Structures are detected and characterized using a wavelet analysis, their statistical significance being assessed by a rigorous treatment of photon noise. For all clus...
متن کاملAn X-ray Selected Galaxy Cluster at Z = 1.26
We report the discovery of an X-ray luminous galaxy cluster at z = 1.26. RXJ0848.9+4452 was selected as an X-ray cluster candidate in the ROSAT Deep Cluster Survey, on the basis of its spatial extent. Deep optical and near-IR imaging have revealed a galaxy overdensity around the peak of the X-ray Based in part on observations obtained at the W.M. Keck Observatory Based in part on observations o...
متن کاملRxj0142.0+2131: I. the Galaxy Content of an X-ray-luminous Galaxy Cluster at Z = 0.28
We present a photometric and spectroscopic study of stellar populations in the X-ray-luminous cluster of galaxies RXJ0142.0+2131 at z = 0.280. This paper analyses the results of high signal-to-noise spectroscopy, as well as g-, r-, and i-band imaging, using the Gemini Multi-Object Spectrograph on Gemini North. Of 43 spectroscopic targets, we find 30 cluster members over a range in color. Centra...
