Chandra temperature and metallicity maps of the Perseus cluster core
We present temperature and metallicity maps of the Perseus cluster core obtained with the Chandra X-ray Observatory. We find an overall temperature rise from ∼ 3.0 keV in the core to ∼ 5.5 keV at 120 kpc and a metallicity profile that rises slowly from ∼ 0.5 solar to ∼ 0.6 solar inside 60 kpc, but drops to ∼ 0.4 solar at 120 kpc. Spatially resolved spectroscopy in small cells shows that the tem...
متن کاملChandra Imaging of the X - ray Core of the Virgo Cluster
We report sub-arcsecond X-ray imaging spectroscopy of M87 and the core of the Virgo cluster with the Chandra X-ray Observatory. The X-ray morphology shows structure on arcsecond (∼ 100 pc) to ten arcminute (∼ 50 kpc) scales, the most prominent feature being an “arc” running from the east, across the central region of M87 and off to the southwest. A ridge in the radio map, ending in an “ear”-sha...
متن کاملChandra imaging of the X - ray core of Abell 1795
We report the discovery of a 40 arcsec long X-ray filament in the core of the cluster of galaxies A 1795. The feature coincides with an Hα+NII filament found by Cowie et al in the early 1980s and resolved into at least 2 U-band filaments by McNamara et al in the mid 1990s. The (emission-weighted) temperature of the X-ray emitting gas along the filament is 2.5 − 3 keV, as revealed by X-ray colou...
متن کاملX - ray active galactic nuclei in the core of the Perseus cluster
We present a study of the X-ray emission from the nuclei of galaxies observed in the core of the Perseus cluster in a deep exposure with Chandra. Point sources are found coincident with the nuclei of 13 early-type galaxies, as well as the central galaxy NGC 1275. This corresponds to all galaxies brighter than MB = −18 in the Chandra field. All of these sources have a steep power-law spectral co...
