A BeppoSAX observation of the cooling flow cluster Abell 2029
نویسنده
چکیده
We present results from a BeppoSAX observation of the cooling flow cluster Abell 2029. The broad band spectrum (2–35 keV) of the cluster, when fitted with a model including a cooling flow component and a one temperature thermal component, yields a temperature of 8.3±0.2 keV and a metal abundance of 0.46±0.03 in solar units, for the latter. No evidence of a hard X-ray excess is found in the PDS spectrum. By performing a spatially resolved spectral analysis we find that the projected temperature and abundance drop with increasing radius, going from ∼ 8 keV and 0.5 (solar units) at the cluster core to ∼ 5 keV and 0.2 (solar units) at about 1.2 Mpc.

The Complex Cooling Core of Abell 2029: Radio and X-ray Interactions
We present an analysis of Chandra observations of the central regions of the cooling flow cluster Abell 2029. We find a number of X-ray filaments in the central 40 kpc, some of which appear to be associated with the currently active central radio galaxy. The outer southern lobe of the steep-spectrum radio source appears to be surrounded by a region of cool gas and is at least partially surround...
متن کاملInteraction in Abell 2256: The BeppoSAX View.
We present results from a spatially resolved spectral analysis of the merging cluster Abell 2256. The long integration time (135 ks) and the good spatial resolution of the Medium-Energy Concentrator/Spectrometer on board BeppoSAX allow us to derive a new and substantially improved measurement of the temperature structure. We find that, within a central region of the cluster, where the effects o...
متن کاملX-ray Spectral Properties of the Cluster Abell 2029
We have analyzed ASCA and ROSAT PSPC spectra and images of the galaxy cluster Abell 2029. The ASCA spectra of the cluster indicate that the gas temperature declines with radius. The PSPC image shows that the cluster is very regular and smooth. Also, there is no significant evidence for any irregularities in the temperature distribution in the cluster, as would be produced by a subcluster merger...
متن کاملBeppoSAX observation of the cluster Abell 970
We report new results on the cluster of galaxies Abell 970 obtained from X-ray observation with BeppoSAX. Our analysis of the BeppoSAX MECS and LECS data in the range [0.15–10] keV reveals a mean cluster gas temperature of kT = 4.46 −0.15 , a metallicity of Z = 0.31 +0.05 −0.04Z , and an interstellar hydrogen absorption density column of NH = 6.05 +1.29 −0.97 × 1020cm−2. Moreover, we obtained a...
متن کاملSpatially resolved spectroscopy of the cooling flow cluster PKS 0745-191 with BeppoSAX
We present results from a BeppoSAX observation of the cooling flow cluster PKS 0745−191 (z=0.1028). By performing spatially resolved spectroscopy, we find that the projected temperature profile is consistent with being constant. We can rule out, at more than the 99% confidence level, a temperature decrement of a factor 2 when going from the cluster core out to 1.2 Mpc. On the contrary, the proj...
