ASCA Observations of a Nearby and Massive Galaxy Cluster Abell 3627
نویسندگان
چکیده
The results obtained from the ASCA observations of the cluster of galaxies Abell 3627 are presented. This cluster, located behind the Milky way, was recently found to be a nearby, X-ray bright and very rich cluster. Pointed observations onto the central region of the cluster gave a gas temperature of ∼ 7 keV and a metallicity of about 0.2 solar. An offset pointing to a substructure elongated to south-east of the cluster center gave a significantly lower temperature of ∼ 5 keV. The 2–10 keV luminosity within a radius of 40 (1.1 Mpc) is estimated to be 3.7 × 10 erg s. The X-ray data imply a cluster mass of about 4 × 10 M⊙ within 40 .

The cluster A3627 was recently recognized to be a very massive, nearby cluster in a galaxy survey close to the galactic plane. We are reporting on ROSAT PSPC observations of this object which confirm that the cluster is indeed very massive. The X-ray emission detected from the cluster extends over almost 1 degree in radius. The X-ray image is not spherically symmetric and shows indications of a...
متن کاملASCA and ROSAT observations of distant massive cooling flows
We present the results from a detailed ASCA/ROSATX-ray study of three distant, massive cooling flows; Zwicky 3146 (z = 0.291), Abell 1835 (z = 0.252) and E1455+223 (Zwicky 7160; z = 0.258). Using multiphase models fitted to the ASCA spectra, we determine values for the temperature, metallicity, luminosity and cooling rates in the clusters. These results are combined with deprojection analyses o...
متن کاملKpc X - Ray Tail in the Cluster a 3627
We present the discovery of a 70 kpc X-ray tail behind the small late-type galaxy ESO 137-001 in the nearby, hot (T=6.5 keV) merging cluster A3627, from both Chandra and XMM-Newton observations. The tail has a length-to-width ratio of ∼ 10. It is luminous (L 0.5−2keV ∼ 10 41 ergs s −1), with a temperature of ∼ 0.7 keV and an X-ray M gas of ∼ 10 9 M ⊙ (∼ 10% of the galaxy's stellar mass). We int...
متن کاملX - ray Properties of the Abell 644 Cluster of Galaxies
We use new ASCA observations and archival ROSAT Position Sensitive Proportional Counter (PSPC) data to determine the X-ray spectral properties of the intracluster gas in Abell 644. From the overall spectrum, we determine the average gas temperature to be 8.64 −0.56 keV, and an abundance of 0.32 ± 0.04 Z⊙. The global ASCA and ROSAT spectra imply a cooling rate of 214 −91 M⊙ yr −1. The PSPC X-ray...
متن کاملMultiwavelength Observations of a Seyfert 1 Galaxy Detected in ACO 3627
ACO 3627 is a rich, nearby cluster of galaxies at the core of the Great Attractor. At the low galactic latitude of b = −7.2 the galactic extinction is significant. Nevertheless, its proximity makes it a prime target for studies of environmental effects on its cluster members. Here, we report on a multi-wavelength study of a Seyfert 1 galaxy at 30 arcmin from the centre of ACO 3627. Its Seyfert ...
