Temperature Structure in Abell 1367
We study the temperature structure of the rich cluster of galaxies Abell 1367 using two independent methods of correcting for the ASCA PSF. The results of the two methods are in excellent agreement and give solid evidence of a strong and localized shock in the intracluster medium (ICM). Our analysis suggests that we are observing the merger of two subclusters. We find that the lower luminosity ...
متن کاملMultiple merging in the Abell cluster 1367 . ⋆
We present a dynamical analysis of the central ∼ 1.3 square degrees of the cluster of galaxies Abell 1367, based on 273 redshift measurements (of which 119 are news). From the analysis of the 146 confirmed cluster members we derive a significantly non-Gaussian velocity distribution, with a mean location CBI = 6484±81 km s −1 and a scale SBI = 891 ± 58 km s −1. The cluster appears elongated from...
متن کاملSpitzer observations of Abell 1763
Context. The study of galaxy luminosity functions (LFs) in different environments provides powerful constraints on the physics of galaxy evolution. The infrared (IR) LF is a particularly useful tool since it is directly related to the distribution of galaxy star-formation rates (SFRs). Aims. We aim to determine the galaxy IR LF as a function of the environment in a supercluster at redshift 0.23...
متن کاملChandra observations of Abell 2199
We present results from an analysis of two Chandra observations of the rich, nearby galaxy cluster Abell 2199. We find evidence (having corrected for projection effects) for radial gradients in temperature and metallicity in the X-ray emitting gas: the temperature drops from kT ∼ 4.2 keV at R=200 kpc to 1.6 keV within R=5 kpc of the centre. The metallicity rises from ∼ 0.3 solar at R=200 kpc to...
متن کاملCO in late – type galaxies within the central region of Abell 1367
We present CO (J = 1 → 0) and CO (J = 2 → 1) spectra for 19 bright, late–type galaxies (spirals) in the central region of the galaxy cluster Abell 1367 (z = 0.02) from observations made with the IRAM 30–m telescope. All 19 spirals were observed at the position of their optical center and for a subset, at multiple positions. For each spiral the integrated CO (J = 1 → 0) intensity from the centra...
