Using ASCA data, we have measured the electron temperature in Abell 2163 out to 1.5 h −1 Mpc (3/4 of the virial radius, or 10a x , where a x is the X-ray core-radius) from the center, in three radial bins. The obtained temperatures are 12.2 −0.9 keV in the 0–3 a x (0–3.5 ′), 3–6 a x and 6–13 a x spherical shells, respectively 5. Formally applying the hydrostatic equilibrium and spherical symmet...
متن کاملThe giant radio halo in Abell 2163
New radio data is presented for the rich cluster Abell 2163. The cluster radio emission is characterized by the presence of a radio halo, which is one of the most powerful and extended halos known so far. In the NE peripheral cluster region, we also detect diffuse elongated emission, which we classify as a cluster relic. The cluster A2163 is very hot and luminous in X-ray. Its central region is...
متن کاملSpectral index maps of the radio halos in Abell 665 and Abell 2163
New radio data at 330 MHz are presented for the rich clusters Abell 665 and Abell 2163, whose radio emission is characterized by the presence of a radio halo. These images allowed us to derive the spectral properties of the two clusters under study. The integrated spectra of these halos between 0.3 GHz and 1.4 GHz are moderately steep: α1.4 0.3 = 1.04 and α1.4 0.3 = 1.18, for A665 and A2163, re...
متن کاملA weak lensing analysis of the Abell 2163 cluster . ?
Aims. This paper is aimed at measuring the main physical properties (mass, velocity dispersion, and total luminosity) of the cluster Abell 2163. Methods. Weak lensing analysis is applied to a deep, one square degree r-band CFHT-Megacam image of the Abell 2163 field. The observed shear is fitted with Single Isothermal Sphere and Navarro-Frenk-White models to obtain the velocity dispersion and th...
متن کاملA Weak Gravitational Lensing and X - ray Analysis of Abell 2163
We report on the detection of dark matter in the cluster of galaxies Abell 2163 using the weak gravitational distortion of background galaxies, and an analysis of the X-ray emission from the cluster. We find that while the qualitative distributions of the cluster light and the dark matter are similar — shallow and extended, with significant substructure — the X-ray morphology shows a more regul...
