Weak lensing evidence for a filament between A222/A223

چکیده
We present a weak lensing analysis and comparison to optical and Xray maps of the close pair of massive clusters A222/223. Indications for a filamentary connection between the clusters are found and discussed.

Weak lensing evidence for a filament between the clusters A 222 and A 223 and its quantification ⋆
We present a weak lensing analysis of the double cluster system Abell 222 and Abell 223. The lensing reconstruction shows evidence for a possible dark matter filament connecting both clusters. The case for a filamentary connection between A 222/223 is supported by an analysis of the galaxy density and X-ray emission between the clusters. Using the results of N-body simulations, we try to develo...

متن کاملSpectroscopy of the neighboring massive clusters Abell 222 and Abell 223
We present a spectroscopic catalog of the neighboring massive clusters Abell 222 and Abell 223. The catalog contains the positions, redshifts, R magnitudes, V −R color, as well as the equivalent widths for a number of lines for 183 galaxies, 153 of them belonging to the A 222 and A 223 system. We determine the heliocentric redshifts to be z = 0.2126 ± 0.0008 for A 222 and z = 0.2079 ± 0.0008 fo...
متن کاملIs Gravitational Lensing by Intercluster Filaments Always Negligible?
Intercluster filaments negligibly contribute to the weak lensing signal in General Relativity (GR), γN ∼ 10−4−10−3. In the context of relativistic Modified Newtonian Dynamics (MOND) (Bekenstein 2004), however, a single filament inclined by ≈ 45◦ from the line of sight can cause substantial distortion of background sources pointing towards the filament’s axis (κ = γ = (1 − A−1)/2 ∼ 0.01); this i...
