Abstract
The structure of the A1035 cluster of galaxies (10h32m + 40°13′, cz ∼ 22000 kms−1), which exhibits a bimodal distribution of galaxy radial velocities (ΔV ≈ 3000 kms−1), is analyzed using three methods of determining the relative distances to clusters from early-type galaxies: the Kormendy relation corrected for the dependence of residuals on galaxy magnitude, the photometric plane, and the fundamental plane. We use the data obtained with the l-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences and SDSS (DR5) data to show that A1035 consists of two gravitationally unbound independent clusters. These clusters with the velocity dispersions of 566 km s−1 and 610 km s−1 and masses within R 200 equal to 2.7 · 1014 and 3.5 · 1014 M ⊙, respectively, obey the Hubble law.
