Relative distances and peculiar velicities of 140 groups and clusters of galaxies at low redshifts: the Hubble diagram
Flera G. Kopylova, Alexander I. Kopylov
To determine the relative distances and peculiar velocities of 140 groups and clusters of galaxies at low redshifts ( < 0.12), we used the fundamental plane (FP) of early-type g…

Fundamental Plane of Groups and Clusters of Galaxies: Distances and Peculiar Velocities of Superclusters of Galaxies on Small Scales
Flera G. Kopylova, Alexander I Kopylov
This work is a continuation of the work of Kopylova and Kopylov (2016) to build a fundamental plane (FP) of groups and clusters of galaxies -- here a sample of galaxies systems is…

Halo Radius (Splashback Radius) of Groups and Clusters of Galaxies on small scales
Flera G. Kopylova, Alexander I. Kopylov
We report the results of a study of the distribution of galaxies in the projection along the radius () for 157~groups and clusters of galaxies in the local Univer…
