Fundamental Plane of Groups and Clusters of Galaxies: Distances and Pecular Velocities of Superclusters of Galaxies on Small Scales
AbstractThis work is a continuation of the work of Kopylova and Kopylov published in 2016 on constructing the fundamental plane (FP) of groups and...

Galaxies and Clusters of Galaxies in Observations and Numerical Models
AbstractAn analysis of the properties of 1157 galaxies, groups and clusters of galaxies confirms the dependence of the virial velocity on the halo...

Satellites around Edge-on Galaxies. I. Dynamical Masses
AbstractWe have undertaken a search for satellites around edge-on galaxies in the EGIPS catalog, which contains 16 551 objects with declinations...

Evolutionary paths of active galactic nuclei and their host galaxies
The tight correlations between the masses of supermassive black holes (BHs) and the properties of their host galaxies suggest that BHs co-evolve with...

Dilution of chemical enrichment in galaxies 600 Myr after the Big Bang
The evolution of galaxies throughout the last 12 Gyr of cosmic time has followed a single, universal relation that connects star-formation rates...

A Search for New Dwarf Galaxies Outside the Nearby Groups
We undertook a search for new nearby dwarf galaxies outside the known groups in the Local Volume using the data on DESI Legacy Imaging Surveys. In a...

Distinct distributions of elliptical and disk galaxies across the Local Supercluster as a ΛCDM prediction
Galaxies of different types are not equally distributed in the Local Universe. In particular, the supergalactic plane is prominent among the...

Spectroscopic confirmation of four metal-poor galaxies at z = 10.3–13.2
Finding and characterizing the first galaxies that illuminated the early universe at cosmic dawn is pivotal to understand the physical conditions and...

Fact: Many SCUBA Galaxies Harbour AGNs
Deep SCUBA surveys have uncovered a large population of ultra-luminous galaxies at z>1. These sources are often assumed to be starburst galaxies, but...
