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
Various classification schemes for galaxies are introduced, including the Hubble-de Vaucouleurs sequence, as well as other classes of galaxy:... -
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...

Astrocladistics: evolutionary classification for galaxies of the M81 group
This work deals with the classification of galaxies based on the evolutionary and hierarchical development of their parameters. We apply the...

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...

A departure from the mass–metallicity relation in merging galaxies due to an infall of metal-poor gas
Heavy element accumulation and stellar mass assembly are fundamental processes in the formation and evolution of galaxies. However, the key elements...

Baryonic properties of nearby galaxies across the stellar-to-total dynamical mass relation
In the standard cosmological model, the assembly of galaxies is primarily driven by the growth of their host dark matter halos. At the centre of...

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...

Observational Manifestations of First Galaxies in the Far Infrared Range
High-redshift galaxies ( z ≳ 9) are currently observed in the near-infrared (1.4-2 μm), mid-infrared (IR) (5-28.8 μm), and submillimeter (500-1000 μm)...

Making Real Galaxies
Having developed many of the tools necessary to understand the physical processes involved in the formation of galaxies, this chapter addresses the... -
The Relation Between Stellar Populations and Light Profiles in Early–Type Galaxies
Early-type (E/SO) galaxies follow tight relations such as the Fundamental Plane, the Color-Magnitude Relation or the Mg2–σ relation (Bender et al.... -
Low gas-phase metallicities of ultraluminous infrared galaxies are a result of dust obscuration
Optical spectroscopic measurements show that gas in dusty, starbursting galaxies known as ultraluminous infrared galaxies (ULIRGs) in the local...

Cosmic ray feedback in galaxies and galaxy clusters
Understanding the physical mechanisms that control galaxy formation is a fundamental challenge in contemporary astrophysics. Recent advances in the...

Possibilities of identifying members from Milky Way satellite galaxies using unsupervised machine learning algorithms
A detailed study of stellar populations in Milky Way (MW) satellite galaxies remains an observational challenge due to their faintness and fewer...

Photometric studies on the host galaxies of gamma-ray bursts using 3.6m Devasthal optical telescope
In this paper, we present multi-band photometric observations and analysis of the host galaxies for a sample of five interesting gamma-ray bursts...

Environmental Dependence of Different Colors of Active Galactic Nucleus (AGN) Host Galaxies
Using the apparent-magnitude limited active galactic nucleus (AGN) host galaxy sample of the Sloan Digital Sky Survey Data Release 12 (SDSS DR12), we...

Clusters of Galaxies
Clusters of galaxies play a key role in astrophysical cosmology. The richest clusters are included in the Abell Catalogues of Rich Clusters of... -
Directly Detecting the Evolution of Early-Type Galaxies
We describe observations focused on understanding the epochs and timescales of the formation and evolution of early-type galaxies, particularly those... -
X-ray Binaries in External Galaxies
X-ray appearance of normal galaxies is mainly determined by X-ray binaries powered by accretion onto a neutron star or a stellar mass black hole....
