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...

Radio Properties of the Low-Redshift Isolated Galaxies with Active Nuclei
AbstractThe properties of 61 isolated galaxies with active nuclei (isolated AGNs) in the radio frequency range at redshifts z < 0.05 have been...

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...
-
Luminosities of Radio-Loud Active Galaxies
We investigate the host galaxy luminosities of three different samples of radio loud active nuclei at z<0.5 including BL Lac Objects (BLLs), Radio...

The Evolution of Galaxies and Active Galaxies with Cosmic Epoch
Evolutionary changes in the properties of all classes of extragalactic systems with cosmic epoch have been observed in all accessible astronomical...

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

The Environmental Dependence of the Stellar Velocity Dispersion of Active Galactic Nucleus (AGN) Host Galaxies and Dependence of the Clustering Properties of AGN Host Galaxies on the Stellar Velocity Dispersion
We use two volume-limited active galactic nucleus (AGN) host galaxy samples constructed by Deng & Wen [47], and explore the environmental dependence...

On a Possible Mechanism for the Start or Resumption of Activity of Radio Galaxies in Clusters of Galaxies
We study the close proximity of the well-known and well-studied 3C31 class FRI radio galaxy in order to reveal the influence of the environment on an...

Active Galaxies in the Mid Infrared: Ground-Based versus Space-Born Observations
We investigate the mid-infrared radiation of galaxies that are powered by a starburst or by an AGN. For this end, we compare the spectra obtained at...

Compact Galaxies with Active Star Formation from the SDSS Data Release 16: Star-Formation Rates Based on the Luminosities of Forbidden Emission Lines in the Optical Range
AbstractWe obtained equations for determining the star-formation rate in local compact star-forming galaxies from the SDSS Data Release 16 using...

Evidence for Massive Black Holes in the Nuclei of Active Galaxies from Gamma-Ray Observations
According to our present knowledge, Active Galactic Nuclei (AGNs) consist of massive black holes which accrete matter from their environments. By...

Environmental Dependence of All the Five Band Luminosities 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...

An increase in black hole activity in galaxies with kinematically misaligned gas
External accretion events such as a galaxy merger or the accretion of gas from the immediate environment of a galaxy can create a large misalignment...

Effect of dark matter haloes on the orbital and escape dynamics of barred galaxies
This work examines the effect of dark matter haloes on the fate of bar-driven esca** patterns in disc galaxies. In this study, a three-dimensional...

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...

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...

The nature of compact radio sources: the case of FR 0 radio galaxies
Radio-loud compact radio sources (CRSs) are characterised by morphological compactness of the jet structure centred on the active nucleus of the...

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...

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...
