Dark Matter in the Milky Way as the F-Type of Vacuum Polarization
Physical Sciences Forum, 2023 Dark matter in the Milky Way is explained by the F-type of vacuum polarization, which could represent dark radiation. A nonsingular solution for dark radiation exists in the presence of eicheon (i.e., black hole in old terminology) in the galaxy’s center.

Merging Galaxies with Active Nuclei [PDF]
Symposium - International Astronomical Union, 1999 We are investigating a sample of nearby interacting and merging galaxies showing starburst properties and/or nonthermal nuclear activity (e.g. Mrk 231, Mrk 739, Mrk 1027, NGC 2992, Arp 92).

Properties of Galaxies with Peculiar Nuclei [PDF]
Publications of the Astronomical Society of the Pacific, 1967 In a former note (Sersic and Pastoriza 1965) we published the results of a survey of bright southern galaxies which were inspected for peculiarities in their nuclei. Although the sample was small ( 35 galaxies) it suggested a relationship between the existence of a bar and the presence of abnormal features in their nuclei.

Double-nucleus elliptical MCG-01-12-005 in an X-ray emitting cluster of galaxies [PDF]
, 2015 The scenario of galaxy formation is believed to follow a structure that builds up from the bottom, with large galaxies being formed by several merging episodes of smaller ones.

A Multiwavelength Study of Active Galactic Nuclei in Post-merger Remnants
The Astrophysical Journal, 2023 We investigate the role of galaxy mergers in triggering active galactic nuclei (AGN) in the nearby universe. Our analysis is based on a sample of 79 post-merger remnant galaxies with deep X-ray observations from Chandra/XMM-Newton capable of detecting a ...

Interacting Nuclei in Distant Galaxies [PDF]
International Astronomical Union Colloquium, 1990 The interaction of galaxies not only occurs in galactic scales, but also may be linked to the binary cores in active galactic galaxies. The presence of a binary in the center of galaxies was suggested by Begelman, Blandford and Rees (1980). Gaskell (1983) suggests that supermassive binaries may account for the observed structure of emission line ...

The impact of stripped Nuclei on the Super-Massive Black Hole number density in the local Universe [PDF]
, 2018 The recent discovery of super-massive black holes (SMBHs) in the centers of high-mass ultra compact dwarf galaxies (UCDs) suggests that at least some UCDs are the stripped nuclear star clusters of lower mass galaxies.

Galaxies and Their Nuclei [PDF]
Highlights of Astronomy, 1974 Our Extraordinary General Assembly is devoted to the memory of one of the greatest men of science to the genial Polish astronomer - Nicolaus Copernicus. The main service of Copernicus which has made his name immortal was in finding the correct interpretation of the planetary motions we observe.

Active Galactic Nuclei among Polar-Ring Galaxies [PDF]
Astronomy Letters, 2020 Based on SDSS data, we consider the fraction of active galactic nuclei among polar-ring galaxies. We have found evidence for an excess of Seyfert galaxies and LINERs among polar-ring galaxies compared to ordinary objects. The observed nuclear activity of polar-ring galaxies may be associated with the accretion of gas from the region of the polar ...
