Feedback from Active Galactic Nuclei in Galaxy Groups
Universe, 2021 The co-evolution between supermassive black holes and their environment is most directly traced by the hot atmospheres of dark matter halos. The cooling of the hot atmosphere supplies the central regions with fresh gas, igniting active galactic nuclei ...

Spatially Resolved Spectra of 3C Galaxy Nuclei [PDF]
The Astronomical Journal, 1998 We present and discuss visible-wavelength long-slit spectra of four low redshift 3C galaxies obtained with the STIS instrument on the Hubble Space Telescope. The slit was aligned with near-nuclear jet-like structure seen in HST images of the galaxies, to give unprecedented spatial resolution of the galaxy inner regions.

Quasi-periodic eruptions from galaxy nuclei
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT I consider quasi-periodic eruptions (QPEs) from galaxy nuclei. All the known cases fit naturally into a picture of accretion from white dwarfs (WDs) in highly eccentric orbits about the central black holes which decay through gravitational wave emission.

The Role of AGN in Luminous Infrared Galaxies from the Multiwavelength Perspective
Universe, 2022 Galaxy mergers provide a mechanism for galaxies to effectively funnel gas and materials toward their nuclei and fuel the central starbursts and accretion of supermassive black holes.

The Astrophysical Journal, 2023 The origin of the low-ionization nuclear emission-line region (LINER) prevalent in local galaxies and its relationship with supermassive black holes have been debated for decades.

Galaxies with Binary Nuclei [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractIt is known that among active galaxies (AG) with strong emission lines (UV-galaxies, Sy1 and Sy2, Markarian and Kazarian galaxies, radio-galaxies, QSOs host galaxies and so on) there is a large percentage of objects with double and multiple (or complex) nuclei.

SDSS-IV MaNGA: How Galaxy Interactions Influence Active Galactic Nuclei
The Astrophysical Journal, 2023 We present a comparative study of active galactic nuclei (AGN) between galaxy pairs and isolated galaxies with the final data release of the MaNGA integral field spectroscopic survey.

Active galactic nuclei and galaxy interactions [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 We perform a statistical analysis of active galactic nucleus (AGN) host characteristics and nuclear activity for AGNs in pairs and without companions. Our study concerns a sample of AGNs derived from the Sloan Digital Sky Survey Data Release 4 data by Kauffmann et al. and pair galaxies obtained from the same data set by Alonso et al.

Universe, 2023 Eicheon properties are discussed. It is shown that the eicheon surface allows setting a boundary condition for the vacuum polarization and obtaining a solution describing the dark matter tail in the Milky Way Galaxy. That is, the dark matter in the Milky
