ELLIPTICITIES OF ELLIPTICAL GALAXIES IN DIFFERENT ENVIRONMENTS
The Astrophysical Journal, 2016 ABSTRACT We studied the ellipticity distributions of elliptical galaxies in different environments. From the ninth data release of the Sloan Digital Sky Survey, we selected galaxies with absolute -band magnitudes between −21 and −22.

The Open Journal of AstrophysicsAlignments of disc galaxies were thought to result from tidal torquing, where tidal field of the cosmic large-scale structure exert torquing moments onto dark matter haloes, determining their angular momentum and ultimately the orientation of galactic ...

Galactic Structures from Gravitational Radii
Galaxies, 2018 We demonstrate that the existence of a Noether symmetry in f ( R ) theories of gravity gives rise to an additional gravitational radius, besides the standard Schwarzschild one, determining the dynamics at galactic scales.

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model
Systems Research and Behavioral Science, Volume 43, Issue 3, Page 1212-1228, May/June 2026.ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

New Analysis of Dark Matter in Elliptical Galaxies
, 2022 We investigate a correlation between the dark matter content of elliptical galaxies and their ellipticity that was initially reported in 2014. We use new determinations of dark matter and ellipticities that are posterior to that time.

A Photometric Study of Giant Ellipticals and Their Stellar Halos With VST
Galaxies, 2017 Observations of diffuse starlight in the outskirts of galaxies are thought to be a fundamental source of constraints on the cosmological context of galaxy assembly in the Λ CDM model.

SIMULATIONS OF LARGE-SCALE GASEOUS STRUCTURES WITH SPH
Odessa Astronomical Publications, 2017 A computer programme based on the 3D SPH approach is described. Some numerical results are presented: the formation of gaseous ring around an SO galaxy due to the stripping of a gas-rich donor system.

Chemodynamical Simulations of Elliptical Galaxies
, 2007 We review recent developments in the field of chemodynamical simulations of elliptical galaxies, highlighting (in an admittedly biased fashion) the work conducted with our cosmological N-body/SPH code ...

Core Formation by Binary Scouring and Gravitational Wave Recoil in Massive Elliptical Galaxies
The Astrophysical JournalScouring by supermassive black hole (SMBH) binaries is the most accepted mechanism for the formation of the cores seen in giant elliptical galaxies. However, an additional mechanism is required to explain the largest observed cores.
