Is the observable Universe consistent with the cosmological principle?

PK Aluri, P Cea, P Chingangbam… - … and Quantum Gravity, 2023 - iopscience.iop.org
The cosmological principle (CP)—the notion that the Universe is spatially isotropic and
homogeneous on large scales—underlies a century of progress in cosmology. It is …

Mapping extreme-scale alignments of quasar polarization vectors

D Hutsemékers, R Cabanac, H Lamy… - Astronomy & …, 2005 - aanda.org
Based on a new sample of 355 quasars with significant optical polarization and using
complementary statistical methods, we confirm that quasar polarization vectors are not …

Updating the (supermassive black hole mass)–(spiral arm pitch angle) relation: a strong correlation for galaxies with pseudobulges

BL Davis, AW Graham, MS Seigar - Monthly Notices of the Royal …, 2017 - academic.oup.com
We have conducted an image analysis of the (current) full sample of 44 spiral galaxies with
directly measured supermassive black hole (SMBH) masses, M BH, to determine each …

Searching for rotating galaxy clusters in SDSS and 2dFGRS

HS Hwang, MG Lee - The Astrophysical Journal, 2007 - iopscience.iop.org
We present the results of a search for galaxy clusters that show an indication of global
rotation using a spectroscopic sample of galaxies in SDSS and 2dFGRS. We have …

Is the universe rotating?

SC Su, MC Chu - The Astrophysical Journal, 2009 - iopscience.iop.org
Models of a rotating universe have been studied widely since the work of Gödel, who
showed an example that is consistent with general relativity. By now, the possibility of a …

A conjecture on the neutrality of matter

L Campanelli - Foundations of Physics, 2021 - Springer
Elaborating on an old conjecture by Blackett, we formulate a new conjecture about the
neutrality of matter according to which any physical system possesses an active electric …

Global and local effects of rotation: Observational aspects

W Godłowski - International Journal of Modern Physics D, 2011 - World Scientific
In this paper we discussed the observational aspects of rotation in the Universe on different
scales. We show dependence between the angular momentum of the structures and their …

Rotation of the Universe at different cosmological epochs

LM Chechin - Astronomy Reports, 2016 - Springer
A step-by-step foundation for the differential character of the Universe's rotation is presented.
First, invoking the concept of spacetime foam with spin, it is reasonable to assume that the …

Dark energy from dynamical projective connections

S Brensinger, K Heitritter, VGJ Rodgers… - … and quantum gravity, 2020 - iopscience.iop.org
We further develop the gravitational model, Thomas-Whitehead gravity (TW Gravity), that
arises when projective connections become dynamical fields. TW Gravity has its origins in …

On physical foundations and observational effects of cosmic rotation

YN Obukhov - arXiv preprint astro-ph/0008106, 2000 - arxiv.org
An overview of the cosmological models with expansion, shear and rotation is presented.
Problems of the rotating models are discussed, their general kinematic properties and …
