The Scaled Universe [PDF]

open access: yes, 1999
It is shown that the mysterious quantum prescription of microphysics has analogues at the scale of stars, galaxies and superclusters, the common feature in all these cases being Brownian type fractality.

Induced gravitational waves as a probe of thermal history of the universe [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2020
The scalar perturbation induced gravitational waves are a probe of the primordial density perturbation spectrum on small scales. In this paper, we show that they can also probe the thermal history of the universe. We assume the universe underwent a stage

About its own time and the mass of the universe

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics, 2021
A modification of the quantum theory of gravity in the case of a closed universe, in which the dynamics is reduced to the motion in the orbit of a group of general covariance, is proposed.

The Adventures of Road Workers (1974–1980): National Specificity of the Georgian Trio [PDF]

open access: yesХудожественная культура
The author focuses on a series of short films about road workers, created in 1974–1980 by different directors of the Georgia Film studio based on the scripts by Rezo Gabriadze.

Universal Sequences [PDF]

open access: yesApplicable Algebra in Engineering, Communication and Computing, 1997
Untersucht wird wie lang mindestens eine \((0,1)\)-Test-Folge sein muß, um darin für jedes \(m\) (mit \(k\leq m\leq n\) bei vorgegebenen \(k,n)\) mit \(2^{k}\) Teilfolgen davon alle \((0,1)\)-Folgen der Länge \(k\) zu erhalten, wobei die Teilfolgen spätestens mit dem jeweils \(m\)-ten Folge-Element der Test-Folge vom Teilfolgen-Beginn an endet ...

Stationary Universe

open access: yes, 1993
If the Universe contains at least one inflationary domain with a sufficiently large and homogeneous scalar field, then this domain permanently produces new inflationary domains of all possible types.

Introducing the Illustris Project: simulating the coevolution of dark and visible matter in the Universe [PDF]

open access: yes, 2014
We introduce the Illustris Project, a series of large-scale hydrodynamical simulations of galaxy formation. The highest resolution simulation, Illustris-1, covers a volume of $(106.5\,{\rm Mpc})^3$, has a dark mass resolution of ${6.26 \times 10^{6 ...

Making a Universe [PDF]

open access: yes, 2006
For understanding the origin of anisotropies in the cosmic microwave background, rules to construct a quantized universe is proposed based on the dynamical triangulation method of the simplicial quantum gravity.

The evidence for a spatially flat Universe [PDF]

open access: yes, 2020
We revisit the observational constraints on spatial curvature following recent claims that the Planck data favour a closed Universe. We use a new and statistically powerful Planck likelihood to show that the Planck temperature and polarization spectra ...
