Big bang of the brane universe [PDF]

, 2001
Big bang of the Friedmann-Robertson-Walker (FRW)-brane universe is studied. In contrast to the spacelike initial singularity of the usual FRW universe, the initial singularity of the FRW-brane universe is point-like from the viewpoint of causality ...

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

Journal 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

St. 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.

Making a Universe [PDF]

, 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.

Universal Sequences [PDF]

Applicable 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 ...

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

, 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 ...

Entropic Accelerating Universe [PDF]

, 2010
To accommodate the observed accelerated expansion of the universe, one popular idea is to invoke a driving term in the Friedmann-Lemaitre equation of dark energy which must then comprise 70% of the present cosmological energy density.

Unveiling the gravitational universe at μ-Hz frequencies [PDF]

Experimental astronomy (Print), 2019
We propose a space-based interferometer surveying the gravitational wave (GW) sky in the milli-Hz to μ-Hz frequency range. By the 2040s, the μ-Hz frequency band, bracketed in between the Laser Interferometer Space Antenna (LISA) and pulsar timing arrays,
