The Atacama Cosmology Telescope: DR6 constraints on extended cosmological models

Journal of Cosmology and Astroparticle Physics
We use new cosmic microwave background (CMB) primary temperature and polarization anisotropy measurements from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) to test foundational assumptions of the standard cosmological model, ΛCDM, and set ...

Some Relativistic Cosmological Models

General Relativity and Gravitation, 1998
The author's dissertation from 1966 is published here for the first time in a journal. The now famous ``Kantowski-Sachs models'' in cosmology were deduced under the supervisorship of R. Sachs. The commutation relations and Killing equations then require the metric to have the following form \[ ds^2= dt^2- X(t)^2 dr^2- Y(t)^2 g_{AB} dx^A dx^B \qquad (A ...

Relativistic kinetics and cosmology. I

Soviet Physics Journal, 1980
A study is made of the problem of describing the cosmological expansion of a plasma in the framework of Chernikov's relativistic kinetic theory. It is shown that from the point of view of relativistic kinetics there are two stages in the evolution of the Universe in which thermodynamic equilibrium of the plasma is attained asymptotically: 1) the ...

Relativistic cosmology

1992
Abstract Cosmology is the study of the dynamical structure of the universe as a whole. As in most modelling exercises, we shall start by trying to find a very simple model of the universe. This is done by smoothing out all the irregularities in space and in time and concentrating simply on the gross features of the universe. So, to start
