Thermodynamics and two-fluid cosmological models
TL;DR: In this paper, exact solutions of Einstein's field equations and the laws of thermodynamics are presented in which both a comoving radiative perfect fluid and a non-comoving imperfect fluid act as the source of the gravitational field as represented by the flat FRW line element, and the tilting velocity of the imperfect fluid is associated with the peculiar velocity of our local cluster of galaxies relative to the cosmic microwave background.

A Measurement of excess antenna temperature at 4080-Mc/s
Arno A. Penzias,Robert W. Wilson +1 more
TL;DR: In this paper, the effective zenith noise temperature of the 20-foot horn-reflector antenna (Crawford, Hogg, and Hunt 1961) at the Crawford Hill Laboratory, Holmdel, New Jersey, at 4080 Mc/s has yielded a value about 3.5 K higher than expected.

The Thermodynamics of Irreversible Processes. III. Relativistic Theory of the Simple Fluid
TL;DR: In this paper, it was shown that the first law of thermodynamics is a scalar equation, and not the fourth component of the energy-momentum principle, and temperature and entropy also prove to be scalars.

A Homogeneous Universe of Constant Mass and Increasing Radius accounting for the Radial Velocity of Extra-galactic Nebulæ
TL;DR: Lemaitre as discussed by the authors was the first one to understand the recent observations on the recession velocities of galaxies as a natural consequence of dynamical cosmological solutions of Einstein's field equations.

Detection of Anisotropy in the Cosmic Blackbody Radiation
TL;DR: Anisotropy has been detected in the cosmic blackbody radiation with a 33GHz (0.9 cm) twin-antenna Dicke radiometer flown to an altitude of 20 km aboard a U-2 aircraft as mentioned in this paper.
