An Observer moving in the 3° K Radiation Field
TL;DR: In this article, it is assumed that the second observer, using the same radiometer as the first, would receive more power from the direction in which he is moving, but, according to a defective derivation by Condon and Harwit, a detector receives less power from an approaching source than from a receding one, if hv/kT < 1.60.

Spektrum und Anisotropiegrad der 3 °K-Strahlung bei anisotroper kosmologischer Expansion
TL;DR: In this paper, the propagation of electromagnetic radiation which interacts with matter through elastic electron scattering in arbitrary gravitational fields allow to draw conclusions relevant to the thermal history of the 3 °K microwave background: Provided, a thermalization at some instant t = t1 in the past has established at this time a Planckian photon distribution function (possibly with the temperature T depending on the propagation direction and on space coordinates).

Energy Flux from the 3° K Radiation
Peter T. Landsberg,K.A. Johns +1 more
TL;DR: In this paper, the authors make precise statements concerning black body radiation, isotropic in a frame S0, which moves with velocity v in the observer's frame S. This is of interest in connexion with the problem of measuring the Earth's velocity through the 3° K cosmic background radiation field and assigning a temperature to a moving black body.
