Comment on "On the Origin of the Highest Energy Cosmic Rays" [PDF]
, 1998 We show that the photodisintegration of heavy cosmic ray nuclei with energies above 10^20 eV is dominated by interactions with photons from the cosmic microwave background radiation, rather than from infrared ones.

Photon-graviton conversion in a primordial magnetic field and the cosmic microwave background [PDF]
, 1996 We reconsider the effects of photon-graviton conversion in a primordial magnetic field upon the cosmic microwave background radiation. We argue that plasma effects make the photon-graviton conversion process negligible.Comment: Revtex, 3 pages. To appear

Different Explanations for the Cosmic Microwave Background Radiation
, 2021 In this research, the other reasonable explanations for the cosmic microwave background radiation is revealed. Due to the microwave resolution, it very roughly shows the image of galaxies in the universe. Moreover, the intensity measurement on each pixel of the image is the sum of the incident microwaves from different directions, so the microwave ...

From primordial quantum fluctuations to the anisotropies of the cosmic microwave background radiation [PDF]
, 2005 These lecture notes cover mainly three connected topics. In the first part we give a detailed treatment of cosmological perturbation theory. The second part is devoted to cosmological inflation and the generation of primordial fluctuations. In part three

POLAR: Instrument and Results [PDF]
, 2002 We describe the design, performance, and results of a polarimeter used to make precision measurements of the 2.7 K cosmic microwave background. In the Spring of 2000 the instrument searched for polarized emission in three microwave frequency bands ...

On parton distributions in a photon gas
, 2009 In some cases it may be useful to know parton distributions in a photon gas. This may be relevant, e.g., for the analysis of interactions of high energy cosmic ray particles with the cosmic microwave background radiation.
