Light Red Shift in Cosmic Background Photon Gas

Cosmic Background Radiation Due to Photon Condensation

It is shown that a collection of photons with nearly the same frequency exhibits a Bose ”condensation” type of phenomenon at about 3K corresponding to a peak intensity at a wave length of about 0.4cm. This could give a mechanism for the observed Cosmic Background Radiation, and also explain some curious features. It is a curious circumstance that the substitution of the cosmic microwave backgro...

Light-shift-modulated photon-echo.

We show that the AC-Stark shift (light-shift) is a powerful and versatile tool to control the emission of a photon-echo in the context of optical storage. As a proof-of-principle, we demonstrate that the photon-echo efficiency can be fully modulated by applying light-shift control pulses in an erbium-doped solid. The control of the echo emission is attributed to the spatial gradient induced by ...

Imaging the Low Red - shift Cosmic Web

The first image of a Cosmic Web, Lyman Limit System has just been made in HI emission within the Local Group filament connecting M31 and M33. The corresponding HI distribution function is in very good agreement with that of the QSO absorption lines, confirming the 30-fold increase in surface area expected between 10 cm and 10 cm. The critical observational challenge is crossing the “HI desert”,...

Resonant Photon-Graviton Conversion and Cosmic Microwave Background Fluctuations.

HI Imaging the Low Red-shift Cosmic Web

Only in recent years has the realization emerged that galaxies do not dominate the universal baryon budget but are merely the brightest pearls of an underlying Cosmic Web. Although the gas in these inter-galactic filaments is moderately to highly ionized, QSO absorption lines have shown that the surface area increases dramatically in going down to lower HI column densities. The first image of t...
