beam] is the azimuth of the laser beam and coincides with the CMBR apex azimuth when it is on the horizon.
As we know the equatorial coordinates of the CMBR ([alpha], [delta])=([11.
The CMBR was a prediction of the work of George Gamow, Ralph Alpher, Hans Bethe and Robert Herman on the Big Bang nucleosynthesis [11,12], and was discovered later in 1964 by Penzias and Wilson.
It starts with the fluctuations in the density of the universe seen in the CMBR, then models the way that matter collapses into today's galaxies over the subsequent 13 billion years.
The continuous fluctuation of energy in the quantum field which are believed to be responsible for tiny variations of temperature in the CMBR provided the 'seeds' from which stars and galaxies were formed.
If universe is accelerating, just like "rate of stretching of a rubber band of infinite length" CMBR photon wavelength stretches and CMBR temperature decreases.
Finally, in 2002, Fixsen and Mather [43] advance that "the measured deviation from this spectrum are 50 parts per million (PPM, rms) of the peak brightness of the CMBR spectrum, within the uncertainty of the measurement".
Sunyaev identified the extraordinary possibility of using observations of baryon acoustic oscillations (BAO) -- oscillations resulting from primordial fluctuations in the early universe that are detectable in the CMBR -- for quantitative analysis of cosmological parameters of the expanding universe.

The proposed explanation is a far simpler one than the requirement to balance photon to proton ratios in the theorized early Universe of the Big Bang, with the added concern of an inflationary period to allow smoothness in the CMBR.
At this section we consider the anisotropic effect which may be useful for analyzing the anisotropy of CMBR spectrum, see Fig.
