When discovered in the 1960s, CMB radiation (the embers of the Big Bang) appeared to fill the sky uniformly, which raised a serious question: if CMB is uniform, how can there be galaxies today?
Hence, the discovery of CMB radiation ushered in one of the most-compelling frontiers of scientific investigation.
As CMB radiation crosses a galaxy cluster, it gets scattered by electrons in the intergalactic plasma, Ebeling says.
Owing to the Doppler effect, the CMB radiation temperature, measured by the 1st derivative of its monopole component, is lower than the monopole radiation temperature directly measured by FIRAS.
Hand used the 7,500 brightest galaxies from the BOSS data to uncover the predicted kSZ signal produced as galaxy clusters interacted with CMB radiation.
Just as the shape of a lens determines how light from an object is refracted to form an image, the curvature of space-time affects how CMB radiation traverses the universe en route to our microwave detectors.
In the present paper we extend the ideas of General Interactivity to the fractional derivatives, and so we can explain the outer flatness of rotation curves, last measures of SN Ia at high redshifts, the fluctuations in the CMB radiation and the classical cosmology theory.
That's because at earlier times, the universe was densest, and newly created clumps of electrons presented the greatest obstacle to the CMB radiation traveling through the clumps.
Until now, nobody had been able to find a way to efficiently search for signs of bubble universe collisions - and therefore proof of the multiverse - in the CMB radiation, as the disc-like patterns in the radiation could be located anywhere in the sky.
In addition to the precise age measurement, WMAP has been able to detect small acoustic oscillations (the cosmic equivalent to sound waves) in the CMB radiation, and the signature detected suggests primordial helium was generated in predicted quantities in the early stages of universal evolution.
Possible explanations have so far included a huge cloud that's soaking up CMB radiation, a gaping hole devoid of matter, or even the footprint of another universe that was once entangled with our own.
