Sentences with phrase «cosmological microwave background»

«Ongoing observations of cosmological microwave background and large scale structures have achieved impressive precision, from which valuable information about primordial density perturbations can be extracted,» said Yi Wang, a co-author of the paper and an assistant professor at HKUST's department of physics.

Since 1965 and the discovery of the Cosmological Microwave background (CMB) by Penzias and Wilson, we know that Lemaître was wrong.

Recent cosmic microwave background (CMB) measurement not only demonstrate the existence of the cosmological constant, but the value of the constant.

And measurements of cosmological parameters — the fraction of dark energy and matter, for example — are generally consistent, whether they are made using the light from galaxies or the cosmic microwave background.

This «Cosmological Principle» is backed up by observations of the early universe and its microwave background signature, seen by the WMAP and Planck satellites.

And with the discovery of the cosmic microwave background in the 1960s, the big bang theory of the universe's birth assumed the starring role on the cosmological stage — providing cosmologists with one big answer and many new questions.

By measuring subtle variations in the cosmic microwave background (CMB), the remnant radiation from the early universe that pervades the sky, WMAP refined the estimated age of the universe (13.7 billion years, give or take), among other key cosmological parameters.

Previously, the most precise test of cosmological models came from measurements with the European Space Agency's Planck satellite of what is known as the cosmic microwave background (CMB)-- a faint glow in the sky emitted 380,000 years after the Big Bang.

KIPAC faculty member Risa Wechsler, a founding member of DES, said, «For the first time, the precision of key cosmological parameters coming out of a galaxy survey is comparable to the ones derived from measurements of the cosmic microwave background.

Also, as was mentioned above, microwave cosmic background radiation has been detected and is considered by many to be the remnant of the primeval fireball postulated by the big - bang cosmological model.
