Use "redshifts" in a sentence
"Very deep exposures of a well studied galaxy field has now allowed astronomers to say, with some degree of confidence, just how many more LAGs exist over the whole sky at least for objects with redshifts between 2 and 6."
""By confirming the mass-luminosity relation and extending it to high redshifts, we have taken a small step in the right direction toward using weak lensing as a powerful tool to measure the evolution of structure," says Jean-Paul Kneib a co-author of the ApJ paper from LAM and France's National Center for Scientific Research CNRS."
"It would achieve this by measuring shapes and redshifts of galaxies and clusters of galaxies out to redshifts ~2, or equivalently to a look-back time of 10 billion years."
