Sentences with phrase «alpha spectral line»

Such a break is found in the spectrum of all remote objects (from the crowding of absorption lines creating an effect known as the «Lyman - alpha forest» before the Lyman - alpha spectral line at rest wavelength 121.6 nm).

The object studied here has a redshift of z = 5.913, i.e., the Lyman - alpha spectral line of hydrogen at 1216 angstrom (Å) at the rest frame is detected at 8406 Å, when the Universe was about one billion years old.

Not exact matches

Led by Canadian researchers under what's called the ALPHA Collaboration, the first detailed observation of «home made» anti-hydrogen's structure has shown its spectral lines are virtually identical to those of hydrogen.

Indeed, its Lyman - alpha spectrum, i.e. one of the spectral lines of hydrogen it emits, is much narrower and stronger than that of most galaxies, therefore confirming her theoretical predictions.

When hydrogen gas is heated by the ultraviolet emissions of new stars, it produces a spectral signature called the Lyman - alpha line.
