Linked from

The 12 pages that link to Lyman-alpha forest, each with the reason it gives.

• RedshiftRelated: The redshifted absorption pattern traces hydrogen gas at different distances along the line of sight.

• Spectral lineBroader topic: Each feature records hydrogen absorption at a different intervening cosmic redshift.

• Cosmic webRelated: Its absorption pattern probes diffuse gas in the high-redshift web.

• QuasarRelated: Quasar light illuminates hydrogen clouds across vast stretches of the early universe.

• Cosmological redshiftRelated: Redshifted absorption features map hydrogen across cosmic distances.

• Intergalactic mediumRelated: Absorption by its diffuse hydrogen makes this the main probe of the medium at high redshift.

• Hydrogen spectral seriesBroader topic: Lyman-series absorption reveals hydrogen gas between distant sources and Earth.

• Stellar mass lossCompared with: Its absorption is not stellar mass loss, but helps distinguish stellar outflows from intervening gas.

• Circumgalactic mediumRelated: Absorption from hydrogen helps distinguish diffuse gas around galaxies from more distant gas.

• Lyman seriesBroader topic: Redshifted Lyman-alpha absorption maps hydrogen gas along distant sightlines.

• Huge-LQGCompared with: Its absorption patterns offer a different tracer of cosmic structure than quasar grouping.

• Lyman-alpha emitterCompared with: Unlike an emitter’s line, the forest consists of absorption imprinted along the sightline.
