reionization

With this, the age of the universe when reionization occurred can then be calculated.

This shows the end of the reionization of the universe.

There are, however, a few observational methods for studying reionization.

The period of universal star birth was the reionization epoch.

YD3) is probably the first galaxy seen in the reionization epoch.

Epoch of Reionization, a process that reionized matter in the universe.

It is unknown, however, how many quasars existed prior to reionization.

The redshifting that occurs allows for temporal information about reionization to be learned.

Quasars also provide some clues as to the end of the Big Bang's reionization.

Some quasars are even detectable as far back as the epoch of reionization.

Other, complementary techniques will allow cosmologists to measure the distribution of matter in the distant universe and to probe reionization.

This includes the very first stars, the epoch of reionization, and the formation of the first galaxies.

The WMAP's detection of an early reionization excluded warm dark matter.

This implies a period of reionization during which some of the material of the universe was broken into hydrogen ions.

LEDA is one of several efforts seeking to study cosmological reionization and the preceding dark ages.

Since an object's redshift corresponds to the time at which it emitted the light we see, it is possible to determine when reionization ended.

The discovery of a galaxy possessing stars that formed only 200 million years after the big bang helps astronomers probe this cosmic reionization epoch.

A population of similar galaxies probably also contributed to this reionization, but they are too faint to see without the magnifying effects of gravitational lensing.

Because of their extreme luminosity in the UV, quasars also are some of the best sources for studying reionization.

This indicates that the intergalactic medium has undergone reionization into plasma, and that neutral gas exists only in small clouds.

Only the brightest of quasars present during reionization can be detected, which means there is no direct information about dimmer quasars that existed.

The October 2010 discovery of UDFy-38135539, the first observed galaxy to have existed during the following reionization epoch, gives us a window into these times.

Reionization shows that dihydroxymethylidene can survive intact, and thus exists as a stable species with appreciable barriers for dissociation or rearrangement to formic acid.

The period of initial active star formation in this galaxy may have lasted less than 100 million years, during which the galaxy likely participated in the reionization event.

In the very distant Universe (), LOFAR can search for the signature produced by the reionization of neutral hydrogen.
