Recombination

Recombination often refers to the process of mixing up parental DNA to produce offspring with genes from both parents. I suspect that it could refer to any iterative combinatorial process. ?

Recombination may refer to:* Genetic recombination, the process by which genetic material is broken and joined to other genetic material* Carrier generation and recombination, ...

Recombination lines (especially Ha): Line emission is characteristic of H II regions, zones of ionized gas around young star clusters that still contain OB stars (spectral types B0.5 and hotter).

Recombination (a) The capture of an electron by a positive ion. It is the inverse process to ionization.

recombination - (n.) The addition of an electron to an ion, usually resulting in radiation (recombination lines) when the electron subsequently jumps down to lower energy states. recurrent nova - (n.) ...

Recombination The stage within 1 million years of the big bang when the gas became transparent to radiation Recurrent Nova ...

Recombination Epoch - The time, about 1 million years after the expansion of the universe began, when most of the ions and electrons in the universe combined to form atoms ...

The Recombination Era was a time in which ... 1: ... electrons first combined in large numbers with protons to form atoms. 2: ... the first helium nuclei were formed. 3: ... light elements combined to form heavy elements. 4: ...

Shortly after recombination, baryonic matter begins to condense around cold dark matter halos. Zero-metal high-velocity halo stars (called Population III stars) are the first to develop around a protogalaxy as it starts to contract.

At the time of recombination, the number of unit particles was cut at least in half (one electron + one proton become a single atom; the neutrons also were incorporated into the atoms).

from the sun is essentially monochromatic, that the ionized constituent is distributed exponentially (with a constant scale height), and that there is an equilibrium condition between the creation of free electrons and their loss by recombination.

This happened at what is called the recombination era of the thermal history of the Universe.

In trying to learn even more about the universe, I've picked up several books but am stuck on the theory of recombination and how it relates to transparency.

Recombination of electrons and protons, plus collisional excitation of other atoms by energetic free electrons, then produces the nebular radiation, which consists almost entirely of emission lines.

In the upper stratospheric regions, absorption of ultraviolet light from the Sun breaks down oxygen molecules; recombination of oxygen atoms with O molecules into ozone (O ) creates the ozone layer, ...

If the dark matter is composed of abundant light particles which remain relativistic until shortly before recombination, then it may be termed "hot". The best candidate for hot dark matter is a neutrino [..] ...

observed from clouds of ionized hydrogen (termed H II regions) located along the spiral arms of the Galaxy. When free electrons recombine with ions of hydrogen or other light elements, radio energy is released that can be observed as recombination ...

This type of nebula is created when energetic ultraviolet light from a hot star shines on a cloud of hydrogen gas, stripping away electrons from the atoms (ionization). The free electrons can then begin the process of recombination.
