| « Lyman alpha emission during and after reionization » |
|
Jordi Miralda Escude |
| A powerful probe to the high-redshift universe is found in the detection of Lyman alpha photons produced by several processes: star formation, gas cooling, fluorescence of ionizing radiation, and scattering of the background ultraviolet continuum. I will discuss how Lyman alpha emitting galaxies can be used to study the epoch of reionization at z ~ 6, and other applications of Lyman alpha fluorescence at lower redshifts. |
