Chemodynamics of Lyman alpha emitters, Lyman break galaxies and elliptical galaxies
We report an ultra-high-resolution simulation that follows evolution from the
earliest stages of galaxy formation through the period of dynamical relaxation.
The bubble structures of gas revealed in our simulation (
years) resemble closely the high-redshift Lyman emitters (LAEs). After
years these bodies are dominated by stellar continuum radiation and look
like the Lyman break galaxies (LBGs) known as the high-redshift star-forming
galaxies at which point the abundance of elements appears to be solar. After
years, these galaxies resemble present-day ellipticals. The
comparisons of simulation results with the observations of elliptical galaxies
allow us to conclude that LAEs and LBGs are infants of elliptical galaxies or
bulge systems in the nearby universe.Comment: To appear in the proceedings of the CRAL-Conference Series I
