The evolution of galaxies from primeval irregulars to present-day ellipticals
arXiv:astro-ph/0512424Publication · DOI
Approach
The simulation tracks the hydrodynamical formation phase and later dynamical relaxation, connecting gas morphology and stellar emission to different observed galaxy classes.
Main result
Early supernova bubbles resemble Lyman-alpha emitters. Around one billion years the stellar continuum resembles Lyman-break galaxies; later relaxation produces an elliptical-like system.
Scientific implications
The model proposes an evolutionary link among populations often observed at different cosmic epochs.
Scope and limitations
This is a demonstrated pathway in a particular simulation, not a claim that all galaxies in these classes follow one universal sequence.
