The First Billion Years of the Universe - Rising Galaxies

Ken Chen

One of the paramount problems in modern astrophysics is to understand the end of the cosmic dark ages when the first stars and galaxies transformed the simple early universe into a state of ever-increasing complexity. Modern cosmological simulations suggest that the hierarchical assembly of dark matter halos provided the gravitational wells that allowed the primordial gases to form stars and galaxies inside them. The first galaxies comprised of the first systems of stars gravitationally bound in dark matter halos are naturally recognized as the building blocks of early Universe. In this talk, I will discuss the physical mechanics behind the first galaxy formation and present the predictions of their observational signatures which will be examined by the future observatories such as JWST and TMT.
