Summary
On the basis of various observations, modern science has developed the Big Bang theory as the standard theory of cosmic evolution, in which the universe was born as a hot dense plasma and became the present universe in the course of its expansion. However, how various astronomical objects were born in the expanding universe has yet to be understood. While we have a rough picture that the universe has evolved through milestone events of the first star and first galaxy formation until the present, what happens in these events is largely unknown.
Computer simulation is a useful tool for investigating the early universe that is hard to observe directly. In this talk, I will first introduce the result of my simulations of the formation of the first stars in the universe. Afterward, I will discuss my current project on simulating the appearance of the first galaxies after the first stars.
