OC_24_2_7_Naoki_Yoshida_Formation of the First Stars and Black Holes in the Universe

Recent observations using brand-new telescopes such as NASA's James Webb Space Telescope discovered infant galaxies that were in place when the age of the universe was just a few hundred million years. Massive black holes were also found at the early epochs, suggesting mysterious processes that drive star formation in the "cosmic dawn". I review recent progress in the study on the formation of the first generation of stars. I present the results from state-of-the-art computer simulations of cosmic structure formation, and identify several key issues and open questions. Our super-computer simulations start from realistic cosmological initial conditions that incorporate super-sonic gas motions left over from the Big Bang. Tiny magnetic fields generated by the gas motions are also incorporated. I discuss formation of massive stars, black holes, and gravitational wave sources. Finally, I give prospects for future observations using next generation telescopes.
