To study the formation of the first galaxies, it is important to understand the formation of Population III stars, since these massive stars affect the formation of the next generation stars with strong radiative feedback and supernova explosion. However, it is difficult to study them because their formation covers various physical scales from cosmology to the size of a single star. To overcome the limitation of numerical simulation, we are developing a new method and study the formation of the first stars in various conditions.
Since the first stars are thought to be very massive, their impact on their environment should be significant. We are studying the relation between Population III stars and galaxies in the universe.
I studied the formation of star clusters using high-resolution cosmological simulation.
I made galaxies in numerical simulations look like real galaxies seen through telescopes. For this purpose, I make use of Monte Carlo radiative transfer code SKIRT (SKIRT homepage).
