Star/Galaxy formation
in the early universe

My research focuses on formation theory of the first-generation stars/galaxies in the early universe by performingnumerical simulattions.

Research Topics

Formation process of the first-genertaion objects in the early universe

Cosmological simulation

Ab initio cosmological simulation

From cosmological to protostellar scale

Density distribution of dark matter halos

Statistical approach

Various formation pathes result in initial mass distribution

Fragmentation of protostellar disc

Stellar masses

By considering both cloud collapse and protostellar accretion phases

Distribution of Pop III.1(yellow) and III.2(red) stars.

Overall perspective

Influences on subsequent events
