For IPC applicants: If you are interested in applying for the IPC program and require an LCA from the OUTAP group, please ensure to contact the OUTAP faculty members at outap_ipc=at=astro-osaka.jp (replace =at= with @) at least four weeks before the official IPC application deadline.

Research in astrophysics and cosmology is advancing rapidly in both theory and observation, which provides us with an unprecedented view into the nature of the universe.

Our theoretical astrophysics group values two approaches to studying the mysteries of the universe: using the universe as a verification of basic physics, and investigating the evolution of the universe itself based on observational facts. We train new researchers to consider both approaches in order to foster a broad understanding of astronomical phenomena.

We research a wide range of topics, including the following: the formation of galaxies and large-scale structure over cosmic time; high-energy astrophysical phenomena that cannot be replicated on Earth; protoplanetary systems and star formation with accretion disks; extreme compact objects such as neutron stars and black holes; and distortions of spacetime known as gravitational waves.

In all of our research, we place special emphasis on using astronomy to advance our understanding of physics.
