Research Topic: Fundamental Physics of Neutron Stars Studied via Cosmic X-rays
Teruaki is a high energy astrophysicist studying neutron stars. Neutron stars are compact stellar remnants left after the supernova explosion of massive stars. He is interested in not only an astronomical context of neutron stars but also their extreme physical environment as an ideal laboratory for the fundamental physics because neutron stars exhibit high density, extreme gravity, and strong magnetic field, that can not be tested in ground-based experiments. Among a tremendous diversity of neutron stars, he is especially focus on strange subgroups, Soft Gamma Repeaters (SGRs) and Anomalous X-ray Pulsars (AXPs). They are thought to be strongly magnetized objects (collectively called “magnetars”) and their bright radiation is believed to be powered by huge magnetic energy stored in their stellar interior. Despite accumulated evidence, such a “magnetar” hypothesis is still currently explored. He is challenging to answer this question using next generation X-ray observatories.
