Welcome

We explore physics behind hot, energetic phenomena in the universe through a wide variety of telescopes including space-based X-ray observatories. Our research particularly focuses on high energy physical processes associated with supernova remnants, neutron stars, and black holes. We also develop new observational instruments for future satellite missions.

私たちは、宇宙X線観測衛星をはじめとする様々な望遠鏡の観測データを用いて、熱く激しい天体現象に潜む物理を突き止めようとしています。特に超新星残骸や中性子星・ブラックホールにおける高エネルギー物理過程を精力的に研究しています。また、将来の衛星搭載を目指して新しい観測機器の開発も進めています。

Paper

The paper by Bamba et al. is now accepted by PASJ.

The paper by Prof. Aya Bamba, “Three-Dimensional Expansion of Iron Ejecta in Cassiopeia A with Chandra and XRISM” is now accepted by PASJ. In this paper, we measured the three-dimentional expansion of a young supernova remnant Cassiopeia A, combining the excellent energy resolution observations by XRISM and excellent spatial resolution observations by Chandra.

Event

We Hosted the International Workshop “Supernova Remnants and Their Friends in the XRISM Era”

As research results on supernova remnants using XRISM are steadily emerging, we hosted the international workshop “Supernova Remnants and Their Friends in the XRISM Era” at the University of Tokyo. The workshop featured presentations on a wide range of topics, including observations of supernova remnants with XRISM and other instruments, models of supernova explosions, and shock-wave physics. Cutting-edge findings were introduced, and participants engaged in lively and fruitful discussions.
