The X-Ray Imaging and Spectroscopy Mission (XRISM), launched on September 7th, 2023, is a collaborative mission between JAXA and NASA, with contributions from over 70 institutions in Japan, the U.S., Canada, and Europe. With the successful combination of high-resolution spectroscopy and wide-field imaging, XRISM has provided us with an unprecedented view of the Universe, opening a new era of high-energy astronomy.

This conference will highlight the scientific achievements from the first two years of XRISM and identify key issues we should address in the next observation cycles. Conference topics also cover theoretical studies related to XRISM observations and synergies with other observatories, including future missions.

Topics

• Formation of the largest structure in the Universe
• Chemical evolution of the Universe
• Active galactic nuclei and their environment
• Endpoint of stellar evolution
• Accretion and outflow in compact objects
• New physics with high-resolution X-ray spectroscopy
• XRISM for multi-wavelength/multi-messenger astronomy
