XRISM Mission Unveils Chemical Secrets of Black Hole in Nearby Galaxy
The Japan-led XRISM project, in collaboration with NASA and ESA, has detected distinctive iron signals in the galaxy NGC 4151, offering new insights into galactic black hole activity.
- XRISM's Resolve instrument captured a detailed X-ray spectrum around the supermassive black hole at the center of NGC 4151, revealing peaks and dips indicative of iron.
- NGC 4151, located 43 million light-years away, exhibits exceptional brightness due to its active galactic nucleus.
- The detected iron emissions and absorptions help astronomers understand the dynamics within the accretion disk and the surrounding torus.
- The findings could provide clues about the growth of supermassive black holes and their interaction with surrounding matter over cosmic time.
- This collaborative mission includes significant contributions from JAXA, NASA, ESA, and the Canadian Space Agency, marking a major step in X-ray astronomy.
