In a groundbreaking discovery, the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) has detected iron signatures in the active galaxy NGC 4151, providing valuable insights into the high-energy processes occurring near black holes and the composition of material in the accretion disk. XRISM, a collaborative mission between JAXA (Japan Aerospace Exploration Agency) and NASA, with contributions from ESA (European Space Agency), has been instrumental in this finding. The mission’s Resolve instrument captured a detailed X-ray spectrum of the vicinity surrounding the black hole at the heart of NGC 4151, revealing distinct peaks and dips akin to chemical fingerprints. These signatures unveiled the presence of iron, which is a crucial element in understanding the dynamics of black holes and their influence on their host galaxies.
