Summary

Story summary

The XRISM satellite shows small black holes consume matter more chaotically, altering galaxy understanding.
Jon Miller from the University of Michigan leads the international team, publishing in The Astrophysical Journal Letters.
Launched in September 2023, XRISM is ten times more sensitive than prior X-ray instruments.
The study examined the X-ray binary system 4U 1630-472, revealing gas ejections at 3% of light speed.
Future XRISM funding is uncertain amid budget requests that could eliminate U.S. support.

History

Historical Context

The Chandra X-ray Observatory, launched in 1999 with a budget of $1.5 billion, advanced our understanding of black holes and cosmic phenomena. Following the loss of the Hitomi satellite in 2016, the XRISM mission, launched on September 6, 2023, aims to recover and expand upon these insights, addressing funding challenges that have historically impacted NASA's astronomical research.
