Astronomers have uncovered a critical link between the most massive black holes in the universe and their ability to produce their own fuel. Data from NASA’s Chandra X-ray Observatory and the Very Large Telescope (VLT) has shown that gas ejected by black holes can cool down, forming narrow filaments that feed the black holes again, triggering further outbursts.
This study analyzed seven galaxy clusters, where observations revealed a model where black hole jets heat and cool gas, creating visible filaments. These structures, visible in blue from Chandra data and red from VLT images, showed a consistent relationship: brighter hot gas filaments coincided with brighter warm gas. This finding aligns with observations of jellyfish-like galaxies, suggesting similar processes are at work.
The research predicts that galaxy clusters with brighter hot gas should exhibit correspondingly bright warm gas, supporting the model’s validity. The team achieved this by isolating gas filaments from other structures in Chandra data, revealing previously hidden patterns. This discovery not only deepens our understanding of black hole-gas interactions but also sheds light on star formation and galaxy evolution.
This groundbreaking work was led by Valeria Olivares and published in *Nature Astronomy*. It brings together experts from institutions around the world to advance our knowledge of these cosmic phenomena.
