Galaxy Evolution Can be Affected by Black Hole Jets
Astronomers have discovered that supermassive black hole jets significantly influence galaxy evolution by heating surrounding gas reservoirs. This process can either inhibit or promote star formation depending on the energy released into the circumgalactic medium.
Why it matters
Understanding the feedback loop between black holes and their host galaxies is fundamental to mapping the history and structure of the universe.
In recent decades, astronomers have found evidence that supermassive black holes can really mess with their galaxies' evolution. They gobble up material intended for star formation, quenching the birth of stars. Conversely, jets streaming away from those hungry monsters can energize gas-rich regions and enhance the chances of a galaxy birthing batches of stars in those areas.
