New research shows that plasma jets launched by supermassive black holes travel into the circumgalactic medium. This energy injection prevents the gas from cooling and collapsing, ultimately halting star formation.

Why it matters

Understanding how these jets influence gas dynamics is essential to explaining how galaxies stop growing. By heating the surrounding medium, black holes actively regulate the star-forming potential of their host galaxies.

Researchers utilized data from the DESI and LoTSS surveys to map the energy distribution of plasma jets. These jets blast energy from galactic centers into the circumgalactic medium to heat necessary star-forming gas.

The players

DESI

The Dark Energy Spectroscopic Instrument is a specialized survey project designed to map the expansion history of the universe and cosmic structure.

LoTSS

The LOFAR Two-metre Sky Survey is an international astronomical survey that maps the radio sky at low frequencies to study galaxies and black holes.

The details

Supermassive black holes at the center of galaxies generate powerful plasma jets that distribute immense heat energy far beyond the galaxy's core. This thermal output interferes with the cooling process required for gas to condense and form new stars.

The Big Picture

This research follows a pattern set by the M87* black hole jet observations by providing empirical evidence of how central black holes impact their host environments. It fundamentally updates the understanding of galactic evolution by demonstrating the active role of black hole feedback.

While this discovery concerns celestial processes, it refines the models scientists use to predict the life cycle of galaxies across the universe. This knowledge helps researchers better understand the long-term structural development of the cosmos.

The takeaway

Galaxies rely on a delicate thermal balance to sustain the creation of new star systems. When supermassive black holes introduce high-energy plasma, they effectively shut down this process by keeping surrounding gases too hot to collapse.
