Researchers reported evidence that the black holes at the centre of most galaxies help regulate the pace of star formation in their host systems. The findings appear in a 2026 paper by Roy, Borthakur, Heckman and Singh in Astrophysical Journal Letters. An artist’s illustration, credited to Hailey Nelson of Arizona State University, depicts a supermassive black hole spewing pink plasma jets that could suppress star formation. The study confirms the long‑expected effect of such jets on the surrounding gas cloud.
Context
Supermassive black hole jets heat and push away the gas that would otherwise collapse to form stars, a key process in how galaxies evolve over billions of years.
ExplainerWhy this matters
What Happened
A 2026 study reported that plasma jets emitted by super‑massive black holes interact with the surrounding gas halo of their host galaxies.
Why It Matters
When these jets heat or push away the gas, the material can no longer collapse to make new stars, which slows the growth of the galaxy and shapes its long‑term evolution.
What Happens Next
The authors note that further observations of other galaxies will be needed to see how widespread this halo‑effect is and to refine models of galaxy formation.
