James Webb Telescope Maps Gas Filaments Feeding Supermassive Black Hole in NGC 4696

International astronomers using the James Webb Space Telescope have produced the first detailed observation of how a supermassive black hole draws in surrounding gas. In the central galaxy NGC 4696 of the Centaurus Cluster, about 145 million light‑years from Earth, JWST’s infrared instruments revealed a rotating disk of gas roughly 800 light‑years across, connected to a long filament that streams inward toward the black hole at speeds up to 600 km s⁻¹. The filament acts as a conduit, channeling material that powers the black hole and its energetic jets, while some of the expelled gas later cools and returns to feed the disk again, supporting a self‑regulating cycle of feeding and feedback.

The findings, published in *The Astrophysical Journal Letters*, confirm theoretical models that predict such filament‑disk connections and help explain how supermassive black holes could grow rapidly in the early universe despite the disruptive influence of their own jets. The research involved teams from the Université de Montréal, Michigan State University and NASA, among others, and combines JWST data with earlier Hubble observations and computer simulations.

These results provide a concrete example of the mechanisms that link black‑hole activity to galaxy evolution, showing how gas recycling can sustain black‑hole growth over cosmic time.
