JWST finds AGN feedback slowly starved 'Pablo's Galaxy', supporting gradual quenching

JWST observations show the central black hole in 'Pablo's Galaxy' slowly starved the system, supporting a model of gradual AGN-driven quenching rather than abrupt shutdown. The finding points to long-term starvation of star formation rather than a single violent 'death blow' to the galaxy's growth.

Briefing

What Hype is tracking

  • Shows active galactic nucleus (AGN) feedback can suppress star formation through prolonged "starvation," a distinct pathway from rapid, violent quenching and an important constraint for galaxy-evolution models.
  • Reinforces JWST's role in revealing detailed AGN–host interactions and mature galaxy structure at earlier epochs, adding context to the telescope's prior discoveries of unexpectedly developed galaxies (see source:685277e6-71df-418a-aa40-652dbe702aec).
