Key Points

  • The study aims to explain the growth of supermassive black holes and the rapid quenching of galaxies using a new framework.
  • Utilized recent JWST observations to identify compact infrared sources and galaxy behaviors.
  • Developed the Cocooned Accretion + Anisotropic Feedback (CAAF) framework.
  • Derived conditions based on conservation laws and radiative transfer principles.
  • Identified a population of compact infrared sources potentially linked to black holes.
  • Observed rapid quenching effects in galaxies during episodic feedback.
  • Predicted key astronomical metrics like line ratios and continuum slopes associated with infrared luminosity.

Abstract

AbstractRecent JWST observations have uncovered:1. A population of compact infrared sources at high redshift, potentially accreting black holeswithin dense ionized gas.2. Galaxies experiencing rapid quenching through episodic feedback.3. Accelerated chemical enrichment in early galaxies.We propose the Cocooned Accretion + Anisotropic Feedback (CAAF) framework. This modelelucidates how early supermassive black hole (SMBH) growth occurs within an optically thickcocoon, explaining energy conversion into infrared spectra, suppression of typical AGN signa-tures in X-ray and radio, and directional outflows guided by geometry. We derive conditionsbased on conservation laws and radiative transfer. Our predictions include line ratios, contin-uum slopes, variability, polarization, and potential scaling relations between compact infraredluminosity and quenching indicators.
