Abstract The James Webb Space Telescope (JWST) has uncovered many compact galaxies at high redshift with broad hydrogen and helium lines, including the enigmatic population of little red dots (LRDs)1,2. The nature of these galaxies is debated and is attributed to supermassive black holes (SMBHs)3,4 or intense star formation5. They exhibit unusual properties for SMBHs, such as black holes that are overmassive for their host galaxies4 and extremely weak X-ray6,7,8,9,10 and radio6,11,12,13 emission.
