However, this emission has not been detected [20, 47]. The broad Balmer emission lines observed in the JWST data imply a clumpy gas structure (e.g. Refs. [48, 49]), contradicting the hypothesis of a completely closed, cocoon-like envi- ronment. Alternatively, the more frequently found faint broad-line AGN population, other than LRDs, may also be capable of accelerating protons to 10 EeV.
