Little Red Dots can contribute ~30% of the diffuse neutrino background at TeV-sub-PeV energies through photomeson production in black hole envelopes, with modified flavor ratios at higher energies.
Four dual LRD candidates at z~5.5 with kpc separations show 20-30x excess sub-arcsec clustering versus extrapolated AGN ACF, implying merger-driven SMBH growth.
The Sparks survey divides local galaxies into first-burst, second-burst, and post-burst groups, finding AGN predominantly in second-burst systems and implying a short delay before black hole accretion.
Super-Eddington accretion boosts predicted LISA detections of high-redshift black hole binaries to ~64 per year while dropping ET detections to ~4 per year, compared to ~32 and ~64 under Eddington-limited growth.
High-redshift AGN emitting UHE protons up to 10^19 eV generate a 50 PeV cosmogenic neutrino bump consistent with IceCube data from their JWST-measured average properties without fine-tuning.
