The little red galaxies that may be sending us neutrinos

Caption

At the center of the Little Red Dot, there may be a black hole surrounded by a thick outer gaseous envelope. In this environment, photons produced near the center are absorbed and scattered by the gas, so neutrinos can escape the envelope without interacting with the surrounding gases. If there are many Little Red Dots, they may account for a part of the high-energy neutrinos arriving from the universe.
