TON 618

TON 618 (abbreviation of Tonantzintla 618) is a hyperluminous, broad-emission-line, radio-loud quasar, and Lyman-alpha blob located near the border of the constellations Canes Venatici and Coma Berenices, with the projected comoving distance of approximately 18.2 billion light-years from Earth. It contains one of the most massive black holes ever found…
