2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/13738We discuss observations of the submm-selected galaxy, SMM J02399-0136, and what has been learnt about it during the year following its discovery. SMM J02399-0136 was the first distant galaxy detected in submm surveys with SCUBA. Its association with a massive, gas-rich starburst/AGN at z=2.8 has lead to suggestions that the prevalence of AGN in the early Universe may be high and that these AGN may account for a significant fraction of the far-IR background.6 pages; to appear in the proceedings of the 1998 Ringberg workshop on ultraluminous galaxiesAstrophysicstext
