Two Disks in One: How Accretion Disks Drive Black Hole Jets

SMBH jets are driven by thick, hot accretion disks with powerful magnetic fields. But there's a bit of a paradox. Some SMBH produce jets, even though they appear to have thin, cold accretion disks. New research has solved this paradox, showing that disks can be truncated into an outer cold disk and an inner hot disk.
