Accretion Disks & Relativistic Jets: Foundations

Gas approaching a compact object usually carries angular momentum, so it cannot fall straight inward. Accretion physics explains quasars, X-ray binaries, tidal disruption events, jet feedback on galaxies, and some of the universe's most luminous persistent sources.

Gas approaching a compact object usually carries angular momentum, so it cannot fall straight inward.

supported

Viscous and magnetic stresses transport angular momentum outward, allowing matter to spiral inward and release gravitational binding energy.

supported

X-ray binaries show hot inner disks and rapid variability, active galactic nuclei display bright multiwavelength continua and radio jets, and very-long-baseline interferometry resolves relativistic jet motion and structures near supermassive black holes.
