Black hole-powered central engines producing bright emission at various wavelengths and jets extending far beyond the galaxy are common to many galaxies but show different properties when observed.

This central accreting region of AGNs has hitherto been spatially unresolved and its structure therefore unknown. This disk called an accretion disk heats up due to the gravitational and frictional forces at work.
