Description
Supermassive black holes with masses of millions to billions of solar
masses are commonly found in the centers of galaxies. Astronomers seek
to image jet formation using radio interferometry but still suffer from
insufficient angular resolution. An alternative method to resolve small
structures is to measure the time variability of their emission. Here we
report on gamma-ray observations of the radio galaxy IC 310 obtained
with the MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov)
telescopes, revealing variability with doubling time scales faster than
4.8 min. Causality constrains the size of the emission region to be
smaller than 20% of the gravitational radius of its central black hole.
We suggest that the emission is associated with pulsar-like particle
acceleration by the electric field across a magnetospheric gap at the
base of the radio jet.
