Prior to the discovery, the closest astronomers had come to witnessing a supernova's x-ray outburst was in 1987, when researchers saw strongly
ionized gas around a supernova in the Large Magellanic Cloud, which implied that a powerful blast of x-rays had occurred.
The intense radiation from an AGN can
ionize the gas around it (called photoionization), and this may be one mechanism at work in MAMMOTH - 1.

As our solar system slowly orbits
around the galactic center, the sun's ultraviolet radiation carves out an egg - shaped region of
ionized hydrogen atoms surrounded by neutral hydrogen
gas.
If clouds of hydrogen also cluster
around quasars — which convert all nearby neutral hydrogen to invisible
ionized gas — then quasars must have
ionized more hydrogen than astronomers had assumed, Savaglio says.
The main aim of LOFAR is to study the era in the early universe when the very first stars and galaxies were forming and
ionizing all the interstellar
gas around them.
The black holes that we can observe directly through their radiant emission are mostly in a configuration where
gas swirls
around the black hole in the form of an accretion disk and that accretion disk — most of the mass is going to be in an
ionized form, and then some of that
gas gets expelled from the environment
around the black hole, while it is still outside the black hole, it gets squirted out in the form of an outflow, a wind like the solar wind and then [a] much faster, collimated outflow called a jet.
The team used MagAO and VisAO to look for red light from
ionized hydrogen
gas to trace how the strong UV light and wind from Theta 1 Ori C affects the disks
around its neighboring stars.
