The optical emission has a roughly power-law dependence on wavelength.

Both optical and X-ray emission are heavily absorbed by a giant molecular cloud in the foreground, crossing the whole remnant body from northwest to southeast.

Its overall X-ray luminosity rivals the optical emission and could be that of a nonthermal plasma.

Hence, the optical emission provides astronomers with a detailed "snapshot" of the actual position and geometry of the shock front at any given time.

This was the first discovery of transient optical emission from a short burst.

The optical emissions result from the excitation of atmospheric atoms and molecules by electrons that have been accelerated in the plasma turbulence.

The shell can be clearly seen in optical emission from recombining ionized hydrogen and ionized oxygen atoms.

Because of its 'perylene-type' optical emission in the visible spectrum, it has also been used in organic light emitting diodes.

The optical emission comes from debris further out that is illuminated by these X-rays.

He studies optical and radio emissions from galactic centers and quasars.
