Because a gamma-ray spectrum reveals how much of this high-energy radiation is absorbed, it provides a tally of the lower-energy photons generated by all the galaxies that lie between the distant blazar and Earth, says Romani.

Furthermore, because the gamma-rays should be coming from a narrow shell of gas, the range of wavelengths would be small, producing a sharp line in the gamma-ray spectrum.

The distinctive signature of a superdeformed state is a strikingly regular gamma-ray spectrum -- the nucleus sequentially casts off 19 gamma rays, each of which carries two units of spin, thereby slowing down the dysprosium rotation step by step from 60 * to about 22 *.
