Question

Clover detectors created from high purity germanium crystals are used to detect this radiation. So-called “bubbles” of this radiation were discovered by the Fermi telescope, which studies it. (15[1]-5[1])Irregular intervals of this radiation are emitted by namesake “soft repeaters.” (15[1])Neutron (15[1])star (-5[1])mergers are responsible (15[1])for (15[1])“short” events involving this (15[1])radiation, (15[1]0[1])whose “long” (15[1])type is caused by (*) hypernovae. “Bursts” of this radiation are the most luminous events in the (10[1])universe. This radiation is more energetic than X-rays. For 10 points, name this highest frequency form of radiation, whose namesake decay is contrasted with alpha and beta decay. ■END■ (10[1])
