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. Irregular intervals of this radiation (-5[1])are emitted by namesake “soft repeaters.” Neutron star mergers are responsible for “short” events involving this radiation, (15[1])whose “long” (15[1])type is caused by (*) hypernovae. “Bursts” of this radiation are the most luminous events in the universe. This radiation is more energetic than X-rays. For 10 points, name this highest (10[1])frequency form of radiation, whose namesake decay is contrasted with alpha and beta decay. ■END■
