Description
Variable x-ray and γ-ray emission is characteristic of the most
extreme physical processes in the universe. We present multiwavelength
observations of a unique γ-ray-selected transient detected
by the Swift satellite, accompanied by bright emission across the
electromagnetic spectrum, and whose properties are unlike any previously
observed source. We pinpoint the event to the center of a small,
star-forming galaxy at redshift z = 0.3534. Its high-energy emission has
lasted much longer than any γ-ray burst, whereas its peak
luminosity was ˜100 times higher than bright active galactic nuclei.
The association of the outburst with the center of its host galaxy
suggests that this phenomenon has its origin in a rare mechanism
involving the massive black hole in the nucleus of that galaxy.
