Abstract

A new class of supernovae In all known supernovae, the radiation they emit comes from internal energy deposited in the outflowing ejecta by one or more processes: radioactive decay of freshly synthesized elements, stored heat deposited by the explosion shock in the envelope of a supergiant star, or interaction between the debris and slowly moving, hydrogen-rich circumstellar material. Quimby et al. report observations of a class of luminous supernovae whose properties cannot be explained by any of these processes. They are about ten times brighter than any type Ia supernova and emit significant ultraviolet flux for extended periods. They can be observed out to redshifts z > 4. These long-lived events, which light up their surroundings, may enable high-resolution spectroscopy to probe distant star-forming regions and primitive galaxies.
