" Superluminous supernovae "
Takashi Moriya (NAOJ)
Superluminous supernovae are a newly recognized class of core-collapse supernovae. Their existence is realized only about a decade ago. They are more than 10 times brighter than other core-collapse supernovae. The reasons why they can become very bright are still not understood well. I will discuss the diversity of superluminous supernovae and possible mechanisms to make them superluminous. I will introduce a high-redshift supernova survey recently conducted by Subaru telescope which led to a discovery of a superluminous supernova at z = 2.4. Future infrared transient surveys to detect superluminous supernovae at even higher redshifts will also be discussed.
