SN 2006gy was an extremely energetic supernova, also referred to as a hypernova, that was discovered on September 18, 2006. It was first observed by Robert...

supernova yet recorded, twice as bright as the previous record holder, SN 2006gy, though SN 2005ap was eventually surpassed by ASASSN-15lh. It was initially...

that SN 2006gy is a likely candidate for a pair-instability supernova. SN 2005ap, which was discovered by Robert Quimby who also discovered SN 2006gy, was...

bright as the previous record holder, SN 2006gy. Although SN 2005ap was twice as bright at its peak than SN 2006gy it was not as energetic overall as the...

supernova similar to the SN 2007bi event. It also had some similarities to the low redshift SN 2006gy supernova. Overall classification of SN 1000+0216 remains...

pair-instability supernovae include: SN 2006gy SN 2007bi, SN 2213-1745 SN 1000+0216, SN 2010mb OGLE14-073, SN 2016aps SN 2016iet, SN 2018ibb, Pair production Pulsational...

(23.5 million pc) from Earth. It was the host galaxy of the supernova SN 2006gy, one of the brightest ever recorded. It is a member of the Perseus Cluster...

through modern astronomical telescopes. The most recent naked-eye supernova was SN 1987A, which was the explosion of a blue supergiant star in the Large Magellanic...

quark-novae is scant; however, recent observations of supernovae SN 2006gy, SN 2005gj and SN 2005ap may point to their existence. QCD matter, also known as...
