from fallback to a black hole, but type IIn slsne have significantly different light curves and are not associated with gamma-ray bursts. M.; Gal-Yam,.; Arcavi,.; Sullivan,.; Nugent,.; Thomas,.; Howell,. Type IIn supernovae are all embedded in a dense nebula probably expelled from the progenitor star itself, and this circumstellar material (CSM) is thought to be the cause of the extra luminosity. Some theories propose these will produce either Type Ib or Type Ic supernovae, but none of these events so far has been observed in nature. The next step in their research will be to apply simulations on other slsne, and make more realistic models by considering the asymmetry of the explosion and physics of the magnetar-powered supernova. Reviews of Modern Physics. Smith,.; Chornock,.; Silverman,. In particular, for asassn-15lh, they were able to find a magnetar source with physically allowed properties of magnetic field strength and rotation period.

The second, asassn-15lh, was discovered in 2015 and is possibly the most luminous and powerful explosion ever seen, more than 500 times brighter than normal supernovae. In the future, their technique could help researchers in identifying the explosion mechanism of supernova they observe.

They analyzed two recently discovered super-luminous supernovae: SN 2011kl and asassn-15lh. But the energy source of their super-luminosity, and explosion mechanisms are a mystery and remain controversial amongst scientists. 5 PS1-11ap is similar to a type Ic slsn but has an unusually slow rise and decline. Although originally expected to produce slsn explosions hundreds of times greater than a supernova, current models predict that they actually produce luminosities ranging from about the same as a normal core collapse supernova to perhaps 50 times brighter, although remaining bright for much longer. G.; Fouchez,.;. First, SN 2011kl was discovered in 2011 and is the first supernovae to have an ultra long gamma-ray burst that lasted several hours, whereas typical long-duration gamma-ray bursts fade in a matter of minutes.
A b McCrum,.; Smartt,. Not only did they discover that Gaia16apd was most likely a shock-interacting supernova, Tolstov and his team found a way to model three different scenarios at UV wavelengths using the same numerical technique.
