PS1-10adi - an incredibly large explosion 2.4 billion light-years distant

[gary]

In a press release at the University of Belfast (https://www.qub.ac.uk/News/Allnews/Queensastronomerleadsinternationalt eamtoground-breakingfieryexplosioninadistantgal axy.html), it has been announced that
astronomers, using all-sky surveys, have discovered an extremely
energetic explosion, much larger than normal supernova, which they
have designated PS1-10adi.

PS1-10adi had a total radiated energy output of ~2.3 × 10**52 erg.

What's more, they now realize that PS1-10adi is not an isolated case
and that similar transients may have been overlooked in the past.

The discovery has also been reported at phys.org :-

The work is published in Nature Astronomy in a letter entitled "A population of highly energetic transient events in the centres of active galaxies" by Kankare et. al.

Thanks for posting Gary.

Yay, Supernova become sexy again in Astronomy.... time to take the cover off the 12inch...

Hi Peter,

Did you see this thread the other day as well? :-

I was wondering what you, Greg and the BOSS team make of it
given you must be steeped in a lot of science of supernovas by now.

I had never heard of a "Pulsational Pair-Instability Supernovae".

Have you come across this classification before?

Best Regards

Gary
