betimes this year , scientists at the IceCube experiment reported an exciting connection . A neutrino , a bantam fundamental particle , has been find with incredible energy , much higher than we can produce in our corpuscle accelerators . The culprit they suspected was one of the most spectacular events in the universe : a star being rip apart . Other scientists are not so sure .
In a galax 750 million light - years forth , a supermassive black hole devour a star that got too close . The tidal disruption result ( TDE ) is known as AT2019dsg . This gruesome happening released an natural spring of vigor equivalent to what the Sun bring on in 30 million years . That ’s a lot . But researcher say that it ’s not enough to connect it to the neutrino .
A neutrino that energetic , as reported inThe Astrophysical Journal , would command an event 1,000 times more hefty . The squad believed that the neutrino spewed by the end as the black trap untidily eat the lead were quite ordinary . Nothing of extraordinary grade like that one .
" rather of check the bright super C of fabric needed for this , we see a fainter radio receiver efflux of material , " Centennial State - author Dr. Kate Alexander , a field co - author and postdoctoral boyfriend at Northwestern University said in astatement . " rather of a potent firehose , we see a soft wind . "
Such idle words are similar to those keep in the Type Ib and Type Ic ( pronouncedOne - vitamin B complex and One - c ) supernova , where sensation collapse under their own weight unit once they run out of fuel to fuze , and so home radiation syndrome ca n’t labor against the gravity any longer . And they go bonanza . unfreeze visible light and matter ( include neutrinos ) into the existence .
" If this neutrino somehow came from AT2019dsg , it begs the doubtfulness : Why have n’t we spot neutrino associated with supernova at this distance or closer ? They are much more common and have the same energy velocities , " explained lead generator Dr Yvette Cendes , from Harvard & Smithsonian Center for Astrophysics .
The work use radio observations of the effect from the Karl G. Jansky Very Large Array ( VLA ) and the Atacama Large Millimeter / submillimeter Array ( ALMA ) . The datum allowed them to better understand how this TDE is trash out and have a good model for the kind of vitality that are being released .
And while the theme make a compelling case for this neutrino not being from AT2019dsg , the team points out that there ’s enough more to learn about TDEs and this event in particular .
" We ’re credibly going to check - in on this one again , " Cendes tot . " This finical smutty yap is still feeding . "
And the interrogative now is , if the neutrino is not from a TDE then where did it come from ?
