Africa-Press – Sierra-Leone. <\/strong><\/span>While the object examined by the science team seems unique at this time, lead author of the research argued that it may in fact be \u201cthe brightest member of a new population of supernova remnants that emit gamma rays reaching TeV energies.\u201d<\/p>\n

Using the data supplied by NASA\u2019s Fermi Gamma-ray Space Telescope, astronomers have confirmed the remnant of a supernova explosion to be a source of high-energy cosmic ray protons.<\/p>\n

According to a statement released by NASA, said remnant is designated G106.3+2.7 and sits about 2,600 light years away from our planet, in the constellation Cepheus.<\/p>\n

\u201cTheorists think the highest-energy cosmic ray protons in the Milky Way reach a million billion electron volts, or PeV energies,\u201d said Ke Fang, assistant professor of physics at the University of Wisconsin, Madison and lead author of the new study published in Physical Review letters this week. \u201cThe precise nature of their sources, which we call PeVatrons, has been difficult to pin down.\u201d<\/p>\n

The object that attracted the researchers\u2019 attention is a comet-shaped cloud that features a bright pulsar, J2229+6114, on one end \u2013 likely a product of the same supernova explosion that created the cloud.<\/p>\n

\u201cThis object has been a source of considerable interest for a while now, but to crown it as a PeVatron, we have to prove it\u2019s accelerating protons,\u201d said study\u2019s co-author Henrike Fleischhack from the Catholic University of America in Washington and NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland. \u201cThe catch is that electrons accelerated to a few hundred TeV can produce the same emission. Now, with the help of 12 years of Fermi data, we think we\u2019ve made the case that G106.3+2.7 is indeed a PeVatron.\u201d<\/p>\n

Fang also remarked that, while G106.3+2.7 appears unique, it may turn out to be \u201cthe brightest member of a new population of supernova remnants that emit gamma rays reaching TeV energies.\u201d<\/p>\n

\u201cMore of them may be revealed through future observations by Fermi and very-high-energy gamma-ray observatories,\u201d the researcher added.<\/p>\n
