The team suggests that light from this gamma-ray burst passed through an unusually dusty part of its galaxy, where a series of supernovas had enriched the surrounding space with dust grains.
The gamma-ray burst, called GRB 060218, lasted almost 2,000 seconds, which is about 100 times as long as a typical burst.
The array was used to perform measurements of asymmetries in neutron capture in gamma-ray emission following capture of [.sup.10]B and [.sup.27]Al.
The entire gamma-ray astronomy community is currently preparing HESS's successor, the Cherenkov Telescope Array (CTA), a planned observatory that will be even more sensitive and based at two sites, one in the northern hemisphere and the other in the southern hemisphere.
"Our measurement complements other search campaigns that used gamma rays to look for dark matter and it confirms that there is little room left for dark matter induced gamma-ray emission in the isotropic gamma-ray background," Mattia Fornasa, an astroparticle physicist at the University of Amsterdam and the lead author of (http://journals.aps.org/prd/abstract/10.1103/PhysRevD.94.123005) a study describing the findings, said in a (http://www.uva.nl/en/news-events/news/uva-news/uva-news/uva-news/content/folder-3/2016/12/fluctuations-in-gamma-ray-background-indicate-two-different-source-classes.html?e=) statement.
Data from the planned Cherenkov Telescope Array, a ground-based gamma-ray observatory, and scheduled upgrades to the DESY ALPS particle-physics experiment in Germany, could reveal if photons do change their stripes.
Tavani's team has used the Italian Space Agency's AGILE spacecraft to monitor gamma-ray emissions from Cygnus X-3 for the past two years.
Based on their observations, LMC P3 was reclassified as a gamma-ray binary.
"One day 3C 279 was just one of many active galaxies we see, and the next day it was the brightest thing in the gamma-ray sky," said Sara Cutini, a Fermi Large Area Telescope scientist at the Italian Space Agency's Science Data Center in Rome.
These exploding stars use all of their energy to emit one last strong beam of highly energetic radiation - known as a gamma-ray burst - before they die.
NASA's Fermi Gamma-ray Space Telescope is watching some of the most extreme phenomena in the distant universe, but little did the Fermi team expect it to be hit from below.
The finding, which has revealed a new class of galactic gamma-ray sources, is not unexpected.
TEHRAN (FNA)- An international team of astronomers, using NASA's Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity of a massive object to bend and amplify light from a more distant source.
