It triggered one of the most powerful explosions in the universe.
GRBs — short duration ones in particular — are exceedingly difficult to capture. According to the scientists, only six have been detected, ever — and even then, only in radio wavelengths.
"Afterglows for short bursts are very difficult to come by, so it was spectacular to catch this event shining so brightly," Fong added.Although capturing short GRBs at millimeter wavelengths may sound like a small distinction to a layman, it’s actually a pretty big deal, the scientists say. "What makes GRB 211106A so special is it’s not only the first short-duration GRB that we detected in this wavelength, but also, thanks to the millimeter and radio detection, we could measure the opening angle of the jet," said study co-author Ruoco Escorial in the statement.
"This is essential to infer the real rates of short GRBs in our universe and to compare them with the rates ofIn other words, using the millimeter data, scientists can begin to calculate just how frequently these kinds of cosmic bursts occur — a fascinating glimpse into some of the most energetic events in the known universe.
