Scientists have discovered something strange that originated in the center of the Milky Way galaxy: a signal previously overlooked that they think originates from the supermassive black hole in the center of our galaxy.
The team of researchers at Keio University thinks the signal is caused when the accretion disk around the black hole explodes and gives off super-fast rotating radio areas, according to research published last month on The Letters of the Astrophysical Journal – providing a glimpse of the unimaginable chaos at the core of our galaxy.
Flickering signals are not completely new – scientists have previously discovered larger and slower flares. But thanks to the Atacama Large Millimeter / submillimeter Array (ALMA), scientists are now seeing more minutes appear than ever before.
“At this time, using ALMA, we were able to obtain Sgr A * high-frequency radio-wave power variation data for 10 days, 70 minutes per day,” said the lead Yuhei Iwata is set. “Then we found two trends: quasi-seasonal variations with an average time scale of 30 minutes and hour-long slow variations.”
“This release may be related to some of the peculiar phenomena that occur in the super surroundings of the supermassive black hole,” Keio University professor Tomoharu Oka said in a press release.
The fluctuation is likely to be caused by the dizzying gas rotation around the black hole – which helps explain why it’s so difficult to directly follow.
“Generally, the faster the motion is, the harder it is to take a picture of the object,” Oka said.
