The findings could clarify the origins of the enigmatic and brilliant emissions that often come from the deep recesses of space.
A team of researchers believes the flurry of radio waves emanating from deep space came from a bubble of plasma surrounding a compact object, one of the universe’s densest entities.
Astronomers discovered the burst, called FRB20201124A, in 2020, spewing from a source about 1.3 billion light-years away. Last year, a different team of researchers found the, coming from a source about 10 billion light-years away. Thus, the more recently analyzed burst practically seems local. A paper“We were able to demonstrate through observations that the persistent emission observed along with some fast radio bursts behaves as expected from the nebular emission model, i.e.
What kind of dense object could lie at the bubble’s center, you ask? There are a couple of possibilities, but both are very dense. The new data suggests that a magnetar—a strongly magnetized neutron star—may lie at its core. Another possibility is a binary system of a neutron star or a black hole taking voluminous amounts material from a smaller companion star.
