"A pair of stars spiralling around each other. That’s the origin of a new
source of repeating radio bursts we’ve detected, called ASKAP J1745.
In recent years, astronomers have been puzzling over mysterious bursts of radio
signals, known as long-period transients because of how slowly they repeat.
They were first discovered by chance with telescopes scanning large chunks of
the sky.
To date, astronomers have only found a dozen of these weird sources, and we’re
still trying to understand exactly what they are.
In a new study published today in
Nature Astronomy, we describe a
first-of-its-kind detection – both radio and X-ray bursts repeating with each
orbit.
ASKAP J1745 is exciting because we’ve figured out what it is, unlike 10 of the
12 known long-period transients. Even better, we were able to detect it with a
bunch of different telescopes that observe all different kinds of light.
Bearing the same message in three forms of writing, the famous Rosetta stone
once helped scholars decipher ancient Egyptian hieroglyphs. Similarly, this
extra information we found about ASKAP J1745 will help astronomers better
understand the mystery of all long-period transients."
