Strange, repeating radio signal near the center of the Milky Way has scientists stumped | Live Science
In the observations near the center of the Milky Way galaxy conducted by ASKAP from April 2019 to August 2020, 'strong radio waves emitted over several weeks' were observed 13 times in total from a specific position. The observation team named this radio wave ' ASKAP J173608.2-321635 ' and verified its identity.
Through past space observations, celestial bodies called 'pulsars ' that emit strong radio waves and X-rays on a regular basis have been discovered. However, 'ASKAP J173608.2-321635' does not apply to pulsars because it emits radio waves at irregular intervals and does not emit X-rays.
In addition, there are celestial bodies called 'magnetars ' that have a strong magnetic field as celestial bodies that emit radio waves. However, since magnetars emit very strong X-rays when emitting radio waves, 'ASKAP J173608.2-321635' does not apply to magnetars either.
From the above, the observation team thinks that 'ASKAP J173608.2-321635' is one of the 'galactic center radio transients (GCRT)' that emits irregular radio waves in the galaxy. According to the observation team, only three GCRTs have been discovered by the time the article was created, and it is known that all of them emit radio waves shorter than 'ASKAP J173608.2-321635'. For this reason, the observation team is looking forward to new discoveries, stating that 'ASKAP J173608.2-321635 may bring new insights into GCRT.'
In ASKAP, which discovered 'ASKAP J173608.2-321635' this time, a mysterious object that experts have told in the past that 'it cannot be explained by the current theory' has been found.
What is an unidentified 'ORC' floating in the universe where experts are excited that 'the current theory cannot explain it'? --GIGAZINE
