During observations of a spiral galaxy called NGC 2082, astronomers discovered a mysterious, bright, and small radio source. Its origin is unknown to this day.
In a study published on Its inventors have developed many hypotheses about its origin, especially by comparing it to other signals. Was identified. It is particularly reminiscent of its spectral index and thereby High, The Often abbreviated as FRB “Fast radio blast”. These are Mysterious ones emit a few thousandths of a second of energy In a day, but their origin has not been identified to this day.
A quasar or a radio galaxy
Unexpectedly, J054149.24-641813.7 did not reach a sufficient luminosity level to integrate into a , According to researchers. Some candidates are in the race: some of them are Quasars, And some Or radio galaxies. But almost all hypotheses have so far been rejected. Bright enough to match Of But ” Not bright enough to be a source – standard radio with a built – in FRB progenitor. “This Has a flat spectral index, i.e. a source with a thermal origin.
This spectral code eliminates another possibility: The a periodic signal from a Will change itself very quickly. There are only two more possibilities: And radio galaxy. Quasars are similar to the active nuclei of very bright galaxies in that they have a center As well Houses in its center Sagittarius A *.
As As their name implies, they are galaxies whose energy comes from radio waves . But even if the source matches one or the other, ” Expect to see some Hi from; However, there is currently no Hi High data To NGC 2082 “, The researchers conclude. The mystery still lingers.
