While observing a spiral galaxy known as NGC 2082, astronomers have discovered a mysterious, bright and compact radio source. Its origin, to this day, is unknown.
In a study published on its discoverers made several hypotheses about its origin, particularly by comparing it with other signs specified. It will be remembered in particular, with its spectral index and index High often shortened by the FRB acronym for “Fast Radio Blast”. these Mysterious able to release energy in a few thousandths of a second, as much energy as in a day, but their origin remains unknown to this day.
Quasar or radio galaxy
Unfortunately, J054149.24-641813.7 It does not reach a level of luster sufficient to be absorbed in a According to the researchers. Then a few candidates remained in the race: among them the falsies, and some or radio galaxies. But almost all hypotheses have so far been ruled out. Too bright to match A From but ” Not bright enough to be a stable wireless source with a built-in FRB predecessor”this is It has a flat spectral index, i.e. a source that would be of thermal origin.
This spectral indicator also eliminates another possibility: a periodic signal from a that rotates very quickly on itself. There are only two possibilities left: Galaxy Radio. Quasars correspond to the active cores of very bright galaxies, which have in their center a Such as Houses in the middle Arch A*.
Regarding as their name suggests, they are galaxies whose energy emitted from radio waves comes due to . But, whether the source matches one or the other,” We can expect to see some from hello; However, there is currently no Hi High . data for NGC 2082 ”, conclude the researchers. The mystery remains.
