Sagittarius A* in Radio
Recently astronomers using an array of radio telescopes around the world created an image of the M87 core in a band of radio spectrum.
Here is an interesting video in radio of the Milky Way core, from a 2017 news story.
Perhaps others will find this linked content entertaining.
They call it a 'nonthermal radio filament' (NTF) or a 'cosmic string' but a person involved in the study said this:
"However, we still have more work to do to find out what the true nature of this filament is."
This story has a link to a paper titled:
A Nonthermal Radio Filament Connected to the Galactic Black Hole?
The ? in the title confirms their lack of understanding for the observation.
That reference has this:
Many of the NTFs show filamentary substructure—a doubling of the filamentary strands, or even in some cases a tightly packed bundle of parallel filaments.
This description sounds like they imaged a pair of birkelund filaments at the Milky Way core.
The story and the paper have fantasy references to a black hole (Sag A*) and cosmic strings.
This discovery is potentially 'awesome' with these two remarks:
stunning high-resolution images that might finally offer researchers some tangible clues for figuring out if this string acts as a bridge to another universe.
If the third theory turns out to be true, this cosmic string would have profound implications on our understanding of gravity, space-time and what lies beyond our known universe.
With those possible consequences I am surprised this never made my news sources. :-)
