I recently stumbled across this time-lapse telescopic image (radio image, I believe) of the center of the galaxy.



Here's a still image. Link to time-lapse video below.
enter image description here



I haven't been able to find this image anywhere else.

My only source is this obscure YouTube link (timestamp included, to make it easier for you)
https://www.youtube.com/watch?v=Dk2-lH9ewuA&t=143



I don't recall ever seeing this image in the past, and I'm interested to know where it came from.



Is there any publicly-available research around these observations?



The fringe claim is that these images show no evidence of gravitational tidal forces, nor gravitational lensing.

I'd like to read some proper research, explaining what we are supposed to be looking at.

          These are the stellar orbits around Sagittarius A$^*$. The original work and a discussion is available on the Arxiv as the paper Stellar Orbits Near Sagittarius A$^*$ by Eckart, Genzel, Ott and Schoedel. This paper is from 2002 to there have been another seventeen years of observation since. The animation you describe was presumably done using all the recent data. Offhand I don't know where the very latest data can be downloaded. A quick Google failed to locate it but I imagine it's not beyond a more determined search.

            It's infrared optical interferometry with the VLT.



            Have a look at How did they make a video of the center of the galaxy, and what is it exactly that's flashing there? (GIF) and ESOcast 173: First Successful Test of Einstein’s General Relativity Near Supermassive Black Hole (video).
