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