New Look at Messier 82 Reveals Superwind Source, Young Star Clusters
With the new Subaru image, scientists have gained insight about the sources of the superwind.
“The wind is found to originate from multiple ejection sites spread over hundreds of light years rather than emanating from any single cluster of new stars. We can now distinguish ‘pillars’ of fast gas, and even a structure resembling the surface of a ‘bubble’ about 450 light years wide,” Gandhi explained.
COMICS has detectors particularly adept at indicating the presence of warm dust, which it found was more than 100 degrees hotter than the bulk of material filling the rest of the galaxy. The widespread, continuous flow of energy from young stars into the galactic expanse keeps the dust hot.
In a paper published today in the Nature Photonics journal, Swinburne researchers Dr Baohua Jia, Dr Xiangping Li and Professor Min Gu and their collaborators from Shanghai, have demonstrated the reversal of this effect, which does not occur naturally. That is, when an object and a light wave detector moved closer together, they were able to decrease the light frequency from blue wavelengths to red ones, and vice versa.
“This is the first time in the world that the inverse Doppler Effect has been demonstrated in the optical region,” Professor Min Gu, Director of Swinburne’s Centre for Micro-Photonics said.
The researchers were able to achieve this by creating an artificial nanostructured crystal – known as a ‘photonic crystal’ – out of silicon.
By projecting a laser beam onto the unique photonic crystal ‘super prism’ and changing the distance between it and the detector, the researchers were able to create an inverse Doppler Effect phenomenon.
“In our super prism the dispersion of light was twice the magnitude of a standard Newton Prism. This large angle makes the prism’s refractive index – a property that determines how fast light travels through it – change to negative,” Professor Gu said.
According to the article, it "does not occur naturally" so you won't see it in nature according to that.

so if experimenally we can now produce blueshift from recessional velocity using a "super prism"
what would happen if our helo-galaxy lenset had a similar effect on objects under observence?
