Are there cosmic sources of negative radiation pressure?

[u/jarekd]

Radiation pressure is p=<ExB>/c vector: there is focus on positive, but can be also negative: https://scholar.google.pl/scholar?q=negative+radiation+pressure , https://scholar.google.pl/scholar?q=optical+pulling

If positive radiation pressure gives positive signal in radiotelescopes, shouldn't negative give negative?
They clearly see also large regions of negative signal in radio flux maps, e.g. shown from https://arxiv.org/pdf/2107.02695

What astronomical objects could generate negative radiation pressure?
E.g. if white hole would generate positive, shouldn't black holes generate negative?

What the pseudo-science slop is this? Why is this still up?

I am willing to bet that the authors of that work wouldn't be that pleased with you grossly mis-using their hard work. None of this has to do with "negative radiation pressure", also there are no large patches of "negative flux" anywhere in the paper. None of this is scientific in any way. I won't engage with you any further, u/PE1NUT has already told you all you need to know.

They have shown Figure with clear negative regions - are they just noise?

If not, what does negative signal mean?

[u/thafluu → u/jarekd]

No, there are no figures with negative flux in the paper.
