I think it’s impossible to sync or phase thousands of antennas at different locations from the surface of an accelerating sphere. Call me cynical. I am, but technically is what I mean.

Making the composite creamy with puffy trails and a crosshatching background.

I find it difficult to discern a laser beam like linear flare. Maybe it’s my eyes again.

Which is moving faster, the puffs or the puffers? Looks intermittent to me. With quite a time span.

BH cycling? Does ours cycle? Our bubbles might be remnants of it. It might have started flaring and we not know it yet.

Would love to see the raw image from those the other sources. Artists seem to have a lot of liberty.

Or imagination. I do admit a bias for these “artist impressions”.
 
What does it all mean?
Scientists continue to research to understand the properties of compact matter.

Pi in the Sky: Neutron Stars with Exceptionally Light QCD Axions​

Mia Kumamoto, Junwu Huang, Christian Drischler, Masha Baryakhtar, Sanjay Reddy

we present a comprehensive study of axion condensed neutron stars that arise in models of an exceptionally light axion that couples to quantum chromodynamics (QCD). These axions solve the strong-charge-parity (CP) problem, but have a mass-squared lighter than that due to QCD by a factor of ε<1. Inside dense matter, the axion potential is altered, and much of the matter in neutron stars resides in the axion condensed phase where the strong-CP parameter θ=π and CP remains a good symmetry. In these regions, masses and interactions of nuclei are modified, in turn changing the equation of state (EOS), structure and phenomenology of the neutron stars. We take first steps toward the study of the EOS of neutron star matter at θ=π within chiral effective field theory and use relativistic mean field theory to deduce the resulting changes to nuclear matter and the neutron star low-density EOS. We derive constraints on the exceptionally light axion parameter space based on observations of the thermal relaxation of accreting neutron stars, isolated neutron star cooling, and pulsar glitches, excluding the region up to 5×10−7≲ε≲0.2 for ma≳2×10−9eV. We comment on potential changes to the neutron star mass-radius relationship, and discuss the possibility of novel, nuclear-density compact objects with θ=π that are stabilized not by gravity but by the axion potential.
 
What does it all mean?
Axions may be real even if not yet detected (they are theoretically extremely weak in interaction with ordinary matter) and are considered a dark matter contender. In trying to answer it seems they are needed (?) as part of 'standard theory'.

It seems to be a way in which the presence of axions in neutron stars could constitute a validation of standard theory by showing how things may work. But if you really are interested you better check this out I do not want to mislead.
