Satellite Galaxies All in a Row—How So?

… snip …

Large galaxies like our Milky Way are surrounded by swarms of smaller satellite galaxies. In simulations of galaxy formation made using the standard model of cosmology, the Lambda Cold Dark Matter model (ΛCDM), these satellite galaxies end up orbiting mostly randomly. That is to say, you generally wouldn’t expect to find multiple satellite galaxies having orbits similar to each other and orbiting in the same direction. However, observations of the Milky Way, the Andromeda Galaxy (M31), and the relatively nearby galaxy Centaurus A have revealed the presence of large, coherent planes of satellite galaxies orbiting around all three. And not only are many of the satellites orbiting in a plane, but in each case the majority of the galaxies in the plane are also orbiting in the same direction. (See Figure 2 for an overview of the various planar structures around the three galaxies.)

The Problem: Comparison to Simulations

The interesting part of all this is that in the best simulations we have right now such tightly correlated satellite galaxy planes are extremely rare. To measure just how rare Pawlowski searched two large simulations, the Exploring the Local Volume in Simulations (ELVIS) suite and Millennium-II, for galaxies comparable to the Milky Way, M31, and Centaurus A. He then looked at their satellite galaxies to see how they compared to what we observe in nature.

The result? Planes of satellite galaxies turned out to be extremely unlikely, showing up in a mere 0.1% (Millennium-II) to 0.5% (ELVIS) of galaxies. This might not be a problem if we only knew of one such structure, but we now know of three in the local universe which is significantly more than we’d expect to find based on these simulations. This discrepancy is known as the Planes of Satellite Galaxies Problem, and has been suspected for a number of years now (see for instance this earlier Astrobite).
And as the article explains, none of the explanations the mainstream has come up with solve the problem.
So there we have it: dwarf satellite galaxies are too orderly. Pawlowski concludes that at this point it remains an open question how these planes of satellite galaxies are formed.
Wonder if the authors are aware of EU and the work of Arp?

Apparently not yet …

Here’s the DM community’s latest solution to the plane of satellites problem …

https://arxiv.org/abs/2205.00712

A Fifth Force and a new particle … the “symmetron” … that can generate invisible walls in space.

All to keep the notion of Dark Matter alive.

I kid you not.

And, of course, there’s no mention of EU theory, filaments or electric currents in the paper, or that they even considered EU when looking at alternatives to what they proposed. As Stephen Smith says (https://www.thunderbolts.info/wp/2011/1 ... umbilicus/ ) EU posits
that currents of electric charge flow through a galaxy along its polar axis and then out through the spiral arms. A circuit across the galactic disk divides into upward and downward currents that flow back into the poles. This circuit is driven by Birkeland currents that connect the galaxy with the rest of the Universe. Presumably, billion-light-year long magnetically confined electric filaments transmit power from one end of space to the other.

Birkeland currents move through the center of the Milky Way, where they may generate a cylindrical particle beam effect at the edge of the disk, energizing a ring of stars. The Sloan Digital Sky Survey has uncovered such a ring surrounding the galaxy at a reported distance of 120,000 light years.

Since dwarf galaxies and globular clusters revolve in the galactic plane along with the ring, logic suggests that one force is acting on both. Electromagnetism causes them all to be aligned at right angles to the axial intergalactic magnetic field, not gravity.

Conventional viewpoints acknowledge that galaxies form clusters, but it was not until recently that data analysis pointed to those clusters grouping together along vast filaments of “hot gas” that are more than a million degrees Celsius.

The filaments are actually Birkeland currents, perhaps thousands of light years thick and millions of light years long, out of which groups of galaxies are “pinched.” When we acknowledge that redshift is more a measure of youth than the distance of quasars, there is a possibility that the visible Universe is formed from braided filaments passing through the Virgo supercluster to the Fornax supercluster across millions of light years.
That, to me, seems a lot more rational than believing in the existence of yet another new speculative force and particle in order to keep the still unproven idea of dark matter alive yet another day. Just saying …
