Central Milky Way Black Hole eating NOT Stars but Herbig Haro Bowshock BlackHholes.

Central Milky Way Black Hole eating NOT Stars but dual Herbig Haro Bowshock ( Hotspot)  Black Holes leaving stars and plasma jets behind !!
.
According to Quantum FFF Theory, The central giant MW-Black Hole only eat dual systems of smaller black holes, also called Herbig Haro systems. HH systems create plasma jets in between which seem to stay put (see: streaks) after both HH black holes are eaten by the central BH. The image (by MEERKAT)does already show some dual grouping HH systems before the creation of  intermediate jets.

The main direction of the remaining Herbig Haro plasma jets is perpendicular to the Galaxy equator.
The most natural explanation according to quantum FFF Theory, is that in the Herbig Haro Black Hole Pairing process the Axion/Higgs field vacuum vector array profiles are equipped with an hourglass profile ( butterfly cross section)  with the central axis also perpendicular to the Galaxy equator.
As a consequence the two pairing HH black hole will polarize in the same way. see 2e image.

Open Transformable Rigid Strings in Quantum FFF theory

Quantum FFF Theory (Function Follows Form) is based on open rigid strings, derived from only one closed transformable  torus shaped mass less virgin string, also called "Axion Higgs" or "Tori varieties".
The Axion Higgs ring is assumed to be equipped with 3x internal rotation hinges with 90 degree rotation freedom and one splitting point.
Photons, Gluons, Neutrinos and two leptons (e+e-) are singular open singular monopole Strings, including Magnetic North and South monopole particles.
Fermions and Bosons are compound String knots containing two or more interconnected open strings.
Fermions are supposed to have a chiral form, a propeller shape with left or right handed pitch for positive or negative charge and spin.
Higgs particles come in two forms with reduced left or right handed pitch producing Higgs particles with 123.5 GeV or 126 Gev ( see image.)
A third Higgs is assumed to be based on 4x open strings with 375 GeV.
see below.
Black holes are assumed to be massive compound knots of virigin Axion Higgs particles without mass but with vacuum pressure gravity..

The consequence of this rigid string model leads to new physics of black holes, magnetic and gravitational interpretation.

Several attempts to describe comparable rigid string systems are done between 1980 and 2000, see:

Dual Stellar Anchor Black Holes by new physics of butterfly shaped spacetime polarization

Dual Stellar Anchor Black Holes by new physics of butterfly shaped spacetime polarization in combination with a new rigid propeller string theory for decrease of entropy and pair (negative charged plasma) production.

Quantum FFF Theory conjecture is, that spacetime can be polarized if it is represented by a 3D foam of a tetrahedral oscillating quantum lattice each with the local Planck length
Around black holes the Planck length is polarized with a vector array cross section in the form of a butterfly.
TWO black holes as observed around Herbig Haro Systems (the hotspot black holes) are  creating spacetime vector arrays of dual complexity ( see image below) in combination with vacuum push gravity for quick star formation.

I found your paper at:
https://arxiv.org/pdf/1805.01572.pdf called "Where are the Ultra High Energy Cosmic Ray (UHECR) originated?"
You wrote: under 2. "The Virgo Absence and the two Hot Spots"
"The Virgo UHECR event absence was (and still remains) the first and main Auger cosmic lesson recorded from more than a decade."
and:
"This remarkable Virgo absence is the Rosetta stone that forced us [ref.19], a decade ago, toward the lightest [20] UHECR nuclei nature.
Indeed we suggested the presence of a severe filter to stop the expected Virgo abundant UHECR events"

Quantum FFF Theory is a Vortex knot theory based on only one transformable but rigid torus particle called Axion/Higgs.

Quantum FFF Theory is a Vortex knot theory based on only one transformable but rigid torus particle coined Axion/Higgs.

Conclusion only the vacuum itself is based of simple rigid ring particles, oscillating along six chiral axes between common contact points, Fermions and Bosons can both come as single (electron/ positron /neutrino/photon and gluon) or compound  knots : (some leptons and all quarks and 3x Higgs  123.5- 126- 375 GeV.)
