A Dual Dwarf Galaxy Theorem

    The dark matter crisis: falsification of the current standard model of cosmology
    Pavel Kroupa (AIfA, Bonn)
    (Submitted on 11 Apr 2012 (v1), last revised 20 Jun 2012 (this version, v2))
    The current standard model of cosmology (SMoC) requires The Dual Dwarf Galaxy Theorem to be true according to which two types of dwarf galaxies must exist: primordial dark-matter (DM) dominated (type A) dwarf galaxies, and tidal-dwarf and ram-pressure-dwarf (type B) galaxies void of DM. Type A dwarfs surround the host approximately spherically, while type B dwarfs are typically correlated in phase-space. Type B dwarfs must exist in any cosmological theory in which galaxies interact. Only one type of dwarf galaxy is observed to exist on the baryonic Tully-Fisher plot and in the radius-mass plane. The Milky Way satellite system forms a vast phase-space-correlated structure that includes globular clusters and stellar and gaseous streams. Other galaxies also have phase-space correlated satellite systems. Therefore, The Dual Dwarf Galaxy Theorem is falsified by observation and dynamically relevant cold or warm DM cannot exist. It is shown that the SMoC is incompatible with a large set of other extragalactic observations. Other theoretical solutions to cosmological observations exist. In particular, alone the empirical mass-discrepancy--acceleration correlation constitutes convincing evidence that galactic-scale dynamics must be Milgromian. Major problems with inflationary big bang cosmologies remain unresolved.
    Comments: Publications of the Astronomical Society of Australia (CSIRO Publishing), LaTeX, 51 pages, 16 figures. Minor changes: The Dual Dwarf Galaxy Theorem has been corrected, two additional failures of the SMoC added. The paper is published online early as an open access article here: this http URL . It will appear in press in the December 2012 issue of PASA

    Does this falsify cold dark matter?

    does this mean cold dark matter searches like Lux Zeppelin and SuperCDMS will fail to find any evidence of DM?
    what are implications for SUSY

    This paper gets a giant eye roll from me.

    It makes some pretty wild claims. The validity of those claims, however, necessarily rests upon some extremely complicated physics of normal matter. Whether or not there should be a lot of observed dwarf galaxies with little dark matter depends critically upon how those dwarf galaxies form. But the physics of how this occurs is still exceedingly uncertain.

    I am generally very unsatisfied with claims that the standard model of cosmology is wrong that come exclusively from the subset of cosmological observations where unknown systematic errors are most likely to be.

    Pavel kroupa is no stranger to publishing cow pie recipes, I so not take him seriously.
