Phantom of Ramses (PoR) code for galaxy formation and evolution in
With a small grant from the Rectorate of the University of Bonn PK
received in 2013, Fabian Lueghausen (in collaboration with Benoit Famaey and
Pavel Kroupa) was able to develop in 2014 and 2015 a patch to Romain
Teyssier's RAMSES code to allow dark-matter-free high-resolution simulations of galaxy formation and
Lueghausen, Famaey & Kroupa 2015 Phantom of Ramses (PoR) code is a
patch to RAMSES. By default the patch comes with the
RAMSES code whenever it is downloaded.
Close scrutiny of such claims made by the standard-cosmology teams
have until now always yielded flaws in the applied analysis. Is this a
result of over-motivation to demonstrate that LCDM works? In the above
Ibata et al. 2015 rebuttal, the authors write in their abstract:
"All these unexpected correlations strongly suggest that a
substantial fraction of satellite galaxies are causally-linked in
their formation and evolution.", in agreement with the conclusions
reached independently elsewhere that most, if not all, dSph and UFD
satellites are old tidal dwarf galaxies without particle dark matter
(2012a, 2012b and 2015; see also 1997).

We document on the web, as best we can and within our spare time, the
paradigm change away from the concordance or standard cold or warm dark
matter based cosmological models (the LCDM or LWDM models) towards a
new understanding of cosmological physics.
