I like knedliky and dark matter. But knedliky can be eaten while dark matter cannot. Also, dark matter does not appear to exist. (adapted from Jaroslav Haas, Oct.2nd, 2019 in Praha when introducing my colloquium on the IMF)

2015: Phantom of Ramses (PoR) code for galaxy formation and evolution in Milgromian dynamics/MOND:

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 evolution.
The Phantom of Ramses (PoR) code is a patch to RAMSES. By default the patch comes with the RAMSES code whenever it is downloaded.
