One of the foundations of the concordance cosmological model is that approximately 85 per cent of the matter content of the Universe is in the form of some yet unknown component that we can detect only through its gravitational effect: dark matter. While the standard Cold Dark Matter model is very successful at explaining the large scale structure distribution of the universe, it has been...

Milgromian dynamics (or Modified Newtonian Dynamics, MOND) is a major alternative to particle dark matter proposed in 1983 by Mordehai Milgrom. MOND modifies the non-relativistic laws of gravity and/or inertia at low accelerations, below a characteristic acceleration scale a0.

Accurate polarization angle calibration of Cosmic Microwave Background (CMB) telescopes constitutes a critical challenge in modern observational cosmology.
