Gravitational signals can help measure the viscosity of dark matter in the future
2021.03.29 10:49 - Marek PawłowskiIf gravitational waves traveled through a medium filled with sticky dark matter, then the wave amplitude would be (weakly) damped. The analysis of this effect could shed new light on the nature of dark matter - argues Prof. Marek Biesiada (from the NCBJ Astrophysics Department) together with Chinese colleagues in a study published in the Monthly Notices of the Royal Astronomical Society: Letters.
