Nettsider med emneord ?Smooth particle hydrodynamics?

The project consists in investigating the non-linear structure formation within the framework of dark energy, dark matter and modified gravity theories using N-body and hydrodynamic numerical simulations.

The physical reason for the observed acceleration of the Universe is one of the most important mysteries in cosmology, and arguably generally in fundamental physics.

Recently maturing software for stellar modeling and evolution, such as MESA, have been applied to constraining variations of the gravitational constant and exploring such a variation¡¯s ability to account for the Hubble tension between the late- and early- time universe by biasing the local distance ladder.

In HIDDEN we employ atomistic simulations (i) to establish the presence or not of a hidden geochemical reservoir in the deep mantle that can store noble gases, (ii) to calculate the permeability of the core-mantle boundary throughout geological time with respect to noble gases, (iii) to determine the exchanges of noble gases between the mantle and the core during the core formation, and (iv) to give estimates of fluxes of noble gases through the Earth¡¯s mantle throughout the geological time.
