WebJan 13, 2024 · We investigate a cosmological scenario in which the dark matter particles can be created during the evolution of the Universe. By regarding the Universe as an open thermodynamic system and using non-equilibrium thermodynamics, we examine the mechanism of gravitational particle production. WebFrom this point on, and for several billion years to come, the presence of dark matter accelerates the formation of structure in the universe. In the early universe, dark matter gradually gathers in huge filaments under …
WebWe formulate an effective theory of structure formation (ETHOS) that enables cosmological structure formation to be computed in almost any microphysical model of dark matter physics. This framework maps the detailed mi… WebMar 22, 2024 · 1 INTRODUCTION. In the hierarchical picture of structure formation, dark matter haloes grow by accreting a mixture of smaller haloes and smooth matter (depending on the nature of the dark matter particles; e.g. Lacey & Cole 1993).We observe indirect evidence for this process in the form of rising galaxy luminosity functions (e.g. Muzzin et …
WebDark matter is a hypothetical form of matter thought to account for approximately 85% of the matter in the universe. [1] Dark matter is called "dark" because it does not appear to interact with the electromagnetic field, which means it does not absorb, reflect, or emit electromagnetic radiation and is, therefore, difficult to detect.
