Self-Interacting Cold Dark Matter Haloss predicted by cosmological models. Weak self-interaction leads to the formation of an isothermal, low-density core which is in agreement with published data on the rotation curves of dwarf galaxies. However, subsequently, core collapse leads to an even steeper central density cusp. In order to explErgots 发表于 2025-3-28 20:32:09
Evidence for Dark Energy from a Study of Type Ia Supernovaeed over 80 such distant supernovae with redshifts between 0.18 and 1.2. In a study of 42 of these supernovae and comparison with 18 “near by” supernovae we have obtained evidence that at the present epoch the expansion of the universe is accelerating. This implies the presence of a positive cosmologAerate 发表于 2025-3-29 02:49:42

Can Quintessence Be Natural?eld theoretical models. The quintessence lagrangian is taken to be the sum of a simple exponentialpotential and a non-canonical kinetic term. This parameterization covers most variantsof quintessence and makes the naturalness conditions particularly transparent. Several “natural” scalar models lead,飓风 发表于 2025-3-29 10:00:22

In a recent study of 32 extended and well-measured galactic rotation curves, we found evidence for this law.强壮 发表于 2025-3-29 22:10:28

Monika Ankele,Céline Kaiser,Sophie Ledeburameterization covers most variantsof quintessence and makes the naturalness conditions particularly transparent. Several “natural” scalar models lead, for the present cosmological era, to a large fraction ofhomogeneous dark energy density and an acceleration of the scale factor as suggestedby observation.Bumptious 发表于 2025-3-30 05:10:36
