Webb19 aug. 2024 · The universe is estimated to be made up of 4.9% ordinary (baryonic) matter, 26.8% dark matter, and 68.3% dark energy. Considering only the largest structures, the universe is made up of filaments, voids, superclusters, and galaxy groups, and clusters. Dark matter and dark energy are invisible theoretical matter. WebbCold interstellar gas systems have been used to constrain dark matter (DM) models by the condition that the heating rate from DM must be lower than the astrophysical cooling rate of the gas. Following the methodology of Wadekar and Farrar (2024), we use the interstellar medium of a gas-rich dwarf galaxy, Leo T, and a Milky Way-environment gas cloud, G33.4 …
