Massive compact halo object
A Massive Compact Halo Object (MACHO) is a hypothetical type of astronomical object that is proposed to exist in the halo of galaxies, particularly the Milky Way. MACHOs are believed to be composed of ordinary matter, mainly in the form of objects such as brown dwarfs, white dwarfs, neutron stars, or even black holes. They are "compact" because they have a relatively small size compared to their mass, leading to a high density.
Mixed dark matter
Mixed dark matter refers to a theoretical framework in cosmology and astrophysics that posits the existence of multiple types of dark matter particles, which can have different properties and behaviors. Generally, dark matter is understood as a form of matter that does not emit, absorb, or reflect light, making it undetectable by traditional astronomical instruments. Instead, its presence is inferred from gravitational effects on visible matter, radiation, and the large-scale structure of the universe.
