Latest Cold dark matter Stories
A team of Australian astrophysicists has determined that the Milky Way has half as much dark matter as previously thought, according to a new study published in the Astrophysical Journal.
Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected.
For decades, the mystery of Dark Matter has been at the forefront of physics research. Since the 1930s, scientists have been aware that all of the mass that we can see – the stars, the dust, the planets, and black holes – makes up only 20 percent of the Universe.
A research team is hunting for a theorized but never-before-seen elementary particle called an axion that may be at the heart of dark matter.
Researchers found that the density of the dark matter was greater near the center of the galaxy clusters, on average, gradually becoming more diffuse moving out towards the cluster’s edge. This is consistent with a cold dark matter model, which, along with other evidence, has been the leading candidate theory for some years.
Scientists at the institute have found that a phenomenon known as “cosmic web stripping” is responsible for the lack of dwarf galaxies near the Milky Way that should be there according to the theory of cold dark matter and dark energy.
Astronomers have developed an algorithm that is able to chart and explain accurately the structure and dynamics of the universe.
Two teams of astronomers have used data from NASA's Chandra X-ray Observatory and other telescopes to map the distribution of dark matter in a galaxy cluster known as Abell 383, which is located about 2.3 billion light years from Earth.
Like all galaxies, our Milky Way is home to a strange substance called dark matter. Dark matter is invisible, betraying its presence only through its gravitational pull.
'Bolshoi' supercomputer simulation provides new benchmark for cosmological studies.
