"This discovery poses a challenge to the Lambda Cold Dark Matter model, which may struggle to account for the formation of such small, aligned groups of galaxies in isolated environments." When you ...

The dark matter distribution of a Milky Way mass halo in a Lambda-cold dark matter (LCDM) cosmological simulation. This is the highest resolution simulation of a MW-mass dark matter halo ever ...

For more than two decades, the standard model of cosmology has stood as a reliable guide to the universe. Known as Lambda Cold Dark Matter, or ΛCDM, it weaves together dark energy, dark matter, and ...

Dark energy is responsible for the expansion of the Universe, but its true nature is still a subject of much debate. Computer simulations based on the latest astronomical data enable scientists to ...
