The origin of dark matter
WebbIn this paper, we study the dynamical stability and time-evolution of the central dark matter cores of low-mass (about 10 8 -10 9 M solar ) galactic haloes found in recent cold dark matter simulations at high redshift. From these simulations we extract three haloes, assembled by hierarchical merging, that at redshift z>~ 10 display a core, and we … Webb12 apr. 2024 · Scientists using a telescope in Chile have produced groundbreaking new map of “dark matter” in 25% of the night sky that they say supports Albert Einstein’s …
