Unprecedentedly wide and sharp dark matter map

Subaru Telescope

The standard cosmological model (called LCDM) incorporates the cosmological constant. Wide and deep imaging survey using Hyper Suprime-Cam Figure 2: Expansion history of the Universe. Figure 3: Hyper Suprime-Cam image of a location with a highly significant dark matter halo detected through the weak gravitational lensing technique. This 3-D dark matter mass map is also quite new. What the dark matter halo count suggests and future prospects Figure 4: An example of 3D distribution of dark matter reconstructed via tomographic methods using the weak lensing technique combined with the redshift estimates of the background galaxies.
