How To See the Invisible: Measuring Dark Matter With Hyper Suprime-Cam Reveals Discrepancy

Using the Hyper Suprime-Cam (HSC), a team led by Princeton University has studied the distribution of dark matter and found a discrepancy between the 'clumpiness' (S8 value) of dark matter in the present universe versus the early universe. This discrepancy could point to an unrecognized error or hin
