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 ....

How to see the invisible: Using the dark matt

Astrophysicists led by Princeton University and the astronomical communities of Japan and Taiwan have measured a value for the “clumpiness” of the universe’s dark matter (known to cosmologists as “S8”) of 0.776, which does not align with the value derived from the Cosmic Microwave Background, which dates back to the universe’s origins. This has intriguing implications for the standard cosmological model. ....
