ACT DR6 Leads to Stronger Evidence for Dynamical Dark Matter
Deng Wang, Kazuharu Bamba
Dark matter is fundamental to the composition, structure, and evolution of the universe. Combining the ACT's cosmic microwave background, DESI's baryon acoustic oscillations with D…
Evidence for Dynamical Dark Matter
Deng Wang
The nature of dark matter is one of the most fundamental questions in cosmology. Using the cosmic microwave background (CMB), type Ia supernova (SN) and DESI's new measurements of…
Questioning Cosmic Acceleration with DESI: The Big Stall of the Universe
Deng Wang
One of the most important discoveries in modern cosmology is cosmic acceleration. However, we find that today's universe could decelerate in the statistically preferred Chevallier-…
Evidence for Cosmological Massive Neutrinos
Deng Wang
A key question in cosmology is whether massive neutrinos exist on cosmic scales. Current cosmological observations have severely compressed the viable range for neutrino masses and…
