Ultralight scalars as cosmological dark matter Open
Many aspects of the large-scale structure of the Universe can be described successfully using cosmological models in which 27 ± 1% of the critical mass-energy density consists of cold dark matter (CDM). However, few—if any—of the predictio…

Early Dark Energy can Resolve the Hubble Tension Open
Early dark energy (EDE) that behaves like a cosmological constant at early times (redshifts z≳3000) and then dilutes away like radiation or faster at later times can solve the Hubble tension. In these models, the sound horizon at decouplin…
