Hubble tension is routinely presented as a mismatch between the Hubble constant determined locally and a value inferred from the flat CDM cosmology. In essence, the tensio…

Is there an early Universe solution to Hubble tension?
Chethan Krishnan, Eoin Ó Colgáin, Ruchika +3
We consider a low redshift cosmological dataset comprising megamasers, cosmic chronometers, type Ia SNe and BAO, which we bin according to their redshift. For each bin, w…

A hint of matter underdensity at low ?
Eoin Ó Colgáin
The CDM cosmological model provides to first approximation a good description of the universe, but various tensions with data, most notably Hubble tension, persist. In this work…
