High Redshift CDM Cosmology: To Bin or not to Bin?
Eoin Ó Colgáin, M. M. Sheikh-Jabbari, Rance Solomon
We construct observational Hubble and angular diameter distance mock data with baseline Planck CDM input values, before fitting the CDM model to study evolu…
Putting Flat CDM In The (Redshift) Bin
Eoin Ó Colgáin, M. M. Sheikh-Jabbari, Rance Solomon +2
Flat CDM cosmology is specified by two constant fitting parameters at the background level in the late Universe, the Hubble constant and matter density (today) . Math…
Quasar standardization: Overcoming Selection Biases and Redshift Evolution
Maria Giovanna Dainotti, Giada Bardiacchi, Aleksander Lukasz Lenart +5
Quasars (QSOs) are extremely luminous active galatic nuclei currently observed up to redshift . As such, they have the potential to be the next rung of the cosmic distance…
Revealing Intrinsic Flat CDM Biases with Standardizable Candles
Eoin Ó Colgáin, M. M. Sheikh-Jabbari, Rance Solomon +4
Emerging high redshift cosmological probes, in particular quasars (QSOs), show a preference for larger matter densities, , within the flat CDM framework. Here,…
Environment Dependent Electron Mass and the H-Tension
Rance Solomon, Garvita Agarwal, Dejan Stojkovic
A difference in the electron mass at recombination from the measured value today has been shown to relieve the Hubble tension. In this article we propose a simple mechanism that wo…
