Hints of FLRW Breakdown from Supernovae
Chethan Krishnan, Roya Mohayaee, Eoin Ó Colgáin +2
A 10\% difference in the scale for the Hubble parameter constitutes a clear problem for cosmology. Here, considering angular distribution of Type Ia supernovae (SN) within the Pant…
A Critique of Holographic Dark Energy
Eoin Ó Colgáin, M. M. Sheikh-Jabbari
Observations restrict the parameter space of Holographic Dark Energy (HDE) so that a turning point in the Hubble parameter is inevitable. Concretely, cosmic microwave backgr…
Lost in the Log-Polynomial Expansion: Comment on arXiv:2101.08278
Aritra Banerjee, Eoin Ó Colgáin, Misao Sasaki +1
In [1] we highlighted the fact that the log polynomial expansion employed in Nature Astron. 3, no.3, 272-277 (2019) [2] is a poor approximation to flat CDM, so using it to infer…
Elucidating cosmological model dependence with
E. Ó Colgáin, M. M. Sheikh-Jabbari
We observe that the errors on the Hubble constant , a universal parameter in any FLRW cosmology, can be larger in specific cosmological models than Gaussian Processes (GP) dat…
