Crosschecking Cosmic Distances from DESI BAO and DES SNe

Mauricio Lopez-Hernandez, Eoin Ó Colgáin, Saeed Pourojaghi +1

We perform a consistency check of DESI DR2 BAO constraints ( by reconstructing the same quantities from DES supernovae (SNe) in bins with the same effective reds…

CDM Tensions: Localising Missing Physics through Consistency Checks

Özgür Akarsu, Eoin Ó Colgáin, Anjan A. Sen +1

CDM tensions are by definition model dependent; one sees anomalies through the prism of CDM. Thus, progress towards tension resolution necessitates checking the consistency o…

increases with effective redshift in CDM cosmology

Shahnawaz A. Adil, Özgür Akarsu, Mohammad Malekjani +4

Hubble constant and weighted amplitude of matter fluctuations determinations are biased to higher and lower values, respectively, in the late Universe with respect to e…

Inevitable manifestation of wiggles in the expansion of the late Universe

Ozgur Akarsu, Eoin O. Colgain, Emre Ozulker +2

Using the fact that the comoving angular diameter distance to the last scattering surface is strictly constrained almost model independently, we show that, for any model agreeing w…

Is the Observable Universe Consistent with the Cosmological Principle?

Pavan Kumar Aluri, Paolo Cea, Pravabati Chingangbam +20

The Cosmological Principle (CP) -- the notion that the Universe is spatially isotropic and homogeneous on large scales -- underlies a century of progress in cosmology. It is conven…
