A Prediction for DESI Full-Shape: Increasing Tomographic Trend
Eoin Ó Colgáin, M. M. Sheikh-Jabbari
To confirm CDM deviations are due to missing physics (not systematics), one should demonstrate that the model fitting parameters exhibit qualitatively similar redshift drift acr…
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…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
DESI and SNe: Dynamical Dark Energy, Tension or Systematics?
Eoin Ó Colgáin, M. M. Sheikh-Jabbari
Dark Energy Spectroscopic Instrument (DESI) observations, when combined with Cosmic Microwave Background (CMB) and Type Ia supernovae (SNe), have led to statistically significant d…
Implications of DES 5YR SNe Dataset for CDM
Eoin Ó Colgáin, Saeed Pourojaghi, M. M. Sheikh-Jabbari
Dark Energy Survey five-year supernovae data (DES 5YR SNe) in conjunction with Planck CMB and Dark Energy Spectroscopic Instrument (DESI) BAO data has detected a strong dynamical d…
Does DESI 2024 Confirm CDM?
Eoin Ó Colgáin, Maria Giovanna Dainotti, Salvatore Capozziello +3
We demonstrate that a discrepancy with the Planck-CDM cosmology in DESI Luminous Red Galaxy (LRG) data in the redshift range with effective redshift $…
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…
Does Hubble Tension Signal a Breakdown in FLRW Cosmology?
Chethan Krishnan, Roya Mohayaee, Eoin Ó Colgáin +2
The tension between early and late Universe probes of the Hubble constant has motivated various new FLRW cosmologies. Here, we reanalyse the Hubble tension with a recent age of the…
On Problems with Cosmography in Cosmic Dark Ages
Aritra Banerjee, Eoin Ó Colgáin, Misao Sasaki +2
Quasars show considerable promise as standard candles in a high-redshift window beyond Type Ia supernovae. Recently, Risaliti, Lusso \& collaborators \cite{Risaliti:2018reu, Lusso:…
Cosmology Intertwined II: The Hubble Constant Tension
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +90
The current cosmological probes have provided a fantastic confirmation of the standard Cold Dark Matter cosmological model, that has been constrained with unprecedented accurac…
