Crosschecking Cosmic Distances from DESI BAO and DES SNe
Mauricio Lopez-Hernandez, Eoin à 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…
An FWCI decomposition of Science Foundation Ireland funding
Eoin à Colgáin
In response to the 2008 global financial crisis, Science Foundation Ireland (SFI), now Research Ireland, pivoted to research with potential socioeconomic impact. Given that the lat…
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.…
Does DESI 2024 Confirm CDM?
Eoin à 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…
Implications of DES 5YR SNe Dataset for CDM
Eoin à 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…
DESI and SNe: Dynamical Dark Energy, Tension or Systematics?
Eoin à 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…
