On frequentist confidence intervals in a non-Gaussian regime
Shubham Barua, Shantanu Desai, Mauricio Lopez-Hernandez +1
We study frequentist confidence intervals based on graphical profile likelihoods (Wilks' theorem, likelihood integration), and the Feldman-Cousins (FC) prescription, a generalisati…
On the Analysis Dependence of DESI Dynamical Dark Energy
Eoin Ó Colgáin, Saeed Pourojaghi, M. M. Sheikh-Jabbari
We continue scientific scrutiny of the DESI dynamical dark energy (DE) claim by explicitly demonstrating that the result depends on the analysis pipeline. Concretely, we define a l…
Is Local At Odds With Dark Energy EFT?
Bum-Hoon Lee, Wonwoo Lee, Eoin Ó Colgáin +2
Local determinations currently fall in a window between km/s/Mpc (TRGB) and km/s/Mpc (Tully-Fisher). In contrast, BAO data calibrated in an early…
Can dark energy be dynamical?
Eoin Ó Colgáin, M. M. Sheikh-Jabbari, Lu Yin
We highlight shortcomings of the dynamical dark energy (DDE) paradigm. For parametric models with equation of state (EOS), for a given function of redshift…
Cosmography and flat CDM tensions at high redshift
Tao Yang, Aritra Banerjee, Eoin Ó Colgáin
Risaliti, Lusso \& collaborators have constructed a high-redshift Hubble diagram of supernovae (SNe); quasars (QSO) and gamma-ray bursts (GRB) that shows a " tension w…
de Sitter Swampland, tension & observation
Eoin Ó Colgáin, Maurice H. P. M. van Putten, Hossein Yavartanoo
Realising de Sitter vacua in string theory is challenging. For this reason it has been conjectured that de Sitter vacua inhabit the Swampland of inconsistent low-energy effective t…
