How much has DESI dark energy evolved since DR1?

Eoin Ó Colgáin, Saeed Pourojaghi, M. M. Sheikh-Jabbari +1

DESI has reported a dynamical dark energy (DE) signal based on the $w_{0} w_{a}$ CDM model that is in conflict with Hubble tension. Recalling that the combination of DESI DR1 BAO and DR…

Further support for $S_{8}$ increasing with effective redshift

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

In Adil et al. 2023, we reported an increasing trend in $S_{8}$ with effective redshift $z_{eff}$ based on $f σ_{8} (z)$ constraints over the redshift range $0 \lesssim z \less…

Holographic integration of $T T ˉ$ and $J T ˉ$ via $O (d, d)$

Thiago Araujo, Eoin Ó Colgáin, Yuho Sakatani +2

Prompted by the recent developments in integrable single trace $T T ˉ$ and $J T ˉ$ deformations of 2d CFTs, we analyse such deformations in the context of $A d S_{3} / C F T_{2}$ fro…
