Abstract

Motivated by the recent Year-2 data release of the DESI collaboration, we update our results on time-varying dark energy models driven by the Cohen-Kaplan-Nelson bound. The previously found preference of time-dependent dark energy models compared to ΛCDM is further strengthend by the new data release. For our particular models, we find that this preference increases up to ≈ 2.6 σ depending on the used supernova dataset.
附录:用Cohen-Kaplan-Nelson界驱动的暗能量拟合DESI BAO数据
受DESI合作最近发布的第2年数据的激励,我们更新了由Cohen-Kaplan-Nelson边界驱动的时变暗能量模型的结果。先前发现的与时间相关的暗能量模型与ΛCDM相比的偏好被新发布的数据进一步加强。对于我们的特殊模型,我们发现根据使用的超新星数据集,这种偏好增加到≈2.6 σ。

期刊介绍: Journal of Cosmology and Astroparticle Physics (JCAP) encompasses theoretical, observational and experimental areas as well as computation and simulation. The journal covers the latest developments in the theory of all fundamental interactions and their cosmological implications (e.g. M-theory and cosmology, brane cosmology). JCAP''s coverage also includes topics such as formation, dynamics and clustering of galaxies, pre-galactic star formation, x-ray astronomy, radio astronomy, gravitational lensing, active galactic nuclei, intergalactic and interstellar matter.
