Hubble Tension: The Evidence of New Physics
Universe, 2023 The ΛCDM model provides a good fit to most astronomical observations but harbors large areas of phenomenology and ignorance. With the improvements in the precision and number of observations, discrepancies between key cosmological parameters of this ...Jian-Ping Hu, Fa-Yin Wangdoaj +1 more sourceSTATEFINDER PARAMETERS FOR FIVE-DIMENSIONAL COSMOLOGY [PDF]
Modern Physics Letters A, 2008 We study the statefinder parameter in the five-dimensional big bounce model, and apply it to differentiate the attractor solutions of quintessence and phantom field. It is found that the evolving trajectories of these two attractor solutions in the statefinder parameters plane are quite different, and that are different from the statefinder ...Chang, Baorong, Liu, Hongya, Xu, Lixin, Zhang, Chengwu +3 moreopenaire +3 more sourcesCosmological parameters from SDSS and WMAP

The Astrophysical Journal, 2009 Chandra observations of large samples of galaxy clusters detected in X-rays by ROSAT provide a new, robust determination of the cluster mass functions at low and high redshifts. Statistical and systematic errors are now sufficiently small, and the redshift leverage sufficiently large for the mass function evolution to be used as a useful growth of ...Vikhlinin, A., Kravtsov, A.
