1 Oct 2020 | | Abstract: | The standard model of cosmology, the $Lambda$CDM model, describes the
evolution of the Universe since the Big Bang with just a few parameters, six in
its basic form. Despite being the simplest model, direct late-time measurements
of the Hubble constant compared with the early-universe measurements result in
the so-called $H_0$ tension. It is claimed that a late time resolution is
predestined to fail when different cosmological probes are combined. In this
work, we shake the ground of this belief with a very simple model. We show how,
in the context of cubic vector Galileon models, the Hubble tension can
naturally be relieved using a combination of CMB, BAO and SNe observations
without using any prior on $H_0$ . The tension can be reduced even further by
including the local measurement of the Hubble constant. | | Source: | arXiv, 2010.00513 | | Services: | Forum | Review | PDF | Favorites | |
