Is Dark Energy Increasing or Decreasing in the Late Universe?
Maryam Aghaei Abchouyeh, Maurice H. P. M. van Putten
The concordance cosmological model CDM assumes dark energy to be a constant, consistent with early-time observations, evidenced by Planck-CDM analyses. However, in the face o…
Prospects for high-resolution probes of galaxy dynamics tracing background cosmology in MaNGA
Gyeong-Min Lee, Maurice H. P. M. van Putten
Large- galaxy surveys offer unprecedented opportunities to probe weak gravitation in galaxy dynamics that may contain correlations tracing background cosmology. Of particular in…
On the Hubble expansion in a Big Bang quantum cosmology
Maurice H. P. M. van Putten
The Hubble expansion of the Universe is considered in the classical limit of a Big Bang quantum cosmology. In an IR-consistent coupling to the the bare cosmological constant, we in…
A doublet of cosmological models to challenge the H0 tension in the Pantheon Supernovae Ia catalog
B. De Simone, M. H. P. M. van Putten, M. G. Dainotti +1
CDM provides a leading framework in the interpretation of modern cosmology. Nevertheless, the scientific community still struggles with many open problems in cosmology. Among t…
