Hubble tension in k-essence: Evidence for robust tension alleviation
Isaac Opio, Didam Duniya, Bishop Mongwane +1
The Hubble tension has come to stay as a major problem in modern cosmology as it continues to plague the standard cosmological model (CDM). As one of the viable, self-consisten…
Relativistic effects in k-essence
Didam Duniya, Isaac Opio, Bishop Mongwane +1
Relativistic effects are sensitive to subtle changes in dark energy. These effects grow on very large scales and at high redshifts, which will be the reach of upcoming surveys. We…
Investigating the imprint of quintessence in cosmic magnification
Enas Mohamed, Didam Duniya, Hassan Abdalla +1
We study cosmic magnification beyond lensing in a late-time universe dominated by quintessence and cold dark matter. The cosmic magnification angular power spectrum, especially goi…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
White Paper and Roadmap for Quantum Gravity Phenomenology in the Multi-Messenger Era
R. Alves Batista, G. Amelino-Camelia, D. Boncioli +101
The unification of quantum mechanics and general relativity has long been elusive. Only recently have empirical predictions of various possible theories of quantum gravity been put…
