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-consistent…
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…
Filling the radio transients gap (or: The case for a dedicated radio transients monitoring array in the southern hemisphere)
Rob Fender, Assaf Horesh, Phil Charles +3
In this short paper we outline the case for a small radio telescope array in the southern hemisphere with operations dedicated to rapid follow-up and monitoring of astrophysical tr…
MID-Radio Telescope, Single Pixel Feed Packages for the Square Kilometre Array: An Overview
Alice Pellegrini, Jonas Flygare, Isak P. Theron +10
The Square Kilometre Array (SKA) project is an international effort to build the world s largest radio telescope, enabling science with unprecedented detail and survey speed. The p…
Hierarchical clustering and the BAO signature
Wojciech A. Hellwing, Roman Juszkiewicz, Rien van de Weygaert +1
In this contribution we present the preliminary results regarding the non-linear BAO signal in higher-order statistics of the cosmic density field. We use ensembles of N-body simul…
Particle Dark Matter: the state of the art
Marco Regis
Although well established observations on cosmological, cluster, and galactic scales strongly suggest the existence of dark matter (DM), our understanding of its non-gravitational…
