The homogeneity scale and the growth rate of cosmic structures
Felipe Avila, Armando Bernui, Rafael C. Nunes +2
We propose a novel approach to obtain the growth rate of cosmic structures, , from the evolution of the cosmic homogeneity scale, . Our methodology needs two…
Late time interacting cosmologies and the Hubble constant tension
Stefano Gariazzo, Eleonora Di Valentino, Olga Mena +1
In this manuscript we reassess the potential of interacting dark matter-dark energy models in solving the Hubble constant tension. These models have been proposed but also question…
No slip gravity in light of LISA standard sirens
Alireza Allahyari, Rafael C. Nunes, David F. Mota
Standard sirens (SS) are the gravitational wave analog of the astronomical standard candles, and can provide powerful information about the dynamics of the Universe up to very high…
Search for sub-solar mass binaries with Einstein Telescope and Cosmic Explorer
Rafael C. Nunes
A possible detection of sub-solar mass ultra-compact objects would lead to new perspectives on the existence of black holes that are not of astrophysical origin and/or pertain to f…
Dark sector interaction and the supernova absolute magnitude tension
Rafael C. Nunes, Eleonora Di Valentino
It has been intensively discussed if modifications in the dynamics of the Universe at late times is able or not to solve the tension. On the other hand, it has also been argu…
Arbitrating the discrepancy with growth rate measurements from Redshift-Space Distortions
Rafael C. Nunes, Sunny Vagnozzi
Within the CDM model, measurements from recent Cosmic Microwave Background (CMB) and weak lensing (WL) surveys have uncovered a disagreement in the inferred value of t…
Minimal theory of massive gravity in the light of CMB data and the tension
Jose C. N. de Araujo, Antonio De Felice, Suresh Kumar +1
We investigate the Minimal Theory of Massive Gravity (MTMG) in the light of different observational data sets which are in tension within the CDM cosmology. In particular, we an…
Observational Constraints on the Pulsar Wind Model: The Cases of Crab and Vela
Jaziel G. Coelho, José C. N. de Araujo, Samantha M. Ladislau +1
As is well known, pulsars are extremely stable rotators. However, although slowly, they spin down thanks to brake mechanisms, which are in fact still subject of intense investigati…
Reconstruction of the dark sectors' interaction: A model-independent inference and forecast from GW standard sirens
Alexander Bonilla, Suresh Kumar, Rafael C. Nunes +1
Interacting dark matter (DM) - dark energy (DE) models have been intensively investigated in the literature for their ability to fit various data sets as well as to explain some ob…
