Dark calling Dark: Interaction in the dark sector in presence of neutrino properties after Planck CMB final release
Weiqiang Yang, Supriya Pan, Rafael C. Nunes +1
We investigate a well known scenario of interaction in the dark sector where the vacuum energy is interacting with cold dark matter throughout the cosmic evolution in light of the…
Forecasts on the speed of gravitational waves at high
Alexander Bonilla, Rocco D'Agostino, Rafael C. Nunes +1
The observation of GW170817 binary neutron star (BNS) merger event has imposed strong bounds on the speed of gravitational waves (GWs) locally, inferring that the speed of GWs prop…
Probing observational bounds on scalar-tensor theories from standard sirens
Rocco D'Agostino, Rafael C. Nunes
Standard sirens are the gravitational wave (GW) analog of the astronomical standard candles, and can provide powerful information about the dynamics of the Universe. In this work,…
Listening to the sound of dark sector interactions with gravitational wave standard sirens
Weiqiang Yang, Sunny Vagnozzi, Eleonora Di Valentino +3
We consider two stable Interacting Dark Matter -- Dark Energy models and confront them against current Cosmic Microwave Background data from the \textit{Planck} satellite. We then…
Forecast constraints on gravity with gravitational waves from compact binary coalescences
Rafael C. Nunes, Marcio E. S. Alves, Jose C. N. de Araujo
The direct detection of gravitational waves (GWs) opened a new chapter in the modern cosmology to probe possible deviations from the general relativity (GR) theory. In the present…
Dark sector interaction: a remedy of the tensions between CMB and LSS data
Suresh Kumar, Rafael C. Nunes, Santosh Kumar Yadav
The well-known tensions on the cosmological parameters and within the CDM cosmology shown by the Planck-CMB and LSS data are possibly due to the systematics in the d…
Testing the warmness of dark matter
Suresh Kumar, Rafael C. Nunes, Santosh Kumar Yadav
Dark matter (DM) as a pressureless perfect fluid provides a good fit of the standard CDM model to the astrophysical and cosmological data. In this paper, we investigate two exte…
