The road towards precision measurements of with bright sirens in the Einstein Telescope era
Chiara De Leo, Elsa M. Teixeira, Vivian Poulin
Gravitational-wave standard sirens provide an independent probe of cosmic expansion since their luminosity distances are inferred directly from the gravitational-wave signal and, f…

Interacting dark sector from intrinsic entropy couplings
Erik Jensko, Elsa M. Teixeira, Vivian Poulin
We introduce a new class of interacting dark sector models that couple the intrinsic entropy of dark matter to scalar field dark energy. Using the Lagrangian formulation for relati…

Interactions in the dark sector: intrinsic entropy couplings
Elsa M. Teixeira
We present a new class of interacting dark sector models in which the intrinsic entropy of a dark matter fluid couples to a scalar field describing dark energy. These interactions…
