Nonlinear structure formation in Bound Dark Energy

Erick Almaraz, Baojiu Li, Axel de la Macorra

We study nonlinear structure formation in the Bound Dark Energy model (BDE), where dark energy (DE) corresponds to a light scalar meson particle $ϕ$ dynamically formed at a condens…

Imprint of a Steep Equation of State in the growth of structure

Mariana Jaber, Erick Almaraz, Axel de la Macorra

We study the cosmological properties of a dynamical of dark energy (DE) component determined by a Steep Equation of State (SEoS) $w (z) = w_{0} + w_{i} \frac{( z / z _{T} ) ^{q}}{1 + ( z / z _{T} ) ^{q}}$ . The SE…

Bound Dark Energy: towards understanding the nature of the Dark Energy

Erick Almaraz, Axel de la Macorra

We present a complete analysis of the observational constraints and cosmological implications of our Bound Dark Energy (BDE) model aimed to explain the late-time cosmic acceleratio…
