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…

Modified gravity for surveys

Luisa G. Jaime, Mariana Jaber, Celia Escamilla-Rivera

We present a new parameterization for the equation of state (EoS) $ω_{X} = P_{X} / ρ_{X}$ , which can reproduce a $f (R)$ -like evolution with a precision between $[0.5% - 0.8%]$ over the numer…

Probing a Steep EoS for Dark Energy with latest observations

Mariana Jaber, Axel de la Macorra

We present a parametrization for the Dark Energy Equation of State "EoS" which has a rich structure, performing a transition at pivotal redshift $z_{T}$ between the present day value…
