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…
