Constraining Born-Infeld models of dark energy with CMB anisotropies

L. Raul Abramo, Fabio Finelli, Thiago S. Pereira

We study the CMB constraints on two Dark Energy models described by scalar fields with different Lagrangians, namely a Klein-Gordon and a Born-Infeld field. The speed of sound of f…
