Cosmological perturbations with ultralight vector dark matter fields: numerical implementation in CLASS

Tomás Ferreira Chase, Matías Leizerovich, Diana López Nacir +1

In this work we consider a dark matter candidate described by an ultralight vector field, whose mass is in principle in the range $H_{\mathrm{eq}}\sim 10^{-28}\mathrm{eV}\ll \mathrm{m}<\mathrm{eV}$. T…
