A goal of this work is to study the influence of feedback on halo.  Specially, I'm trying to quantify the change in the SFR for different class of halo mass.  Has seen in the CODA simulation (\cite{ocvirk_cosmic_2015}), \cite{ocvirk_cosmic_2015},  I'm expecting a diminution of the instantaneous SFR in the less massive halo ($M<10^9M_{\odot}$) ($M<10^9M_{\odot}$).
