21 cm power spectrum in interacting cubic Galileon model

We show the detectability of interacting and non-interacting cubic Galileon models from the $\mathrm{\Lambda }$CDM model through the 21 cm power spectrum. We show that the interferometric observations like the upcoming SKA1-mid can detect both the interacting and the non-interacting cubic Galileon model from the $\mathrm{\Lambda }$CDM model depending on the parameter values.
