Abstract
We study detectability of the deviation in interacting and non-interacting cubic Galileon models from the \(\Lambda \)CDM model through the 21-cm power spectrum. We show that the interferometric observations like the upcoming SKA1-mid can detect the deviations in both interacting and non-interacting cubic Galileon model from the \(\Lambda \)CDM model depending on the parameter values.
