Cosmological reconstruction and {\it Om} diagnostic analysis of
  Einstein-Aether Theory
  In this paper, we will analyse the cosmological models in Einstein-aether
gravity, which is a modified theory of gravity in which a time-like vector
field breaks the Lorentz symmetry. We will use this formalism to analyse
different cosmological models with different behavior of the scale factor. In
this analysis, we will use a certain functional dependence of the dark energy
on the Hubble parameter. It will be demonstrated that the aether vector field
has a non-trivial effect on these cosmological models. We will also perform the
\emph{Om} diagnostic in Einstein-aether gravity. Thus, we will fit parameters
of the cosmological models using recent observational data.
