\section{Introduction}
Simple and productive methods to investigate dynamical features
of solids and molecules are offered by Time-dependent Density-functional Theory (TDDFT) \cite{GM12}.
TDDFT embodies many concepts and formal exact results, but its core
is the 1-1 correspondence \cite{RG84} between time-dependent ... | {

Hard X-ray Modulation Telescope (HXMT) is a planned Chinese space X-ray

Since the discovery of a bow shock in the periphery of the bullet cluster 1E 0657-558 \citep{markevitch2002},
it has been well established that shock waves exist in and around galaxy clusters.
