What exactly is a resonance state?

My understanding so far is that a resonant state appears as a large spike in the DOS of a material due to an adsorbed impurity or vacancy in the lattice and that they act as quasilocalized states, but I can't seem to find a source which describes exactly what one is.

Why do they manifest as sharp peaks when you look at the DOS? I guess this is why they have the name resonance states,
