Cosmology vs. Physical Cosmology

[pierce15]

Is there a difference between cosmology and physical cosmology? The two have separate wikipedia pages which seem to say essentially the same thing. Also, cosmology is obviously a branch of physics, so is "physical" redundant?

 

[Chronos]

Physical cosmology is generally regarded as a subset of cosmology dealing with large scale structure and dynamics of the universe. It can also be regarded as dealing with the observable properties of the universe.
