You are 100% wrong. Several Nobel prizes have been awarded for seminal results in cosmology, like observation of the cosmic microwave background and the discovery of accelerated metric expansion.
I'm not sure what the other thing you're referring to is, but I used to go to some of Joe Taylor's seminars: he was an astronomer, not a cosmologist. Cosmologists are people who publish papers that can't be tested by people like Penzias, Wilson and Taylor.
Once again you are wrong. Mather, Smoot, Perlmutter, and Riess are all cosmologists. Their Nobel prizes were awarded for results in cosmology.
Your idiosyncratic redefinition of the word "cosmology" is completely at odds with how the word is used in the physics community.
