Achernar Can be a Differential Rotator
We take advantage of interferometric measurements of Achernar to inquire on its internal rotational law. The reinterpretation of interferome-tric data

Age determination of the nuclear stellar population of Active Galactic Nuclei using Locally Weighted Regression
We present a new technique to segregate old and young stellar populations in galactic spectra using machine learning methods. We
