    Deriving precise parameters for cool solar-type stars. Optimizing the iron line list
    Context. Temperature, surface gravity, and metallicitity are basic stellar atmospheric parameters necessary to characterize a star. There are several methods to...

    DES Y3 cosmic shear down to small scales: Constraints on cosmology and baryons
    We present the first analysis of cosmic shear measured in DES Y3 that employs the entire range of angular scales in the data. To achieve this, we built upon...
