   Abstract : The Hubble parameter H(z) is a measure of the expansion rate of the universe at redshift z. One method to determine it relies on inferring the slope of the redshift with respect to cosmic time, where galaxy ages can be used as a proxy for the latter. This method is used by Simon et al.

3. 2. Determination of depositional environment and luminescence dating of Pleistocene deposits in the Biely Váh valley, southern foothills of the Tatra Mountains, Slovakia

   University essay from Lunds universitet/Geologiska institutionen

   Author : Ingrid Bejarano Arias; [2020]
   Keywords : Luminescence dating; glacifluvial deposits; sedimentological analysis; High Tatra Mountains; IRSL dating.; Earth and Environmental Sciences;

   Abstract : The Tatra Mountains have had several glaciations during the Quaternary. The deposits located in the southern foothills were classified as glacifluvial, based on geomorphology, but its sediments have not been studied in detail. READ MORE
