Phylogenetic signal in spectroscopic surveys. One of the main motivations to generate large spectroscopic surveys of Milky Way stars is to study the structure, formation and evolution of the Milky Way. There are several spectroscopic surveys available to the community today. We are very curious to analyze trees from such datasets and discover the past […]
What do phylogenetic trees tell us about the merging history of the Milky Way? Building trees from stars living in the galactic halo might provide us with novel and interesting insights about the merging history of the Milky Way. We choose the galactic halo because its stellar content is made of stars of different origins
Cosmic phylogeny from first principles. Fossil data is extremely imperfect. In addition to limited and uncertain observables in the fossil data (in our case, stellar abundances), it lacks a complete coverage in the timeframe which is being investigated (in our case, from the big bang to the present). This makes it very difficult, if not
