Improve the dark matter density field mapping using galaxy luminosity

Sebastien Fromenteau (ICF-UNAM)

RESUMEN: While the large scale structures formation is dominated by CDM field evolution, we generally have only access to baryonic tracer like galaxies. The usual method is to link the galaxy distribution to the CDM field using a linear bias. We propose to use a luminosity based methodology in order improve this mapping in order enhance the galaxy-CDM connexion using different galaxy tracers. One specific goal is to incorporate this study on the reconstruction algorithm for the future multi-tracer analysis.
