3D cosmology from massive optical redshift surveys
Prof Jean-Paul Kneib (EPFL)
In the last 40 years, astronomers have charted the 3D position of galaxies in the Universe. With the recent Sloan Digital Sky Survey (SDSS) and the recent Dark Energy Spectroscopic Instrument (DESI) survey, a much clearer picture is arising of the matter distribution across the Universe. These measurements confirm the Lambda-CDM cosmology model even though some tension in the model still exists, and need to be understood.
I will give a summary of the recent progress and understanding, as well as give an outlook on future projects. In particular, I will present the required instrumental developments needed particularly in robotics to make the next-generation spectroscopic surveys possible.
