Abstract

According to recent studies on galaxy formation, every galaxy forms within a dark matter halo. The study of how formation and growth of galaxies over time is connected to the growth of the halos in which they form is designated as halo-galaxy connection. The advent of large galaxy surveys as well as high-resolution cosmological simulations are providing new insight into the statistical relationship between galaxies and halos and its evolution. The objective of this Scientific Initiation project is to make the student acquainted with the basic tools and methods related to halo-galaxy connection, such as SAMs and multi-(LSS)tracer methods. Therefore she can contribute to solving key open questions about how galaxies and halos are connected, including understanding the correlations with secondary properties and the connection of these properties to galaxy clustering.
