The standard cosmological model, in conjunction with the more recent observations, indicate that the Universe is composed of 4% radiation and barionic matter, and 96% of unknown components: cold dark matter, until now not directly detected, but necessary for the formation of structure and energy dark, responsible for the accelerated expansion of the Universe. There are open questions that modern cosmology seeks to answer: What is the nature of dark matter? What is the nature of the dark energy that dominates the Universe? What happened in the first moments of the Universe and what is the physics behind this phenomenon? These questions have inspired ambitious research programs to answer them. At IFUNAM, dark matter and energy are studied from the theoretical-phenomenological and experimental-observational perspectives. Participate in two dark energy experiments: the Sloan Digital Sky Survey IV (SDSS-IV) / Extended Baryon Oscillation Spectroscopic Survey (eBOSS) and the Dark Energy Spectroscopic Instrument (DESI)
String theory (TC) seeks, among others, to answer the questions that cosmology and particle physics study. In particular, it proposes that the scenarios based on compactifications of 6 of the 10 dimensions, typical of CT, lead to fields whose dynamics and properties could explain the cosmological inflation, the origin of dark matter and energy, and the qualities of the standard particle pattern. At IFUNAM, research focuses on the study of the properties of fields and their dynamics in string models to show whether this hypothesis is correct.
