En esta charla se dará a conocer la comisión de Medioambiente y Sostenibilidad del IAC y el trabajo que se está llevando a cabo. El IAC quiere ser parte activa de las soluciones para alcanzar los objetivos que marca Europa para los futuros años. Se expondrán algunos números relacionados con nuestro gasto y consumo en el IAC que nos pueden hacer

In cosmology, it is customary to convert observed redshifts into distances in order to study the large scale distribution of matter probes like galaxies and quasars, and to obtain cosmological constraints thereof. In this talk, I describe a new approach which bypasses such conversion and studies the "field of redshifts" as a new cosmological

The next decade will see a deluge of new cosmological data that will enable us to accurately map out the distribution of matter in the local Universe, image billions of stars and galaxies to unprecedented precision, and create high-resolution maps of the Milky Way. Signatures of new physics as well as astrophysical processes of interest may be
