This thesis focus on understanding the physical properties of galaxies at redshifts 2.3 < z < 3.3, a time period called Cosmic Noon when galaxies were actively forming stars and evolving rapidly. The work involves the study of different galaxy populations, from young Lyα emitters (LAEs) and Lyman break galaxies (LBGs), to more evolved, and very

En las últimas décadas, la comunidad astrofı́sica ha realizado un gran esfuerzo para entender la formación y evolución de las galaxias. A pesar de la gran cantidad de estudios teóricos en este campo, se requieren trabajos observacionales más numerosos y detallados para testear estos modelos. En galaxias cercanas, varios estudios observacionales han

The almogaren (rock-cut sanctuary) of Risco Caído was discovered in 1996 in the Canary island of Gran Canaria. It is a paradigmatic example of a complex where light and shadow effects of an astronomical character have been found within the recent archaeological discoveries of a religious and ritual character in the Canaries. The main artificially

This paper describes the observations and the first data release (DR1) of the ESO public spectroscopic survey "VANDELS, a deep VIMOS survey of the CANDELS CDFS and UDS fields". The main targets of VANDELS are star-forming galaxies at redshift 2.4 z 5.5, an epoch when the Universe had not yet reached 20% of its current age, and massive passive
