Técnicas experimentales para el estudio de galaxias distantes con instrumentación puntera de GTC

Resumen

During the last decades, observational astronomy has undergone a revolution due both to the construction of ever-larger telescopes that allow us to reach ever-distant and fainter objects, and to the technological breakthroughs that have allowed the design of very preciseand powerful instruments. Generally, state-of-the-art instruments enhance the performance and capabilities of large telescopes by providing novel observing modes and improvements such as better spatial/spectral resolution, higher sensitivity, wider field of view, wider wavelength range coverage, or the possibility of spectroscopically observing multiple astronomical sources at the same time. In this context, the Gran Telescopio Canarias (GTC), located in the Roque de los Muchachos Observatory, is currently the largest optical-infrared telescope in the world. Its privileged location and its primary segmented mirror of 10.4 meters in diameter make it one of the most powerful and competitive astronomical facilities. The GTC is equipped with cutting-edge scientific instruments that together offer a wide variety of observing modes. This combination of large collecting area and advanced instrumentation is key to addressing the current astronomical challenges, including the study of the early Universe and the impact of galaxy evolution through cosmic time. Extragalactic astronomy tries to answer open questions on galaxy evolution by detecting distant sources and studying their formation processes, their interaction with the environment, and their physical and kinematic properties among others...
