General
Nuestro proyecto puede dividirse en dos líneas principales de investigación. En primer lugar, el estudio de los vientos producidos por cuásares luminosos oscurecidos y del impacto que estos tienen en sus galaxias anfitrionas (retroalimentación del AGN). Para ello hemos obtenido observaciones infrarrojas y ópticas con los instrumentos del Gran Telescopio CANARIAS (GTC) CanariCam, EMIR y MEGARA, así como datos de ALMA en el rango milimétrico. Parte de esta investigación la realizamos en el marco de la Innovative Training Network BID4BEST, del programa H2020. Nuestro grupo está también fuertemente involucrado en el consorcio internacional GATOS (Galactic Activity, Torus and Outflow Survey), creado con el objetivo de conseguir tiempo en el JWST y ALMA para caracterizar el ciclo del gas y el material que oscurece el núcleo de galaxias activas cercanas. En segundo lugar, nuestra actividad se centra en la aplicación de la espectroscopia de campo integral al estudio de objetos extensos tales como galaxias con formación estelar o galaxias activas para investigar el encendido de ambos fenómenos. Asimismo, contribuimos al desarrollo de nuevos instrumentos y técnicas de análisis de datos relacionadas con la espectroscopia 3D. En particular, participamos en el desarrollo del espectrógrafo de campo integral de alta resolución HARMONI, uno de los instrumentos de primera luz del Extremely Large Telescope de la ESO.

Publicación de una letter en MNRAS donde estudiamos la conexión entre los vientos de gas ionizado y las poblaciones estelares jóvenes en el cuásar de tipo 2 Mrk 34 (Bessiere & Ramos Almeida 2022). Encontramos evidencias de retroalimentación positiva y negativa en distintas partes de la misma galaxia, inducidas por el viento. Este trabajo, parte del proyecto QSOFEED, abre una nueva ventana a la investigación del impacto directo de la actividad nuclear en la formación estelar en galaxias.

QSOFEED: Relationship between star formation and active galactic nuclei feedbackContext. Large-scale cosmological simulations suggest that feedback from active galactic nuclei (AGN) plays a crucial role in galaxy evolution. More specifically, outflows are one of the mechanisms by which the accretion energy of the AGN is transferred to the interstellar medium (ISM), heating and driving out gas and impacting star formation (SF)Bessiere, P.
