Descripción del proyecto
Nuevos conocimientos sobre los flujos de gas producidos por los agujeros negros masivos
Los agujeros negros masivos se encuentran en el centro de las galaxias y liberan una cantidad extraordinaria de energía durante su fase de acreción. Estas cantidades de energía desencadenan la formación de flujos de gas que pueden influir considerablemente en la evolución de la galaxia anfitriona. Sin embargo, a pesar del notable trabajo teórico y experimental realizado para estudiar la dinámica de dichos flujos, sigue sin saberse cómo afectan exactamente a la formación y evolución de las galaxias. El equipo del proyecto financiado con fondos europeos WINGS ahondará en esta cuestión. En WINGS se llevará a cabo el mayor estudio de alta resolución espacial de los flujos multifásicos combinando las observaciones del telescopio espacial James Webb de la NASA, el Atacama Large Millimetre/Submillimetre Array y el Telescopio Muy Grande del Observatorio Europeo Austral.
Objetivo
Massive black holes (BHs) reside at the center of galaxies and release an extraordinary amount of energy during their accretion phase. Such energy drives galaxy-scale gas outflows that can significantly influence the evolution of the host galaxy. Despite the remarkable theoretical and observational progress in quantifying the energetics and dynamics of such outflows, establishing their role during the formation and evolution of galaxies remains a long-standing problem in modern astrophysics. WINGS is designed to finally settle whether outflows driven by BHs are able to shape galaxies and their environment or not. To achieve this goal, we will build up a novel observational and theoretical framework that investigates the role of outflows in the early Universe, when BHs and galaxies are growing at the highest rates and outflows are expected to be more common and powerful, leaving a prominent mark on galaxy evolution. Thanks to the PI, WINGS will have access to several key observing programs carried out with ALMA and VLT as well as the guaranteed-time observer (GTO) program (~900 hours) with the NIRSpec spectrograph on board the soon-to-launch JWST. By exploiting both observations of local outflows and zoom-in simulations, we will develop a 3D kinematic outflow model that will be an asset in (i) interpreting existing high-redshift data and upcoming JWST observations, (ii) characterizing for the first time outflow properties across cosmic time (up to z~9), and (iii) identifying feedback signatures in the interstellar and circumgalactic medium properties. The combination of JWST, ALMA, and VLT observations will enable WINGS to assemble the largest high-spatial resolution survey of multi-phase outflows. The support from the ERC will be crucial to assemble a unique team mixing the observation-oriented and theory-oriented approach, as a joint effort of observations and simulations is the key to make a major breakthrough in understanding outflows driven by BHs.
