This project studies the environment of super-massive black holes that are actively accreting matter. Our specific objectives are to investigate the nuclear activity, torus and outflows of nearby active galaxies by studying molecular and ionised gas and dust on physical scales of tens of parsecs to several kiloparsecs in galaxies. For this we are using observations with the best angular resolution in the optical, infrared and (sub)millimetre obtained with the HST, ALMA, VLT, GTC and in the future with the JWST. In addition, our team develops radiative transfer models and numerical simulations of the torus and disc-wind dynamics for comparison with observations.

Image of the centre of one of the galaxies studied as part of the GATOS project: NGC 5643. It shows the central kilo-parsecs of the galaxy where we can see the presence of cold molecular gas (in reddish colours) in the form of a nuclear disc and rotating spiral arms, as well as large amounts of ionised gas (in blue and orange colours) being ejected on both sides of the galaxy. The nuclear disc detected by ALMA is a few tens of parsecs across and is not only rotating, but also expanding in its equatorial direction. Credit: ESO/A. Alonso Herrero et al.; ALMA (ESO/NAOJ/NRAO)
