INPhINIT 2020 Incoming Fellowship: "Resolving the molecular tori and outflows in the most luminous Seyferts in the local Universe."

Application deadline:

The Doctoral INPhINIT Incoming fellowship offers 3-year contracts for early-stage researchers of any nationality to carry out a PhD project in research centres accredited with the Spanish Seal of Excellence Severo Ochoa, María de Maeztu or Health Institute Carlos III, on STEM disciplines. Centro de Astrobiología (CSIC-INTA), Unidad de Excelencia “María de Maeztu”, offers the following PhD position: One of the most exciting discoveries in extragalactic astronomy is that the majority of massive galaxies in the Local Universe contain supermassive black holes at their centers. The properties of these black holes are related to those of their host galaxies revealing their close evolution. When material is accreted onto a massive black hole, large amounts of energy are released. The nuclear region then becomes extraordinarily luminous, sometimes even outshining the whole galaxy. During this process the galaxy is classified as an active galactic nuclei (AGN) and quasars are the most luminous examples in this class. The emerging picture for the central regions of active galaxies has an obscuring torus as the central structure in a gas flow cycle in which gas is brought in from the host galaxy disk (inflow) and then driven out by the AGN in a wind (outflow). The Galaxy Activity, Torus, and Outflows Survey (GATOS) collaboration aims to address fundamental questions of the life cycle of the AGN phenomenon in galaxies. The main tasks associated with this job include: (1) data reduction and analysis of the ALMA observations to produce fully reduced data cubes of the two transitions as well as continuum maps, (2) modelling the geometry (size, orientation, vertical extent) of the continuum and molecular gas emission probing the molecular dusty torus, (3) modelling of the CO(3-2) and HCO+(4-3) kinematics to identify signatures of molecular inflows and/or outflows on both nuclear and circumnuclear scales and comparison with ionized outflows traced by the IFU observations, and (4) detailed comparison with predictions from hydrodynamical simulations carried out by the GATOS theory and modelling team.
