The proposed PhD project aims to define the role of angular momentum in key aspects of galaxy evolution (fully aligned with SKA Prioritized Goals), by paying a special attention to a careful definition of the environment of the target sample and its associated characteristics. The applicant will use existing radiointerferometric observations with SKA pathfinders, the VLA (Very Large Array) and GMRT (Giant Metrewave Radio Telescope), from AMIGA database.

In collaboration with experts within the AMIGA team the candidate will
• Reduce the VLA and GMRT data using the latest software and algorithms, within the framework of IAA SRC precursor activities.
• Model the kinematics of the galaxies using both 2D and 3D state of the art modelling software. The resulting models will be compared using 3D visualisation tools such as SlicerAstro and X3D.
• Calculate the total angular momentum together with the stellar masses using optical and infrared data from both AMIGA’s own observations and ancillary data from other surveys.
• Once the total angular momentum has been calculated the global stability of the galaxies will be contrasted with the theoretical predictions. Any deviations must then be investigated to understand both their cause and influence on the subsequent evolution of the galaxies.

There will also be highly beneficial opportunities for the candidate to expand the sample by leading proposals as PrincipaI Investigator, e.g by expanding the parameter space to
lower mass galaxies by applying for additional HI observations with the recently upgraded GMRT. S/he would collaborate with teams in other SKA member countries, such as South Africa, Australia or the Netherlands, with which AMIGA has established collaborations. In addition, s/he will work following Open Science principles, an area in which AMIGA team plays a key role at an international level and an area that is increasingly recognised as essential in scientific careers.
