INPhINIT Incoming PhD: " The role of angular momentum in galaxy evolution: A study of neutral gas in isolated galaxies with Square Kilometre Array pathfinders"
The Doctoral Fellowship INPhINIT Incoming Programme is devoted to attract young researchers willing to carry out their PhD project in research centres accredited with the Spanish Seal of Excellence Severo Ochoa, María de Maeztu or Health Institute Carlos III and Portuguese units accredited as “excellent” according to the evaluation of the Fundação de Ciência e Tecnologia.
The proposed PhD project aims to define the role of angular momentum in regulating the HI content of isolated galaxies, and so in galaxy evolution (fully aligned with SKA
Prioritized Goals). In order to answer this question, the applicant will use existing radiointerferometric observations with SKA pathfinders, the VLA (Very Large Array) and
GMRT (Giant Metrewave Radio Telescope), from the 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 modelling software
(e.g. GUIpsy, TiRiFiC and 3D Barolo). 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 expected theoretical relation. Any
deviations from this relation must then be investigated to understand both their
cause and influence on the subsequent evolution of the galaxies.
