DESCRIPTION:Speakers: Amrit Sedain (University of Potsdam)\nProlate rotati
 on in galaxies (rotation around the major axis) is a rare phenomenon in th
 e Universe. The effect has been exclusively attributed to past major merge
 rs and thus studies of prolate-rotating systems can help us better underst
 and the hierarchical process of galaxy evolution. Dynamical studies of suc
 h galaxies is important to find their gravitational potential profile\, to
 tal mass\, and dark matter fraction. Recently\, it has been shown from cos
 mological simulation that it is possible to form a prolate-rotating dwarf 
 galaxy following a dwarf-dwarf merger event. The simulation also shows tha
 t the unusual prolate rotation can be time enduring. In this particular ex
 ample the galaxy started rotating around its major axis about 7.4 Gyr ago 
 and it is still continuing at the present time. In this project\, we use m
 ock observations of the hydrodynamically simulated galaxy to fit various s
 tages of its evolution with Jeans dynamical models. The Jeans model succes
 sfully fits the early oblate state and also for late prolate stage of simu
 lated galaxy\, prior the major merger event\, recovering the anisotropy\, 
 mass density distribution\, velocity dispersion\, and rotation of the simu
 lated galaxy. This master thesis project is an important connecting link b
 etween cosmological simulations and real observational data\, as many prol
 ate rotation galaxies are being discovered.\n\nhttps://iaus379.aip.de/even
