Description
One of the instruments developed for the Advanced Technology Solar Telescope (ATST) site survey is a non-redundant array of six scintillometers known as a ShaBaR (SHAdow BAnd Ranging) system, developed by J. Beckers. The ShaBaR provides an estimate of Cn2(h), the turbulence structure function, in the Earth's atmosphere. We can use the estimate of Cn2(h) to infer the value of r0, the Fried parameter, at any height above the ground up to the maximum range of the ShaBaR. In this poster, we present two methods of extracting the estimates by 1) inverting the data via a kernel function derived from the theory of atmospheric turbulence, and 2) assuming a modified Hufnagel-Valley model of Cn2(h). We also show a series of simulations that has been produced and used to test the accuracy and precision of the methods.

    The luminosity functions of an homogeneous sample of 50 young nearby open clusters
    Open clusters are groups of coeval stars sharing properties such as distance and metallicity, and they are key to understanding stellar evolution. We shed light on the evolution of open clusters with a special focus on the universality of the luminosity function. We applied an upgraded version of the convergent point technique on about 50 open

    Gas Flows in the Central Regions of NGC 4593 with Muse
    Gas flows into the centres of galaxies form an important ingredient to the formation, growth and evolution of galaxies. The process of gas falling into the central supermassive black hole (SMBH) can lead to high levels of non-stellar emission which results in an active galactic nucleus (AGN). However, the details of how such gas flows reach the

    The effect of local and large scale environment on star formation histories in galaxies
    The environment of galaxies plays a key role in their evolution. The availability of large extragalactic surveys makes it possible to place a galaxy not only in its immediate environment, but also in its position within the large-scale structure of the universe. Within this context, we investigate how the local environment influences the star
