An hi study of the nearby dwarf galaxy ic 4710

Mothogoane, Getrude Thando January 2021 (has links)
>Magister Scientiae - MSc / This work aims to study the dark matter content of the nearby (7.38 Mpc) dwarf galaxy IC 4710 using the HI line observations from the Australia Telescope Compact Array (ATCA). We produce the rst interferometric maps of the galaxy HI distribution and dynamics and use these maps to measure important quantities such as total HI mass, velocity width, and size. We create a dynamical model of the galaxy using a three-dimensional modeling technique. The rotation curve was obtained by tting a 3D tilted ring model to the HI data cube of galaxy IC 4710. The dynamical modeling of IC 4710 is being done for the rst time. We compare the model to the data cube to check for accuracy and found that they are in good agreement; this shows that the results are reliable. The obtained rotation curve is rising steeply until it reaches the maximum rotation velocity of 24.6 km s􀀀1 at a radius of 100 arcsec.

Nové možnosti experimentálního zajištění základů přírodovědného vzdělávání / New possibilities of providing basic natural science education through experiments

Köhlerová, Veronika January 2013 (has links)
TITLE: New possibilities of providing basic natural science education through experiments AUTHOR: Mgr. Veronika Köhlerová DEPARTMENT: Department of Chemistry and Chemistry Education SUPERVISOR: Prof. RNDr. Pavel Beneš, CSc. ABSTRACT: The thesis stems from the basic need to support and develop natural science education. Based on didactic, technical-economic and ergonomic requirements, a teaching tools kit has been created, which facilitates 100 natural science experiments. The kit includes a methodological manual; further methodological support is also provided on the webpage of the kit's manufacturer. To complement the kit, a concept of an optional teacher training course Natural Science Experiments for Preschools and Primary Schools has been created. The course will take place at the Pedagogical Faculty of Charles University in the school year 2013/2014. During the course of the thesis, didactic research methods were used to choose, process, test, organize, and optimise educational experiments. The pedagogical methods used included questionnaires and expert testimonials. The thesis provides a substantial response to the current educational needs in the field of natural science pre-literacy already at preschools and natural science literacy at primary schools. KEYWORDS: science experiment, natural science...
