"How galaxies and the large-scale structures in which they are embedded form is a fundamental question in extra-galactic astronomy. It is an area that has seen tremendous progress, but is still constantly challenged by ever-improving observational data. This course introduces you to this fascinating subject and the underlying physics, starting from how small density perturbations grow into dark matter haloes, to how baryons cool and form the galaxy population we observe today.\n\nPhysical concepts are derived from basic principles where possible. The emphasis is on intuitive rather than mathematically rigorous derivations.\n\nTopics that will be covered include:\n\nLinear growth of density perturbations\nFree streaming\nTransfer functions and the matter power spectrum\nNon-linear spherical collapse\nJeans smoothing\nRadiation drag\nStatistical cosmological principle\nClustering and biasing\nHalo mass functions and Press-Schechter theory\nScaling laws and virial relations\nCosmic web\nRedshift-space distortions\nRadiative cooling and its importance\nAngular momentum and its influence\nReionization\nThe Gunn-Peterson effect\nThe thermal history of the intergalactic medium\nFeedback processes\nHalo models, semi-empirical models, and simulations\n\nOutcome:\nUpon completion of this course you will be able to explain how (we think that) large-scale structures and galaxies form and evolve and you will be able to carry out calculations of the formation of structures in the universe.\r\n\r\nUpon completion of the course you will be able to:\r\n\r\nCompute the growth of density fluctuations\r\nCompute the shape of the matter power spectrum\r\nExplain the morphology of the cosmic web\r\nExplain redshift-space distortions\r\nExplain galaxy biasing and clustering\r\nCompute halo mass functions using Press-Schechter theory\r\nCompute galaxy and halo scaling relations\r\nUnderstand radiative cooling processes\r\nEstimate the effect of radiative cooling on galaxy formation\r\nEstimate the effect of angular momentum on galaxy formation\r\nModel the process of reionization\r\nCompute the thermal history of the intergalactic medium\r\nCompute Gunn-Peterson absorption\r\nUnderstand the basics of feedback processes in galaxy formation\r\nUnderstand the basics of halo models, semi-empirical models and simulations of galaxy formation" . .

"In the master’s specialisation Astronomy and Data Science you focus on development and application of new data-mining technologies, fully embracing modern astronomy as a data rich science. You combine the research curriculum in Astronomy with in-depth training in Computer Science.\n\nThe Astronomy and Data Science master’s programme is built on world-class computational astrophysics research as well as hightech industry expertise. It covers a wide range of research areas studying complex astronomical phenomena, including radiative transfer, computation of dynamical internal galaxy structures and hydrodynamical modeling of galaxy formation and evolution of the intergalactic medium.\n\nThis two-year Astronomy and Data Sicence programme uniquely combines advanced Astronomy courses of the Leiden Observatory and relevant courses from the Computer Science master’s programme of the Leiden Institute of Advanced Computer Science including advanced data mining and neural networks. To this end, the Leiden Observatory offers sophisticated computational facilities ranging from local computer clusters to high-performance systems at national and international computing centers.\n\nOutcome:\nDuring the programme, you learn to perform academically sound research and evaluate scientific information independently and critically. Without exception, you actively participate in current research within the institute and are individually supervised by our international scientific staff. Students with a Leiden degree in Astronomy become strong communicators and collaborators and can easily operate in an international setting. You will acquire extensive astronomical research experience and highly advanced analytical and problem solving skills."@en . . . . . . "2"@en . "FALSE" . . "Master"@en . "Thesis" . "2314.00" .
