Studying galaxy formation through Lyman alpha in emission and absorption
… formation is one of the central problems of Physical Cosmology. Neutral hydrogen plays an important role, linking the collapse of cooling gas into haloes with the formation of stars. Lyman alpha, hydrogen’s strongest spectral line, can directly probe neutral hydrogen in the high redshift …

Models of the Galaxy and the massive spectroscopic stellar survey RAVE
… between stellar Galactic astronomy and physical cosmology. In the second part of the thesis we use a sample of high-velocity halo stars from the RAVE data to estimate the Galactic escape speed and the virial mass of the Milky Way. In the course of this study cosmological simulations of …

Fundamental physics from observations of the early universe
… other large scale structure surveys will enable cosmology to answer some of the fundamental questions in physics. The linear perturbation theory may not be accurate enough to interpret the observations from Planck and future CMB experiments. Second order effects may in particular be important in …
