I started my PhD with the International Max Planck Research School in Garching in September 2009. My supervisor is Prof. Jochen Weller and my research topic is Cosmological constraints from non-linear large scale structure.

Warm Dark Matter - If dark matter particles are relatively light (mass of the order of a few keV), then they may be able to remain at relativistic speeds in the early universe long enough to erase significantly large primordial density perturbations - this is called free-streaming. The signature of this smoothing depends on the mass of the particle as well as on whether all of dark matter consists of such particles. Such a signature may be observable today, in the statistics of the distribution of large scale structure on up to galaxy-sized scales.

   

Cosmic Shear - The cumulative weak gravitational lensing of the images of very distant galaxies by all intervening dark matter structures is a very promising probe of the statistics of the distribution of all matter in the universe. Cosmic shear as a probe has the advantage of not requiring the assumption of how luminous and dark matter are coupled in cosmic structures.

   

Early Dark Energy - If the current accelerated expansion of the universe is caused by a scalar field with a time-varying equation of state (quintessence), it may be that unlike in ΛCDM, a significant fraction of the energy density in the early universe is contributed by Dark Energy. The presence of Dark Energy in the early universe may be detectable due to its impact on the geometry of the universe at those times. An excellent standard rod for such a measurement is the signature of the acoustic oscillations of the baryon-photon fluid in the early universe, because it can be straightforwardly predicted from theory.
