"Physical characterization of brown dwarfs"

Elena Manjavacas (MPIA Heidelberg)

Abstract
Brown dwarfs are substellar objects (M<75MJup) which do are not able to sustain H burning. During their evolution, they cool down, changing their effective temperature and their spectral types, and it is difficult to constrain masses and ages for brown dwarfs. Determining the initial mass function and the evolution for these substellar objects is therefore a challenging problem. During my PhD I addressed the problem of brown dwarf characterization in three different approaches: determining parallaxes of several T brown dwarfs, medium resolution VLT/ISAAC spectroscopy of young M-L brown dwarfs and searching for brown dwarf binaries using VLT/X-Shooter spectroscopy.

"Modelling Galaxies within state-of-the-art Cosmological Simulations"

Violeta Gonzalez-Perez (University of Durham)

Abstract
Galaxies are thought to form within haloes of dark matter, whose gravity allows the galaxies to exist. The formation and evolution of galaxies is affected by a multitude of other processes besides gravity and computational modelling is the only way we can attempt to understand all these processes. In this work we present a new development of the GALFORM semi-analytical model of galaxy formation and evolution, which exploits a Millennium Simulation-class N-body run performed with the Wilkinson Microwave Anisotropy Probe 7 cosmology. We use this new model to study the impact of the choice of stellar population synthesis (SPS) model on the predicted evolution of the galaxy luminosity function. Besides this model, we have generated a new GALFORM flavour constructed from merger trees derived from EAGLE, a hydrodynamical simulation. We compare results from both GALFORM and EAGLE.
