Cosmological simulations of structure formation

Le 19 décembre 2014 De 10h30 à 12h00 Benjamin L'HUILLIER Korea Institute for Advanced Study, Seoul Cosmological simulations have become a powerful tool to describe the non-linear regime of structure formation. After reviewing the main aspects of cosmological simulations, I...

Looking for the identity of the dark matter in our backyard

Le 15 décembre 2014 De 14h00 à 16h00 Carlos FRENK Institute for Computational Cosmology, University of Durham One of the most impressive advances in Physics in the past three decades is the development of the ``standard model of cosmology,'' LCDM (where L stands for...

The disc-spin-jet connection in stellar and supermassive black holes

Le 12 décembre 2014 De 10h30 à 12h00 Chris Done University of Durham, UK Black hole spin is difficult to measure as it leaves an imprint only close to the horizon, but it may be required to produce most dramatic relativistic jets seen in the flat spectrum radio quasars (FRII)...

The Role of Spiral Arms on the Star-Formation Process

Le 28 novembre 2014 De 10h30 à 12h00 David EDEN Observatoire astronomique de Strasbourg The role of spiral arms in the star-formation process is unclear but the production of a quantitative relationship between changes in the star-formation efficiency, and stellar initial mass...

Understanding the Milky Way with Hamiltonian Mechanics

Le 21 novembre 2014 De 10h30 à 12h00 Giacomo MONARI Observatoire astronomique de Strasbourg I present a short summary of Hamiltonian Mechanics and how it can be used to understand the structural and kinematic properties of the Milky Way. I start with the most relevant basic...

Towards the next generation of empirical galaxy formation models

Le 20 novembre 2014 De 12h30 à 13h30 Benjamin MOSTER Cambridge University The field of galaxy formation is on the cusp of a tide of new data. To understand these in the context of an evolutionary picture, we need models that interpret the observed trends. Hydrodynamical...

Data Mining of the Large-Scale Structure from Galaxy Surveys

Le 13 novembre 2014 De 11h00 à 12h00 Francesco KITAURA AIP Potsdam The present-day mass density field contains information about the fundamental pillars of cosmology. It is a mixture and cross-talk between the primordial density fluctuations, the law of gravity and the value...

Measuring relativistic effects in galaxies and clusters

Le 10 novembre 2014 De 10h00 à 11h00 HongSheng ZHAO University of St Andrews Relativistic effects are generally second order or higher in galaxies and clusters. Here I discuss how modern instrumentation and large data are making such measurements feasible. These measurements...
