The haloes of bright satellite galaxies in a warm dark matter universe

Alexey Boyarsky, Oleg Ruchayskiy, Jie Wang

High-resolution N-body simulations of galactic cold dark matter haloes indicate that we should expect to find a few satellite galaxies around the Milky Way whose haloes have a maximum circular velocity in excess of 40 km s-1. Yet, with the exception of the ...

Enhancing the light-matter interaction using slow light: towards the concept of dense light

Luc Thévenaz, Sang Hoon Chin, Isabelle Dicaire

A couple of experiments are here presented to clarify the impact of slow light on light-matter interaction. The experiments are designed, so that the process generating slow light and the probed light-matter interaction only present a marginal cross-effect ...

Manganese evolution in Omega Centauri: a clue to the cluster formation mechanisms?

We model the evolution of manganese relative to iron in the progenitor system of the globular cluster Omega Centauri by means of a self-consistent chemical evolution model. We use stellar yields that already reproduce the measurements of [Mn/Fe] versus [Fe ...

Dwarf Galaxies and Galaxy Halos

Martin Tafelmeyer

The various projects presented in this thesis contribute to the expansion of our knowledge and understanding of the fundamental processes involved in the formation of a galaxy and its stellar populations. For this purpose, two different techniques are appl ...

Cosmic Evolution Of Virial And Stellar Mass In Massive Early-Type Galaxies

We measure the average mass properties of a sample of 41 strong gravitational lenses at moderate redshift (z similar to 0.4-0.9) and present the lens redshift for six of these galaxies for the first time. Using the techniques of strong and weak gravitation ...

STAGES: the Space Telescope A901/2 Galaxy Evolution Survey

Yifei Guo

We present an overview of the Space Telescope A901/2 Galaxy Evolution Survey (STAGES). STAGES is a multiwavelength project designed to probe physical drivers of galaxy evolution across a wide range of environments and luminosity. A complex multicluster sys ...

The kinematic status and mass content of the sculptor dwarf spheroidal galaxy

Pascale Jablonka

We present VLT FLAMES spectroscopic observations (R similar to 6500) in the Ca II triplet region for 470 probable kinematic members of the Sculptor (Scl) dwarf spheroidal galaxy. The accurate velocities (+/- 2 km s(-1)) and large area coverage of Scl allow ...
