Abstract: "In this talk Scherk-Schwarz compactifications of the recently developed duality covariant approach to supergravity are considered. According to this formalism the space-time gets extended to include U-duality symmetries in a manifest way. It is shown that Scherk-Schwarz reductions naturally reproduce structures of the scalar sector of gauged supergravities such as the embedding tensor, the gauge algebra and the scalar potential. The algebraic properties become related to geometry of the extended space."
The presentation will give an overview about the design of the LHC storage ring, summarising briefly the main parameters, the basic laypout of the machine and the operational experience that we could gain in Run1. The mini beta values that could be achieved and corresponding to that the luminosity will be explained, as well as the limits for the machine performance like beam beam effects observed in routine operation and in dedicated accelerator studies. Looking a bit into the future new aspects of the LHC operation will be discussed in the context of energy and luminosity increase after the present shut down. The planned 6.5 TeV operation in 2015 and beyond will pave the way to smaller beam dimensions and a natural increase of the expected luminosity of the machine.
A deeper look on thick discs using data from the Spitzer Survey of Stellar Structure in Galaxies (S4G)
Thick discs are disc-like components with a scale height larger than that of the classical discs. They are most easily detected in close to edge-on galaxies in which they appear as a roughly exponential excess of light which appears a few thin disc scale heights above the midplane. Their origin has been considered mysterious until recently and several formation theories have been proposed. Unveiling the origin of thick discs is important for understanding galaxy evolutionary processes.
I will review the results we obtained on thick discs using data from the S4G:
1) Thick discs are much more massive than previously thought. This advocates for an in situ origin of thick discs at high redshift and for them being a reservoir of missing baryons.
