Further insight toward the complex association and dissociation events of macromolecules requires the development of a spectroscopic technique that can track individual components, or building blocks of these macromolecules, and the complexes which they form, in real time. Three-color fluorescence cross-correlation spectroscopy (3C-FCCS) has been shown to track assemblies of three spectrally la...

The very high spatial resolution provided by Adaptive Optics assisted spectroscopic observations at 8m-class telescopes (e.g. with SINFONI at the VLT) will allow to greatly increase the number of direct black hole (BH) mass measurements which is currently very small. This is a fundamental step to investigate the tight link between galaxy evolution and BH growth, revealed by the existing scaling...

The spectroscopic characterization of individual nanostructures is of fundamental importance to understanding a broad range of physical and chemical processes. One general and powerful technique that addresses this aim is dark-field microscopy, with which the scattered light from an individual structure can be analyzed with minimal background noise. We present the spectroscopic analysis of indi...

We present spectroscopic observations of 21 faint arcs seen in the HST image of the cluster Abell 2218 for which redshifts have been predicted using a lensing inversion technique based on the cluster mass model discussed by Kneib et al. (1996) 1. This mass model is constrained by multiply-imaged sources seen in the HST image, 2 of which have known redshifts. Preliminary results indicate that th...

In life sciences, diastereomeric chiral molecule/chiral receptor complexes are held together by a different combination of intermolecular forces and are therefore endowed with different stability and reactivity. Determination of these forces, which are normally affected in the condensed phase by solvent and supramolecular interactions, can be accomplished through the generation of diastereomeri...
