VIMOS is visible multi-object spectrometer operating on the VLT. The high multiplex of the VLT visible imager and multi object/integral-field spectrometer...

Measuring the Aerosol Optical Depth (AOD) is of particular importance in monitoring aerosol contributions to global radiative forcing and air quality. Most...

How galaxies form and evolve remains one of the cornerstone questions in our understanding of the universe on grand scales. While much progress has been made by...

The Vlasov-Poisson system is the mean field limit of the classical N-body problem as N goes to infinity. First considered in plasma physics, it has been also...

Chemical abundances derived using emission-line spectra in ionized gaseous nebulae are between the most useful properties that can be derived to understand the...

An exciting series of changes are taking place at the venerable WHT and INT on La Palma. WEAVE, the next generation multi-fibre spectrograph is being completed...

I will make an overview of the classical pulsating variable stars (i.e. SX Phoenicis, RR Lyrae, Anomalous Cepheids, Classical Cepheids) in our Local Group and...

Jurčák criterion states that umbra-penumbra boundaries are defined by a constant vertical magnetic field in stable sunspots. In this seminar I will talk about...

Understanding the atmospheric and evolutive properties of very low mass stars, brown dwarfs, and gas giant exoplanets have been important challenges for...
