The European Solar Telescope (EST) aims to become the most ambitious ground-based solar telescope in Europe. This paper summaries the planned architecture, software practices adopted at the moment for the development environment and future lines. EST has adopted a mix of proven software from existing telescopes that are suited to the telescope

Given their low surface brightness, it is hard to determine high-quality spectra of dwarf galaxies outside the Local Group, where it is not possible to study the individual stars. Although several studies exist that use absorption line lengths to study the stellar populations of dwarf galaxies, studies of the Star Formation Histories in these

At the edge of galaxies, in the lowest surface brightness regimes, lies the boundary where gas can collapse to form new stars. These regions remain largely unexplored due to the lack of very deep images that allow us to characterize the star-forming clumps at the edge of the discs. In this sense, we do not know whether stellar activity in these

We present an extension to a Sunyaev-Zel'dovich Effect (SZE) selected cluster catalogue based on observations from the South Pole Telescope (SPT); this catalogue extends to lower signal to noise than the previous SPT-SZ catalogue and therefore includes lower mass clusters. Optically derived redshifts, centres, richnesses, and morphological

Stellar modelling is crucial for understanding the structure and age of stars. The accuracy of a stellar model is limited by the constraints from observations and the theory behind the physical processes. Gravitationally bound stars of a binary system provide an excellent opportunity for a combined study, which provides strong constraints on the

We propose and discuss a new experimental approach to measure the centroid shift induced by gravitational microlensing in the images of lensed quasars (astrometric microlensing). Our strategy is based on taking the photocenter of a region in the quasar large enough as to be insensitive to microlensing as reference to measure the centroid
