The star counting technique by the PAndAS survey reveals that M33 is undergoing a tidal interaction with its massive neighbor, M31. Due to this interaction, the stellar halo of M33 shows faint tidal features. These features are only visible at extremely low surface brightness levels (i.e. >30 mag/arcsec^2). For this reason, M33 is a perfect test

The High Angular Resolution Monolithic Optical and Near-infrared Integral field spectrograph (HARMONI) is a first generation instrument designed for the Extremely Large Telescope (ELT). HARMONI offers operational versatility, enabling both seeing-limited (NOAO) operation and compensation for atmospheric optical turbulence using two systems: Single

The European Solar Telescope (EST) will be the biggest solar telescope in Europe and it is currently concluding its preliminary design that includes adaptive optics from its first light. In this phase of the project, the feasibility of the project is demonstrated and the design must meet the requirements after having mitigated the major risks. The
