Advancements in High Angular Resolution Astronomy: Insights from SALTO, SCExAO VAMPIRE, and BIFROST/Asgard Suite |
High angular resolution instrumentation is reshaping modern astronomy, enabling us to probe fine structural details of celestial objects with unprecedented clarity. This capability is vital for studying exoplanetary atmospheres, star formation regions, and the environment around supermassive Black Holes at the centre of galactic nuclei. By utilizing techniques such as adaptive optics and interferometry, we can overcome atmospheric distortions and achieve resolution levels far beyond traditional limits. Adaptive optics systems dynamically counteract atmospheric turbulence, while interferometric arrays combine telescopes to expand baseline and angular resolution. In this presentation, we will delve into three cutting-edge high-resolution systems: SALTO, an advanced adaptive optics system for medium-class telescope; SCExAO VAMPIRE, a high-contrast imaging instrument with innovative non-common path aberration correction at the Subaru Telescope; and BIFROST, a short-wavelength, high-spectral dispersion beam combination instrument in the Asgard visitor instrument Suite at the Very Large Telescope Interferometer (VLTI). Together, these instruments illustrate the forefront of astronomical observation, offering insights that are essential for the next generation of discoveries. |
