We present new speckle measurements of the position of Linus, the satellite of the asteroid (22) Kalliope, obtained at the 1 m Centre Pédagogique Planètes et Univers-Epsilon telescope on the Plateau de Calern, France. Observations were made in the visible domain with the speckle camera Pupil Interferometry Speckle camera and COronagraph. We...

Adaptive optics is challenging for smaller telescopes (0.5∼2m) due to the small isoplanatic angle, small subperatures and high correction speeds needed at visible wavelengths, requiring bright stars for guiding and thus severely limiting the sky coverage. To enable large sky coverage we can correct the turbulence which is common to the entire...

Intensity Interferometry offers an interesting path forward for astronomical interferometry at very long baselines and at short wavelengths, all leading to extremely high angular resolution. Single photon counting detectors (and associated correlator technology) has evolved to allow a sensitivity gain of two orders of magnitude since the...
