Using kilometric arrays of air Cherenkov telescopes at short wavelengths, intensity
interferometry may increase the spatial resolution achieved in optical astronomy by an order …

With its unprecedented light-collecting area for night-sky observations, the Cherenkov
Telescope Array (CTA) holds great potential for also optical stellar astronomy, in particular …

Highest resolution imaging in astronomy is achieved by interferometry, connecting
telescopes over increasingly longer distances and at successively shorter wavelengths …

Context. A long-held vision has been to realize diffraction-limited optical aperture synthesis
over kilometer baselines. This will enable imaging of stellar surfaces and their environments …

Optical imaging with microarcsecond resolution will reveal details across and outside stellar
surfaces but requires kilometer-scale interferometers, challenging to realize either on the …

Astronomers usually need the highest angular resolution possible, but the blurring effect of
diffraction imposes a fundamental limit on the image quality from any single telescope …

A new high-resolution radio spectropolarimeter instrument operating in the frequency range
of 15–85 MHz has recently been commissioned at the Radio Astronomy Field Station of the …
