Wavefront correction with a ferrofluid deformable mirror: experimental results and recent developments
Denis Brousseau, Ermanno F. Borra, Simon Thibaul +7
We present the research status of a deformable mirror made of a magnetic liquid whose surface is actuated by a triangular array of small current carrying coils. We demonstrate that…

A cryogenic liquid-mirror telescope on the moon to study the early universe
Roger Angel, Simon P. Worden, Ermanno F. Borra +9
We have studied the feasibility and scientific potential of zenith observing liquid mirror telescopes having 20 to 100 m diameters located on the moon. They would carry out deep in…
