MAVIS: sharper than JWST, deeper than HST

MAVIS (MCAO Assisted Visible Imager and Spectrograph) is a proposed instrument for the ESO’s VLT Adaptive Optics Facility, currently at the end of phase A with a large contribution from INAF. It is made of two main parts: a Multi-Conjugate Adaptive Optics (MCAO) system, that cancels the image blurring induced by atmospheric turbulence in the visible on a large field, and its post focal instrumentation, a wide field imager and a IFU spectrograph, both covering the visible part of the light spectrum. MAVIS has the potential to be an extremely novel and powerful facility: with an angular resolution of 15 mas (close to 50 times better than the seeing limited conditions) and a powerful and sensitive post-focal instrumentation, MAVIS will be instrumental to bring answers to a number of astrophysical science questions, from solar system bodies, stellar evolution, BH seeds, up to the physical composition of high-z galaxies and early galaxy assembly.
