Blue-MUSE is a proposition for an integral-field-spectrograph based on the concept of the VLT / MUSE instrument, to be installed on one of the telescopes of the VLT on Cerro Paranal. Using the now well-trained technology of image slicers, the optical design allows to fully cover up to 2 arcmin² FoV on sky and retrieve the full 3D (spatial and spectral) information in a single exposure. Blue-MUSE will complement the MUSE instrument by observing at bluer wavelengths, from the atmospheric cut-off to the middle of the R band. It will have a much higher spectral resolution, with R=4000 in average over the spectral range.

Science Cases
With its wide spatial coverage and spectral resolution, Blue-MUSE is well-suited for a large variety of science cases, from solar system bodies to galactic an extragalactic fields. In particular:
- Resolved spectroscopy of stellar nebulae
- Crowded field spectroscopy and dynamics of globular clusters
- Nearby dwarf and low surface-brightness galaxies, tidal streams, intracluster light
- Physics of gas outflows and interplay with star formation at z>0.3
- Properties of rest-frame UV nebular lines (HeII, CIII], CIV) at intermediate redshift (0.5<z<3)
- Multiply-imaged lensed galaxies in massive cluster cores
- Lyman-alpha emission at z>0.2 and the circumgalactic medium
