Multi-unit Spectroscopic Explorer
The multi-unit spectroscopic explorer (MUSE) is an integral field spectrograph installed at the Very Large Telescope (VLT) of the European Southern Observatory (ESO). It operates in the visible wavelength range, and combines a wide field of view with a fine spatial sampling and a large simultaneous spectral range. It is designed to take advantage of the improved spatial resolution provided by adaptive optics. MUSE had first light on the VLT on 31 January 2014. 6. These sources can be extremely faint, in which case they can only be detected using through the emission in the Lyman-alpha emission line, such galaxies are frequently referred to as Lyman-alpha emitters. A common way to study such sources is to use narrow-band imaging, but this technique can only survey a very narrow redshift range at a time – set by the width of the filter. In addition this method is not as sensitive as direct spectroscopic studies because the width of the filter is wider than the typical width of ...

MUSE On Nasmyth Side View
In ancient Greek religion and mythology, the Muses ( grc, Μοῦσαι, Moûsai, el, Μούσες, Múses) are the inspirational goddesses of literature, science, and the arts. They were considered the source of the knowledge embodied in the poetry, lyric songs, and myths that were related orally for centuries in ancient Greek culture. Melete, Aoede, and Mneme are the original Boeotian Muses, and Calliope, Clio, Erato, Euterpe, Melpomene, Polyhymnia, Terpsichore, Thalia, and Urania are the nine Olympian Muses. In modern figurative usage, a Muse may be a source of artistic inspiration. Etymology The word ''Muses'' ( grc, Μοῦσαι, Moûsai) perhaps came from the o-grade of the Proto-Indo-European root (the basic meaning of which is 'put in mind' in verb formations with transitive function and 'have in mind' in those with intransitive function), or from root ('to tower, mountain') since all the most important cult-centres of the Muses were on mountains or hills.
