Multi-Channel Spectroscopy (VKS)

The Multi-Channel Spectroscopy group is specialised in optical fibres and integrated optic waveguide devices. The group primarily targets applications on spectroscopy for astronomy to further expand the capabilities of multiplexed fiber-based spectroscopy in astronomy, as well as for interdisciplinary approaches and technology transfer.

The current portfolio of projects includes ELT-MOS/MOSAIC, Multiplex Raman Spectroscopy from Astrophysics to Medicine (MRS), Uro-MDD, HYPERAM, 4D-HTS, and support of the HETDEX project. MOSAIC is a multi-object spectrograph for the European Extremely Large Telescope, the flagship telescope project of European Astronomy for the next decades. The Multi-Channel Spectroscopy group is contributing a numerical simulation and experimental study of optical fibre properties, in particular concerning their stability, for use in the optical up to the H-band in the NIR. This work is part of a Phase-A study, awarded by ESO to the international MOSAIC consortium, led by GEPI Paris. The mid-term goal is submission of the Phase-A report to ESO by the end of 2017 and transition to Phase-B. VKS has previously also supported studies for VIRUS and 4MOST instruments.

The Multi-Channel Spectroscopy group is also involved in research on stars in the spiral galaxy NGC 300. By telling the story of how astronomy has reached this point, Prof. Dr. Martin M. Roth helps us understand why this result is so exciting. Visit the related blog here.
