Alan McConnachie Colloquium: Introducing the next generation of the CFHT: the Maunakea Spectroscopic explorer

Marsfield Lecture Theatre

Abstract

The Maunakea Spectroscopic Explorer (MSE; previously, the ngCFHT) is a science-driven project that can fill a strategic “missing link” in the international suite of astronomical capabilities in the 2020s, namely dedicated, 10m-class, wide-field, extremely multiplexed spectroscopy. In addition to stand-alone science, such a capability can act as a feeder facility for the TMT, GMT, and E-ELT, a follow-up facility for wide field imaging surveys such as PS1, SkyMapper and LSST, and compliments key facilities at other wavelengths, such as SKA and eROSITA. After completion of a Feasibility Study involving over 60 scientists from 11 countries examining key scientific and technical aspects, a Project Office has been established. The PO follows a recommendation by the CFHT SAC and is charged with developing a Construction Proposal for the project to inform future considerations, and to act as a nucleus for the continued scientific, technical and partnership development of the project. Australia has a prominent role in key MSE science, such as Galactic archaeology and galaxy evolution, a strong heritage in wide field surveys, and has previously participated in the feasibility studies. Here, I will update the community on these developments, discuss the principal science drivers and requirements for the facility, and discuss opportunities for participation in the continued scientific and technical development of this exciting and broad-impact facility.
