METIS: The Mid-Infrared E-ELT Imager and Spectrograph
Sarah KendrewLeiden Instrumentation Group
One of eight potential instruments for the European ELT, the largest planned optical/IR telescope for the next decade
A state-of-the-art mid-infrared instrument that will uncover unexplored parameter space at unprecedented resolutions (spatial + spectral)
A large international collaboration led from Leiden
An important part of the Netherlands’ strategy for next-generation optical/IR astronomy
What is METIS?
Next Generation of Ground-based Telescopes in Optical/IR
Giant Magellan Telescope, 24m
Thirty Meter Telescope, 30m
European Extremely Large Telescope, 42m
First light ~ 2018-2020
Eight instrument studies (2008-2010)
METIS:Only instrument
for l > 3 mm!
• METIS (NL PI)• MICADO• EPICS• OPTIMOS
Instrument selection and roadmap in 2010 by ESO
METIS is only NL-led E-ELT instrument
Leiden METIS team is:• Bernhard Brandl, Principal Investigator• Frank Molster, Project Manager• Remko Stuik• Laurent Jolissaint• Sarah Kendrew
Leiden science team members:• Ewine van Dishoeck• Paul van der Werf
Imaging at 3 14 µm (L, M, N bands)◦ Fov ~ 18x18”
Low-resolution slit spectroscopy Imaging polarimetry (N-band) Coronagraphy High-res integral field spectroscopy@ 3 5.5 (14?) µm
(R~100,000) Diffraction limited at all wavelengths◦ Adaptive optics to remove turbulence effects
METIS covers huge parameter space spatially & spectrally
METIS Concept
Exploring the cold & dusty Universe with METIS Conditions in the early Solar System, comets
Follow-up of GRBs
Ultra-luminous IR galaxies, starbursts, AGN
Galactic Centre studies
Star forming regions, protoplanetary disks,
planet formation
Detection & characterisation of exoplanets around
nearby stars
JWST
E-ELT
Martian atmosphere
ALMA
… and more ….
E-ELT + METIS will be an excellent complement to contemporary facilities
ALMA JWST
High spectral resolution in mid-IR
not available on JWST + E-ELT spatial resolution superior
E-ELT
Designing METIS: Science meets Engineering
