Transcript METIS: The Mid-Infrared E-ELT Imager and Spectrograph

Sarah Kendrew
Leiden 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


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
Conditions in the early
Solar System, comets
Follow-up of GRBs
Martian atmosphere
Ultra-luminous IR
galaxies, starbursts, AGN
Galactic Centre studies
JWST
Star forming regions,
protoplanetary disks,
planet formation
Detection &
characterisation of
exoplanets around
nearby stars
… and more ….
