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
