CAFE

Echelle Spectrograph: Design based on FOCES. Designed to be used in the 2.2m. Very stable (no movable parts) Resolution: 62000 ± 5000 (from blue to red). Wavelength Range: 3960 – 9500 A. Sensitivity: SNR~30 for a point-like source of V~14.5

magnitudes in a single integration of 2700s. 2 times more sensitive than FOCES at its best

resolution!!!

Why HEXA? Two decades of large photometric surveys: SDSS, 2MASS, WISE), there is a need

of massive spectroscopy. This is the CAHA niche. The combination of both (photometric and spectroscopic) sets of data will allow the solution of open key problems like the assembly and evolution of galaxies, the

BAOs, and stellar archeoastronomy, among others. Extragalactic science: a) Of better spectral resolution (e.g. search for supermassive blackholes), b) with a larger spatial coverage (e.g. IFUs to resolve properties of nearby objects, as it

is the case of CALIFA - an ongoing legacy project in CAHA - or MaNGA),c) deep enough to observe low surface brightness galaxies (to ensure completeness of

galaxy samples at low luminosities). Stellar case will be dominated by the results of the GAIA mission (one billion stars

down to magnitude V 20, but radial velocities and chemical abundances only for restricted subsamples). Under these conditions, a massive acquisition of spectroscopic data is essential to take profit of the enormous GAIA potential. Gaia-ESO

"Astronet infrastructure road map" and "Science Vision for European Astronomy" reports (e.g. SV B7 at http://www.astronet-eu.org/).

HEXA: 6.5m telescope for spectroscopic mapping

Base-line:Aperture 6.5mFOV 1.5 deg500 multiplexingHigh-spectral resolution (R>20,000, optimal 50,000)

Science with HEXA: some examples

a) Gaia follow-up: properties and evolution of stars and stellar associations

b) Plato: characterization of exoplanets

c) Extragalactic: post-CALIFA

d) Cosmology: post-ALHAMBRA

e) Cosmology: dark energy and acustic barionic oscilations

CAFE

International Consortium leaded by CAHA (PI: S.F. Sánchez), with the collaboration of:

Observatory of Munich University (Dr. F. Grupp). Gottingen Unisersity (Dr. S. Drezzler).

Total Budget: 350k Euros: 80% of the Budget paid with money from the

MICINN (ICTS-2008-32 and ICTS-2009-24), and the Junta da Andalucía (PWM-08-306 through IAA).

20% of the Budget paid by Gottingen University. Design provided by the Obs. Munich University.

CAFE: Development.

Developed between 2008 and 2011. First Light: May 2011. Commisioned along the

summer of 2011. Improvements with respect to FOCES:

Termalized and vibration proved location. Minimum Motorized and Mobile systems: (1) Fixed

setup but (2) much more stable! New fiber system: increase of efficiency. New CCD: increase of efficiency. New electronic system: Reliability. Fully automatized Pipeline (Beta version).
