10 David Barrado CAFE First light on June 2011 Operative

11 David Barrado CAFE Echelle Spectrograph: Design based on FOCES. Designed to be used in the 2.2m. Very stable (no movable parts) Resolution: ± 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!!!

16 David Barrado 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 16

17 David Barrado 17 HEXA: 6.5m telescope for spectroscopic mapping Base-line: Aperture 6.5m FOV 1.5 deg 500 multiplexing High-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

18 David Barrado Requirements Summary Aperture: 6.5m diameter Output F# number = 3.6. (for the prime focus solution F#2.5 was used) Plate scale for 2M and 3M: 8.84 arcsec/mm (focal length 23.4m, F#3.6). Plate scale for 1M: 12.2 arcsec/mm (focal length m, F#2.5) FOV: 1º to 2º Ø (diameter) Image quality: seeing limited Spectral range: narrow band filters 100 Å in the whole wavelength range : 380 Å Å Optimized for fibers: Telecentric system and flat focal plane
