  1. CAHA: scienceplanning, internationalagreements and strategicplanningforthenextdecade Madrid, 22-23, 2012 David Barrado

  2. The sky at Calar Alto • 3.5m, 2.2m (& 1.23m, Schmidt) • OAN 1.5m • INTA 0.5m • GAW (cherenkov telescopes) 0.170 mag/airmass 0.80 arcsec

  3. The sky at Calar Alto Hours observed • Useful: • 2010: 2023 hr • 2011: 2300 hr Clear nights Clear: at least 6 observing hours of clear or mostly clear sky • Photometric: • 2010: 58 n • 2011: 106 n • Clear: • 2010: 150 n • 2011: 193 n Fraction of useful time: ~70% (~40% of the nights are 100% useful) Analysis published in refereed journals (Sanchez et al. 2007, 2008)

  4. Light Pollution • July 2007.- The regional government of Andalusia (Junta de Andalucía) approved an environmental lawthat includes a chapter on light pollution. • August 2010.- Ancillary regulation - The law foresees creating an Office for the Protection of Night Sky against Light Pollution, and Calar Alto has secured its participation in this official institution. - CAHAas a reference and as a place to be protected. • September 2010.- CAHA is named as member of the network for Clima Change (monitoring) • September 2011.- Meeting with towns to implement regulations • October 2011.- Meeting with Diputación de Almería (province) • Feb 14.- Map of pollution by Junta de Andalucía

  11. 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!!!

  12. CAFE: some spectra

  14. Nueva instrumentación: Carmenes (2014) • Objetivo: búsqueda y caracterización de exotierras alrededor de • estrellas frías • Técnica: Velocidad radial • Hardware: Espectrógrafo en los rangos ópticos (Heidelberg) e IR (IAA, Granada)

  16. 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/).

  17. HEXA: 6.5m telescope for spectroscopic mapping • Base-line: • Aperture 6.5m • FOV 1.5 deg • 500 multiplexing • High-spectralresolution (R>20,000, optimal 50,000) • Sciencewith HEXA: someexamples • a) Gaiafollow-up: properties and evolution of stars and stellarassociations • b) Plato: characterization of exoplanets • c) Extragalactic: post-CALIFA • d) Cosmology: post-ALHAMBRA • e) Cosmology: darkenergy and acusticbarionicoscilations

  18. 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 16.25 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 -11000 Å Optimized for fibers: Telecentric system and flat focal plane
