  1. A bifront infrared spectrometer highly optimized both for high & low spectral resolution Principal Investigator: Livia Origlia - INAF - Bologna Project Manager: Ernesto Oliva - INAF - Arcetri / CGG Bologna, January 2004

  2. WHY GIANO ? 2nd generation of TNG instruments according to the prescription of the Gruppo Istruttorio per il TNG • NICS 2 • UV-optimized spectrograph • high resolution IR spectrograph • call for proposal: deadline November 2002 • project presentation: March 2003 • GIANO approved to phase A: July 2003:50,000 euro assigned • GIANO Preliminary Design Review: December 2003

  3. GIANO: Instrumental Concept requirements:wide spectral coverage, ultra-stable, fast track, low-cost

  4. LR/VLR : 130 (1.5” ) 1,000 (0.5” ) slit length: 30”, 26/16 orders, 0.7 – 2.5 m HR : 16,000 (1.5” ) 50,000 (0.5” ) slit length: 6.5”, 56 orders, 0.9 – 2.5 m GIANO: observing modes slits: 0.5”, 0.75”, 1.0”, 1.5” polarimetric unit

  5. Osservatorio di Bologna • management & administration • scientific coordination • high - level software, WEB page • People: • L.Origlia, E.Rossetti, P.Montegriffo, • M.Lolli, A.Piccioni, R.Abicca, A.Caiulo • Centro Galileo Galilei • management & procurement • integration at the telescope • People: • E.Oliva, F.Ghinassi, M.Lodi • Osservatorio di Catania • pre-slit optics • polarimetry • People: • F.Leone, S.Scuderi, P.Bruno task distribution: • Osservatorio di Arcetri • optics, mechanics, cryogenics • electronics & low-level software • scientific coordination • People: • S.Gennari, V.Biliotti, C.Baffa, R.Maiolino, • C.DelVecchio, E.Giani, A.Checcucci, G.Falcini • INOA di Firenze • absorption cells • People:F.D’Amato

  6. GIANO: Management @29 man yrs man power … @ 23 people expected cost … @30% array 650 K$ + 650 Keuro @2 yrs for array delivery time scheduling … @ 3 years

  7. GIANO: Expected Performances high instrumental efficiencies HR : 17% , LR : 23% , VLR : 26% limiting magnitudes (conservative, based on real arrays) LR(R=500, 4hr, S/N=10) 20inJ , 19inH , 18 in K …UKIDSS HR(R=25,000, 4hr, S/N=10) 17.1inJ, 16.6inH & 15.4inK … 2MASS

  8. Gemini South ESO VLT Paranal Keck II Mauna Kea • NIRSPECin echelle mode • range: 0.9 – 5.5 mm • R=25,000with0.4”slit • slit lenght: 8”-12” • coverage: @2000Å • array: InSb 10242 • CRIRES …from 2005… • single order echelle • range: 1 – 5 mm • R=20,000 with 1” slit • slit lenght: 50” • coverage: @250Å • array mosaic: 3 InSb 10242 • Phoenix • single order echelle • range: 0.8 – 2.5 mm • R=75,000with0.17”slit • slit lenght: 60” • coverage: @200Å • array: InSb 10242 GIANO: comparison with other instruments high resolution narrow slits & coverage, single lines of bright stars Rmax @ 33,000 poorly stable narrow coverage, single lines GIANO highly competitive!

  9. TNG La Palma • NICS + AMICI: • range: 0.8 – 2.5 mm • R=50 with 1” slit • slit lenght: 4’ • array: HgCdTe 10242 GIANO: comparison with other instruments low resolution SEDs, no lines

  10. SF regions rocky planets cool stars SBs AGNs EROS DLAs low resolution … 10 AU 100 pc 500 Mpc high-z high resolution … QSOs minor bodies 1000 AU 100 pc 5 kpc 5 Mpc 50 Mpc high-z BDs GIANO: Scientific Drivers
