1 INAF – Osservatorio Astronomico di Bologna Technology Introduction

2 late 70, early 80: starting... active users of ESO + HST since their onset 1 st key aspect: school of observational astronomy & data analysis Loiano telescopes entusiastic astronomers & fans of PSF + 1965 1985 + Technology: Visiting Committee – Bologna, Dec 3-5, 2007

3 2 nd key aspect: growing exigency of actively contributing in developping & optimizing observational strategies & analysis procedures for maximizing the scientific output modern instrument = hardware + software + science 3 rd key aspect: computer center : astronomers fond of software & software engineers fond of astronomy Technology: Visiting Committee – Bologna, Dec 3-5, 2007

4 TNG-GIANO GAIA 99 00 01 02 03 04 05 06 07 projects ESO-FLAMES: templates, GTO ESO-VIRMOS: DRS, RTD, GTO 2 nd floor astronomers + Bregoli,Lolli,Merighi,Montegriffo 1 st floor astronomers + Rossetti,Merighi ESO-MAD: WFS LBT: LBC+LINC-NIRVANA+IRTC ELT-MCAO Diolaiti,Lombini, Schreiber(Student) Diolaitis talk Origlias talk Pancinos talk Technology: Visiting Committee – Bologna, Dec 3-5, 2007

5 other actvities: TNG & ESO site testing/monitoring ( Zitelli, Lombardi (PhD) ) Treatment of astronomical mirrors: experiment for LBT ( Zitelli, Ciattaglia, Mezzini ) L3CCD: photon counting camera for WFS ( Bregoli,Ciattaglia, Innocenti, in collaboration with Cosentino & Foppiani – UniBo ) TNG: NICS software upgrading ( Rossetti, Guido (PhD) ) Technology: Visiting Committee – Bologna, Dec 3-5, 2007

6 astronomical software development: software for computing numerical PSF STARFINDER ( Diolaiti ) software for cross-correlation & astrometry of catalogs CATAPACK: CataXcorr+CataComb ( Montegriffo ) software for variable star analysis: GRATIS+VARFIND+VARCAT+ATMOS ( Montegriffo ) software for spectral & chemical abundance analysis DAOSPEC + ABOMAN ( Pancino, Rossetti ) Technology: Visiting Committee – Bologna, Dec 3-5, 2007

7 a high and low resolution near infrared (0.9-2.5 m) spectrometer for the Telescopio Nazionale Galileo (TNG) http://www.bo.astro.it/giano PI: L. Origlia (INAF-Bologna) PM: E. Oliva (INAF-FGG) dedicated to Sandro Gennari Technology - GIANO: Visiting Committee – Bologna, Dec 3-5, 2007

8 NICS 2 NICS 2 UV-optimized spectrograph UV-optimized spectrograph high resolution IR spectrograph high resolution IR spectrograph call for proposal: deadline November 2002 call for proposal: deadline November 2002 project discussion: March 2003 project discussion: March 2003 GIANO approved for phase A: July 2003 GIANO approved for phase A: July 2003 Preliminary Design Review: November 2003 Preliminary Design Review: November 2003 Final Design Review: December 2004 Final Design Review: December 2004 2 nd generation of TNG instruments 2 nd generation of TNG instruments according to the prescription of the Gruppo Istruttorio per il TNG Technology - GIANO: Visiting Committee – Bologna, Dec 3-5, 2007

9 main optics in double pass as collimator & camera TMA as collimator & camera minimize off-axis angles, thus optimizing the grating efficiency allow for large collimated beams (i.e. high res) in reduced space prisms as cross dispersers maximize efficiency & spectral coverage basic requirements / constraints: basic requirements / constraints: high resolution, wide spectral coverage, high trhoughput, high stability Technology - GIANO: Visiting Committee – Bologna, Dec 3-5, 2007

10 the 1st face of GIANO: HR mode uses the echelle grating for dispersing & prisms for cross-dispersing Technology - GIANO: Visiting Committee – Bologna, Dec 3-5, 2007

11 the 2nd face of GIANO: LR mode inserts a flat mirror and uses only the prisms for dispersing Technology - GIANO: Visiting Committee – Bologna, Dec 3-5, 2007

12 Hawaii2 - 2k x 2k echelleinfrasil ZnSe
