1 Automated analysis: SDSS, BOSS, GIRAFFE Tests with MILES spectra (R~2000) from the INT (Sanchez Blazquez et al. 2006) The same code (FERRE) Fitting data calibrated in flux and continuumnormalized
2 Software Gaussian LSF (fiber, wavelength) Quadratic interpolation of fluxes Normalization by blocks Successful tests performed on MILES library

6 Recent trends in spectroscopic studies 3D model atmospheres: a beginning full NLTE: good progress for hot stars, but Data archival: survey projects going on with massive archives that become public (low-res: SDSS, SEGUE, GALEX) (high-res: Elodie, S4N) Analysis automation: a beginning Breaking the Z barrier
7 The Desirable future 3D model atmospheres full NLTE A pending observational test for solar-type stars: center-to-limb variation of the solar spectrum Data archival: VOs (including both observations and models) Stronger efforts to measure/compute atomic data Stronger efforts to use the newly available atomic data Full analysis automation R an ignored variable?

26 Big data and the cloud Trends are changing in observational astronomy Hand by hand, instrument development and computing are creating a new generation of machines geared to speed up discovery The biggest telescopes are, at least partially, not following that trend
27 Big data and the cloud Supercomputing is widely embraced for modeling and interpreting the data (plain good-old physics) Virtual observatories are developing quickly to ensure the legacy value of the data High-throughput computing widely adopted for large-scale projects, but only modest use of cloud services (e.g. HETDEX)
28 Data mashup Typical use of data is concentrating on a specialized data set This must change now with projects such as Gaia Analysis requires combining appropriately different types of data Bayesian statistics offers the framework to a combined analysis of astrometry, photometry and spectroscopy Tuesday, August 27, 2013

33 Structure of the halo Johnston & Bullock simulations Monolithic collapse and intensive accretion A dual halo split in rotation and [Fe/H]? Only place in the Galaxy where full orbits and chemistsry are preserved: ideal for stellar archaelogy
34 Chemical evolution Big bang nucleosynthesis Stellar nucleosynthesis: hydrostatic equilibrium, AGB Explosive nucleosynthesis ISM spallation Also destruction
35 Early Chemical Evolution Fast enrichment Extremely few stars expected (and found) at [Fe/H] < -4 Large scatter in abundances at [Fe/H]<4
36 Big Bang Nucleosynthesis Figure from Edward L. Wright Chemical abundances of the oldest stars constrain our model of the universe. Large discrepancy between CMB and stellar Li abundances
37 R-process is universal Sneden et al Oldest stars provide pure information on single SN events Nucleosynthesis patterns then and now seem to match in cases The fraction of carbon-rich stars increases at low
38 Mg/Fe Ca/Fe Only two stars Abundance currently known at ratios [Fe/H]<-5!! Y/Ba Ti/Fe Frebel 2010 Chiappini et al. 2011

41 BOSS spectra More resolution More spectral coverage More sensitivity Deeeper into the halo Privileged access to IAC >100,000 spectra in
42 BOSS analysis SEGUE obtained >300,000 stellar spectra Between SEGUE s pipeline can be used to compare with results from BOSS New analysis for BOSS spectra represents a significant improvement
43 Discovery process 1. Skim through BOSS database to pick the best candidates to have [Fe/H]<-4 2. Follow those up with higher quality: 4.2m WHT/ISIS, 10m GTC/OSIRIS 3. Investigate those that pass all the filters: 8m ESO/VLT, 10m GTC/OSIRIS, 10m HET/HRS (maybe HORUS)

50 Summary II Data indigestion? Stress should be placed on automated analysis And on a rigurous analysis of combined data (Bayesian framework) Parametric models, increasingly sophisticated, to become a workhorse. Are they Ready? Data can be directly used to determine distribution functions across the Galaxy to be Tuesday, August 27, 2013directly compared with numerical simulations
51 Conclusions We are living a golden era for the study of the Milky Way Gaia flies at the end of the year, first catalog probably out around 2016 and final catalog around 2020 Now is the time to get ready to use Gaia s data, and in particular to squeeze the information content in the combination of Gaia plus the other spectroscopic surveys Now is the time to sharpen our tools for Tuesday, August 27, automatic analysis and model-based 2013
