  1. Measuring Ionisation parameters (ITP-WHT) Florencia Jiménez Luján BAL QSO meeting 2009 Jun 24 – 26 Bologna (Italy)

  2. Introduction • Data • Results • Future plans • Summary

  3. Unification of AGN (Active Galactic Nuclei) (NLR) QSO (Quasi-Stellar Object, or quasar, QUASi-stellAR) in the center of each AGN: black hole surrounded by an accretion disk moving clouds: BLR (fast) & NLR (slow) classification: orientation scenario vs. evolutionary scenario (both???) know the properties & composition of the medium (BLR) Urry & Padovani, 1995

  4. Unification of AGN (Active Galactic Nuclei) No absorbers BAL QSO (Quasi-Stellar Object, or quasar, QUASi-stellAR) in the center of each AGN: black hole surrounded by an accretion disk moving clouds: BLR (fast) & NLR (slow) classification: orientation scenario vs. evolutionary scenario (both???) know the properties & composition of the medium NAL Elvis, 2000

  5. Unification of AGN (Active Galactic Nuclei) BALQSO have convex radio spectra (typical of CSS/GPS “young” radio sources) CSS: Compact Steep Spectrum; GPS: Gigahertz Peaked Spectrum QSO (Quasi-Stellar Object, or quasar, QUASi-stellAR) in the center of each AGN: black hole surrounded by an accretion disk moving clouds: BLR (fast) & NLR (slow) classification: orientation scenario vs. evolutionary scenario (both???) know the properties & composition of the medium Montenegro-Montes et al., 2008

  36. Data analysis of all BAL QSOs (ITP-WHT) • Comparison with other method (power-law model, Arav’s group). Check compatibility for pure partial covering model with this method (q11_020, q11_039 compatible) • Variability (q11_030) • Line-locking • Estimation of the distances from the absorbers to the central sources (electron densities, VLT data)

  37. Data reduction of all BAL QSOs (ITP-WHT) • Errors in covering factors and optical depths from errors in Ib and Ir (errors in column densities and ionisation parameters from those ones) • Resampling for different exposures • Analysis of q11_020 and q11_039 (Ionisation parameters determination) • Compatibility with other method (Arav’s group) for pure partial covering model
