Presentation Transcript

  1. Ly-beta emission line Ly-alpha emission line

  2. LyaF Future: 3D map of LSS • SDSS-III/BOSS quasar density (20 per sq. deg.) • WFMOS can do up to ~8 times denser • 100 Mpc/h deep • 400 times this volume in SDSS

  3. Current: very sparse • SDSS-II quasar density (1 per sq. deg.) • 100 Mpc/h deep • 400 times this volume in SDSS

  4. Primordial power spectrum parameters WMAP 5-year Eisenstein et al. BAO Includes tensors

  5. Matter density-power amplitude constraint WMAP 5-year Eisenstein et al. BAO Includes tensors

  6. Primordial power spectrum parameters WMAP 5-year Eisenstein et al. BAO

  7. Current parameter highlights (all including tensors, kp=0.05 1/Mpc, WMAP5+Eisenstein BAO+LyaF) (for T/S, BAO & LyaF independently find this level) • With WMAP3, sum m_nu < 0.2 eV

  8. Observed (3D) power Ideal 3D power (perfectly sampled) Resolution Sampling noise n=surface density of lines of sight (analogous to galaxy shot noise) Detector noise

  9. Simulated 3D flux power, relative to real-space linear theory(McDonald 2003) Bottom to top on left: mu= 0-0.25, 0.25-0.5, 0.5-0.75, 0.75-1.0

  10. Theory/fitting formula for redshift-space power • Linear theory on large scales • Non-linearity + pressure + fingers-of-god • Baryon wiggles simply modify P_L(k)

  11. Parameter dependence of 3D flux power (McDonald 2003) Black - increased amplitude Red - increased slope Solid - LOS Dotted - transverse

  12. Parameter dependence of 3D flux power (McDonald 2003) Black - increased temperature Red - increased dependence of temperature on density (gamma-1) Solid - LOS Dotted - transverse

  13. Parameter dependence of 3D flux power (McDonald 2003) Black - increased <F> Red - never mind (related to Jeans filtering) Solid - LOS Dotted - transverse

  14. Future BAO: Measure 3D power • Band power measurement from BOSS • Black: radial • Green:transverse • Red: diagonal • Dotted: Seo & Eisenstein non-linear smearing • Normalizations compressed.

  15. Constraints vs. resolution R= 62.5, 125, 250, 2000 (This was for a WFMOS-like survey, less area than BOSS)

  16. Expected BAO distance scale constraints from BOSS
