Lyaf future 3d map of lss
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


Current very sparse
Current: very sparse

  • SDSS-II quasar density (1 per sq. deg.)

  • 100 Mpc/h deep

  • 400 times this volume in SDSS

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

Theory fitting formula for redshift space power
Theory/fitting formula for redshift-space power theory

  • Linear theory on large scales

  • Non-linearity + pressure + fingers-of-god

  • Baryon wiggles simply modify P_L(k)


Parameter dependence of 3d flux power mcdonald 2003
Parameter dependence of 3D flux power theory(McDonald 2003)

Black - increased amplitude

Red - increased slope

Solid - LOS

Dotted - transverse


Parameter dependence of 3d flux power mcdonald 20031
Parameter dependence of 3D flux power theory(McDonald 2003)

Black - increased temperature

Red - increased dependence of temperature on density (gamma-1)

Solid - LOS

Dotted - transverse


Parameter dependence of 3d flux power mcdonald 20032
Parameter dependence of 3D flux power theory(McDonald 2003)

Black - increased <F>

Red - never mind (related to Jeans filtering)

Solid - LOS

Dotted - transverse


Future bao measure 3d power
Future BAO: Measure 3D power theory

  • Band power measurement from BOSS

  • Black: radial

  • Green:transverse

  • Red: diagonal

  • Dotted: Seo & Eisenstein non-linear smearing

  • Normalizations compressed.
