Title: You see a Dark Apple, I see Non-Newtonian Field


1
You see a Dark Apple, I see Non-Newtonian Field
HongSheng Zhao _at_St Andrews, SUPA
This is NOT an Apple (Magritte) ? Lets call the
whole thing Potato-Tomato (Armstrong)

Resume _at_2004 LCDM
MOND
  • Solar System ?
  • Tides on Globulars dSph
  • Rot. curves HSB/LSB
  • Lensing by Ellipticals
  • HubbleExp./SNIa
  • Large-scale structure

3
  • TeVeS born (Bekenstein 2004)
  • Einstein-like metric, extra scalar field
  • In a quasi-static system with a weak
    gravitational field, ? ? ?lumf
  • dt2 (12?) dt2 - (1-2?) ( dx2 dy2 dz2 )
  • DM view ? ? ?lumfDM

Updated Resume TeVeS
dt2 (12?) dt2 - (1-2?) ( dx2 dy2 dz2 )
  • Solar System
  • Tides on Globulars dSph
  • (zhao 06)
  • Rot. curves HSB/LSB
  • (zhao, famaey 06)
  • Lensing by Ellipticals (zhao,bacon,taylor,
    horne)
  • HubbleExp./SNIa (zhao, skordis,
    mota 06)
  • Large-scale structure

  • DM view microscopic dipoles,
  • extra field view polarisation field

? u say DM, I say Scalar,? u say gDM , I say
?fteves u say NFW, I say µ(?f) , lets call the
whole thing
Pioneer Anomaly a-1 10-10m/s2

Predict Cosmology without further tuning
9
Connecting Cosmology with Galaxies
(Zhao,Famaey,ApJL)
Solar System
Early Universe
SNeIa
Edge of galaxies

  • Hubble expansion in TeVeS

You say ?, I say f, You say ODM, I say Gf

As good as ?CDM, but no ?!

Updated Resume LCDM TeVeS
  • Pioneer Anamoly ?
  • Tides on Globulars dSph
  • (zhao 06)
  • Rot. curves HSB/LSB
  • (zhao, famaey 06)
  • Lensing by Ellipticals (zhao,bacon,taylor,
    horne)
  • HubbleExp./SNIa (zhao, skordis,
    mota 06)
  • 3rd peak in CMB

Stay-tuned

Conclusion
  • A co-variant theory exists
  • whose Lagrangian fixed by fitting galaxies Vcir
    and solar system (a0 ,ap )
  • Predicts correct
  • late acceleration and
  • horizon at z1000 without fine-tuning.
  • Time to take TeVeS seriously.
