TeVeS born (Bekenstein 2004)
• Einstein-like metric, extra scalar field
• In a quasi-static system with a weak gravitational field, lum+φ:
dτ2 = (1+2) dt2 - (1-2) ( dx2 + dy2 + dz2 )
• DM view lum+φDM
Updated Resume TeVeS
• 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
dτ2 = (1+2) dt2 - (1-2) ( dx2 + dy2 + dz2 )
Analogy: Polarisied DielectricM Q
• Field E = g = -▼Φ
• Φ = Charges + Polarised Dipoles• Displacement D = μ E = E + P
– TeVeS glum = g - ScalarField
• DM view ~ microscopic dipoles, extra field view ~ polarisation field
– 1-to-1

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 z=1000 without fine-tuning.
• Time to take TeVeS seriously.
