1. Differences of LCDM vs. TeVeS HongSheng Zhao @St Andrews

3. In a fair world Gravity  Baryon content
Same Gravity for
105 Msun gas cloud
= 105 Msun black hole
= 105 suns globular
= 105 suns dwarf gal
… any density profile
Blunt tool

4. Variance in self-gravity despite N1 = N2 =105 !
Unbound at r=200pc
Why still Bound?

5. One has only Baryon, One bound by Dark Matter!

6. Does this hold in MOND gravity?
Polarisation halo due to scalar field
Applies to all satellites
Or real dark halo
around some satellites

7. Different Roche Lobes in MOND,Newton,TeVeS, DM,

8. MOND-like gravity (Zhao & Tian 2006)

9. Roche Lobe shape changes with laws of gravity

11. External-field effect (EFE) on the small satellite m at distance R

12. Similar Enviornment, Different Territorial Claims

13. Large variance

14. Dark Matter/Baryon Exchange Rate Fluctuates
D/B =?
Fornax (10-100)
Milky Way (10)
Globulars (0-1)
Any ratio is possible?

15. Updating Scores LCDM TeVeS
