| Sunyaev-Zeldovich Effect |

|
| • | Note
that the S-Z effect + X-ray |
||||||||
| observations
over-constrain the |
|||||||||
| physical
conditions. With some |
|||||||||
| assumptions
then, the physical sizes of |
|||||||||
| the
clouds can be determined. |
|||||||||
| Comparison
of angular sizes then can |
|||||||||
| give
distances measured independent of |
|||||||||
| redshift,
and thus used to make |
|||||||||
| estimates
of Hubble’s constant. |
