The Sunyaev--Zel'dovich effect and Hubble's constant
MRAO, The Cavendish Laboratory, Madingley Road, Cambridge, England.
Combining measurements of the thermal Sunyaev--Zel'dovich effect with X-ray
data allows calculation of a direct, physical estimate of Hubble's
Constant () without the need for distance-ladder-type arguments. I discuss
the random and systematic errors inherent in this method of estimating ,
and present the preliminary results obtained for A2218 of and for A1413 of . These two clusters of galaxies are part
of an orientation unbiased, X-ray selected sample.
