Description
Galaxy formation by gravitational instability implies the presence of
temperature fluctuations in the cosmic microwave background. New
observations at 10.45 and 14.9 GHz from the Observatorio del Teide in
Tenerife on angular scales of several degrees reveal structure of
galactic origin at the lower frequency, while at the upper frequency the
magnitude of fluctuations of cosmological origin must be less than 1.8 x
10 exp -5 on a scale of 5 deg. This strongly constrains models of galaxy
formation, and is compatible with the recently announced discovery by
the COBE satellite of fluctuations on larger angular scales.
