Scientific paper

Far-infrared-photometric observations made in July 1978, covering the large region empty of galaxies discovered by Kirshner et al. (1981), are reported and analyzed in terms of the Sunyaev-Zeldovich effect and recent hypotheses as to the presence and temperature of gas in the region. The observational data, corrected for the dipole anisotropy, reveal that any signal from the region is embedded in the sky noise, and that the upper limit of the change in temperature toward the 'hole' for any source of from 6 to 45-deg angular dimension is 0.1 mK. It is inferred that the Comptonization parameter toward the void is less than 0.02 and that the normalized density of the extragalactic gas is less than or equal to 0.5 (assuming that, as suggested by the data, gas is absent from the void). A further implication of this finding is that the hot gas of the universe is not sufficiently dense to close gravitationally.
