Abstract

Cygnus X-3 has been observed during 1988-1990 by the Whipple Observatory collaboration using the 109 pixel high-resolution γ-ray imaging telescope. The data recorded has been analyzed to search for (a) steady emission of TeV γ-rays, (b) 4.8 hr modulation of the γ-ray light curve, and (c) periodic emission at 12.59 ms. No evidence is found for emission based on these searches. The upper limit (3 a) for long-term steady emission is 3.5 × 10^-12 photons cm^-2 s^-1, a factor of 10 below fluxes reported a decade ago for this energy.
