Descripción
Topics discussed in this issue include active galaxies and cosmology,
interstellar and intergalactic medium, and astronomical instrumentation.
Papers are presented on modeling rich clusters of galaxies, optical
variability of NGC 7469 in 1967-1987, the structure of the broad line
region in Fairall 9, the resolution of the compact core of quasars and
active galaxies with the gravitational lens effect, and galaxy formation
in pancake models. Consideration is also given to molecular clouds
around outflow sources, modeling OH in regions of star formation,
density studies of giant extragalactic H II regions, observations of the
star formation region NGC 7129, and interstellar medium parameters
derived from low-frequency variability. Other papers are on recent
developments of IR array cameras in France, an automated astrographic
plates measuring process, a low-resolution spectrophotometer for
measuring the integrated color of galaxies, the HUS solar flare and
cosmic gamma-ray burst detector aboard the Ulysses spacecraft, and the
Grecos operating system of the GCT.
