Description a failure to detect co(1-0) absorption from the hypothesized molecular torus in cygnus a could be due to the high rotation temperature resulting from a strong compact radio source (barvainis and antonucci, aj 107,#4, 1291). in that case, absorption should be seen for high j transitions, e.g. j=19-18, lambda = 145.0 micron. the determination of the linewidth could constrain the size of torus.

Mission Description The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
