[CII] line emission from spiral galaxies

2008
We have measured 158 μm [CII] line emission from a sample of thirteen gas rich galaxies. The new data are combined with the previous sample of six infrared bright galaxies of Crawford et al. 1985. The [CII] line is bright in all of the galaxies detected amounting to between .1 and 2% of the total nuclear far-infrared (FIR) luminosity, and is therefore ...

Emission-line variability in Seyfert galaxies

Publications of the Astronomical Society of the Pacific, 1988
Observations and theory of emission-line variability in Seyfert galaxies are reviewed in the context of standard photoionization models of the emission-line regions. Expected time scales for variability and systematic effects which can give misleading results are discussed. Published observations of emission-line variability are summarized.

Redshift surveys of emission-line galaxies

Publications of the Astronomical Society of the Pacific, 1988
The usefulness of employing samples of emission-line galaxies as alternative means of conducting redshift surveys is discussed. Results in the directions of the Bootes and Coma voids show certain differences. In Bootes approximately ten objects have been identified within the void, but the Coma void appears empty at the same luminosities. The Coma void

Broad emission lines in active galaxies

Vistas in Astronomy, 1988
Une etude theorique sur les raies d'emission larges dans les noyaux actifs de galaxies est presentee. Les problemes observationnels et theoriques sont etudies, un modele semi-consistant est propose. Il est montre comment les raies d'emission larges peuvent etre utilisees comme sondes de la dynamique des ecoulements gazeux dans les noyaux ...
