Optical identifications of IRAS point sources - The Fornax, Hydra I and Coma clusters
Optical identifications are presented for 66 IRAS point sources in theregion of the Fornax cluster of galaxies, 106 IRAS point sources in theregion of the Hydra I cluster of galaxies (Abell 1060), and 59 IRASpoint sources in the region of the Coma cluster of galaxies (Abell1656). Eight other sources in Hydra I do not have optical counterpartsand are very probably due to IR cirrus. Twenty-three (35 percent) of theFornax sources are associated with stars and 43 (65 percent) withgalaxies; 48 (42 percent) of the Hydra I sources are associated withstars and 58 (51 percent) with galaxies; 18 (31 percent) of the Comasources are associated with stars and 41 (69 percent) with galaxies. Thestellar and infrared cirrus surface density is consistent with thegalactic latitude of each field.
| Correlations between NH3(1,1) and far-IR emission
NH3 (1,1 and 2,2) observations obtained using a 1024-channelautocorrelator and K-band maser amplifier at the 100-m Effelsberg radiotelescope (angular resolution 40 arcsec at 1.3 cm; velocity resolution0.16 km/s; rms error 0.1 K) are reported for six Taurus-region IRASsources for which the 100-micron flux is greater than the 60-micronflux. The data are presented in maps and tables and compared with theIRAS FIR data in graphs. A strong correlation between the NH3 lineintensity and the 100-micron flux and an anticorrelation between peakmain-beam brightness temperature and Delta-V (where V is the linevelocity) are observed and found to be consistent with the hypothesis ofHenriksen and Turner (1984), that the velocity field in molecular cloudsis controlled by star/cloud turbulence, with a conversion of small-scaleangular momentum to larger-scale turbulence.
