NED Abstract

Copyright by Royal Astronomical Society. 1991MNRAS.248..112W Optical identifications of IRAS point sources: the Fornax, Hydra I and Coma clusters G. Wang, R. G. Clowes, S. K. Leggett, H. T. MacGillivray and A. Savage Astronomy Department, Edinburgh University, Blackford Hill, Edinburgh EH9 3HJ Royal Observatory, Blackford Hill, Edinburgh EH9 3HJ UK Schmidt Telescope, Anglo-Australian Observatory, Coonabarabran, NSW 2357, Australia Accepted 1990 August 13. Received 1990 August 8; in original form 1990 July 12 SUMMARY We present optical identifications for 66 IRAS point sources in the region of the Fornax cluster of galaxies, 106 IRAS point sources in the region of the Hydra I cluster of galaxies (Abell 1060) and 59 IRAS point sources in the region of the Coma cluster of galaxies (Abell 1656). Eight other sources in Hydra I do not have optical counterparts and are very probably due to infrared cirrus. Twenty-three (35 per cent) of the Fornax sources are associated with stars and 43 (65 per cent) with galaxies; 48 (42 per cent) of the Hydra I sources are associated with stars and 58 (51 per cent) with galaxies; 18 (31 per cent) of the Coma sources are associated with stars and 41 (69 per cent) with galaxies. The stellar and infrared cirrus surface density is consistent with the galactic latitude of each field. Using available redshift data we have established 30 per cent of the IRAS galaxies in the Fornax region as cluster members, 51 per cent of those in the Hydra I region, and 63 per cent of those in the Coma region; there will be some cluster members that remain unrecognized. The relative frequency of the different morphological types is similar for the optical and infrared cluster samples - mainly ellipticals and lenticulars are detected by IFS in the Fornax and Coma clusters, and spirals in Hydra I. The most distant sample, the Coma cluster, contains the most infrared- luminous galaxies, although none of the cluster galaxies are extremely infrared-luminous - all have L_IR_ < 2 x 10^11^ L_sun_ for H_0_ = 50 km s^-1^ Mpc^-1^.
