Radio emission of Shakhbazian Compact Galaxy Groups
Three hundred fifty three radio sources from the NRAO VLA Sky Survey (NVSS) (Condon et al. 1998) and the FIRST Survey (White et al. 1997), are detected in the areas of 179 Shakhbazian Compact Groups (ShCGs) of galaxies. Ninety three of them are identified with galaxies in 74 ShCGs. Six radio sources have complex structure. The radio spectra of 22 sources are determined. Radio luminosities of ga...

متن کاملGalaxy Photometry in the Cluster Shakhbazian I
Newly obtained photoelectric V magnitudes for three galaxies in Shakhbazian I, when combined with the virial analysis of Robinson and Wampler, show that the cluster mass-to-luminosity ratio is WL ~ 4. The first brightest galaxy in the cluster (an elliptical) has (U—B) and (B—V) color indices which are consistent with those of normal ellipticals in the Virgo and Coma clusters, and it is suggeste...
متن کاملCompact groups in the UZC galaxy sample ?
Applying an automatic neighbour search algorithm to the 3D UZC galaxy catalogue (Falco et al. 1999) we have identified 291 compact groups (CGs) with redshifts between 1000 and 10 000 km s −1. The sample is analysed to investigate whether Triplets display kinematical and morphological characteristics similar to higher order CGs (Multiplets). It is found that Triplets constitute low velocity disp...
متن کاملThe Evolution of Galaxy Disks in Dense Environments – Lessons from Compact Galaxy Groups
Disk galaxies in compact galaxy groups exhibit a remarkable shortfall of neutral hydrogen compared to both isolated spirals and spirals in more loose groups, but the origin of this Hi deficiency remains unclear. Based on a sample of highly Hi deficient compact galaxy groups, here updated to also include HCG58 and 93, we summarise the first results of a multiwavelength campaign aimed at understa...
