摘要：
We have analyzed the intra-group light component of 3 Hickson Compact Groups (HCG 79, HCG 88 and HCG 95) with detections in two of them: HCG 79, with 46 +/- 11% of the total B band luminosity and HCG 95 with 11 +/- 26%. HCG 88 had no component detected. This component is presumably due to tidally stripped stellar material trapped in the group potential and represents an efficient tool to determine the stage of dynamical evolution and to map its gravitational potential. To detect this low surface brightness structure we have applied the wavelet technique OV-WAV, which separates the different components of the image according to their spatial characteristic sizes.
