摘要：AbstractThis work presents the optical observations for three galaxy pairs. We have presented the isophotal contours and geometrical analysis (x-center shift (xc), y-center shift (yc), ellipticity (Ellip = 1 − b/a)and position angle(P.A.)) for each component of the pair. The projected linear separationsrpand the relative velocityΔvof each pair have been determined.This sample of galaxy pairs has been reported by Karachentsev Catalog without interaction signs. Our analysis shows that the galaxies had signs of interaction (tidal tail and tidal bridge or only tidal tail). The length and thickness of the tidal tails and tidal bridges have obtained and presented in this study.Our results show that two of the galaxy pairs are close pairs, i.e. contact systems (rp<30h70-1kpcandΔv<200km/s) with the tidal interaction of tails and bridges. While the other pair is an intermediate pair (30
