Abstract
This 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 separations rp and the relative velocity Δv of 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<30h70-1kpc and Δv<200km/s) with the tidal interaction of tails and bridges. While the other pair is an intermediate pair (30<rp<55h70-1kpc andΔv<5km/s) with the tidal tail in the western side.
