Investigation of the Gravitational Interaction between the Components of the Galaxy Pairs CPG 165

Abstract: In this paper the effect of interaction between the components of the galaxy pair CPG 165 on the symmetry of their morphologies and structures is studied by applying the technique of surface photometry. For each component of the pair we present the isophotal contours, profiles of surface brightness (SB), major-axis position angle (PA), and isophotal center-shift. The present analysis is done using the r- and i-band images from the Sloan Digital Sky Survey (SDSS) observation. It is found that the position angle and the isophotal center shift are strongly affected by the state of interaction between the components of the pair CPG 165.
