"In hierarchical models of galaxy formation, stellar tidal streams are expected around most\r\ngalaxies. Although these features may provide useful diagnostics of the LCDM model, their\r\nobservational properties remain poorly constrained. Statistical analysis of the counts and\r\nproperties of such features is of interest for a direct comparison against results from numerical simulations. In this work, we aim to study systematically the frequency of occurrence and\r\nother observational properties of tidal features around nearby galaxies. The approach featured\r\nhere is based on a visual classification of diffuse features around a sample of nearby galaxies,\r\nusing a post-processing of optical survey imaging optimized for the detection of low-surfacebrightness stellar structure. At the limiting surface brightness of this sample, 14 − 17% of the\r\ngalaxies exhibit evidence of diffuse features likely to have arisen from minor merging events.\r\nFor simulated images, the frequency is 16 − 19%. Our technique recovers all previously known\r\nstreams in the selected sample and yields a number of new candidates. We conclude that this\r\nmethodology provides a reliable foundation for the statistical analysis of diffuse circumgalactic features in wide-area imaging surveys, and for the identification of targets for follow-up\r\nstudies."^^ .
