Cosmic flows: review of recent developments

I review the recent developments in the analysis of cosmic flow data, in particular, latest results of bulk flow measurements, comparison between redshift and peculiar velocity catalogs with emphasis on the measured value of the β (= Ω0.6 m /b) parameter, and matter power spectrum estimates from galaxy peculiar velocity catalogs. Based on these developments, one can argue that most of the previous discrepancies in the interpretation of cosmic flow data, maybe with the exception of bulk flow measurements on scales >∼ 100h −1Mpc, have either been resolved or fairly understood.
