Beyond the Local Group. I. Cosmic Filaments Govern the Spatial Alignments of Galaxy Pairs

open access: yesThe Astrophysical Journal
Using a large observational sample from the Sloan Digital Sky Survey, we investigate the spatial alignment between galaxy pairs and their local cosmic filaments. Focusing on pairs with stellar masses and separations comparable to the Milky Way–Andromeda (
