Rings of star formation: Imprints of a close galaxy encounter
arXiv:1412.4443 · doi:10.1017/S1743921314009508
Abstract
In this talk, I report results from galaxy merger simulations, which suggest the existence of a ring of star formation produced by close galaxy encounters. This is a generic feature of all galaxy interactions, provided that the disc spins are sufficiently aligned. This signature can be used to identify close galaxy pairs that have actually suffered a close interaction.
