What collisional debris can tell us about galaxies
Pierre-Alain Duc
TL;DR
This paper reviews how collisional debris, especially tidal tails, can provide insights into galaxy structure, formation history, merger processes, and fundamental gravity laws across the universe.
Contribution
It synthesizes current knowledge on how different types of collisional debris inform us about galaxy evolution and gravity theories.
Findings
Tidal tails reveal galaxy interaction history.
Collisional debris helps distinguish merger types.
Debris observations constrain gravity models.
Abstract
I review what tidal tails in particular, collisional debris in general, might tell us about galaxies (their structure, current content and past mass assembly) about mergers in the nearby and distant Universe (major vs minor, wet vs dry, number evolution) and finally about the laws of gravity.
