TL;DR
This paper investigates the prevalence of massive starbursts in interacting galaxies by analyzing a large sample of simulations and comparing them with recent observational data to understand the diversity of galaxy responses to tidal interactions.
Contribution
It provides a comprehensive analysis of ~1000 galaxy interaction simulations and compares the results with observational studies to assess starburst occurrence.
Findings
Massive starbursts are common in interacting galaxies.
Simulation results align with recent observational findings.
Galaxy response to interactions varies widely.
Abstract
Many evidences exist for a connection between galaxy interactions and induced star formation. However, a large range of responses of galaxies to tidal interactions is found, both in observations and in numerical simulations. We will discuss some recent results obtained analysing a large sample (~ 1000) of simulations of interacting pairs and their agreement with the most recent observational works.
