Finding the Origins of a Galactic Collision: Shock Dynamics in Stephan’s Quintet

The study examines the large-scale shock front in Stephan's Quintet, formed by galaxy collisions, using data from WEAVE, JWST, and radio telescopes. It reveals the shock's role in heating the intergalactic medium, boosting radio emissions, and allowing molecular hydrogen formation despite dust destruction. The findings highlight the complex interactions between shocks, gas, and dust, offering insights into how galactic collisions impact star formation and interstellar matter.
