A Link Between Ram Pressure Stripping and Active Galactic Nuclei

Understand

The dense environment of a galaxy cluster can radically transform the content of in-falling galaxies.

• Recent observations have found a significant population of active galactic nuclei (AGN) within "jellyfish galaxies," galaxies with trailing tails of gas and stars that indicate significant ram pressure stripping.
• The relationship between AGN and ram pressure stripping is not well understood.
• In this letter, we investigate the connection between AGN activity and ram pressure in a fully cosmological setting for the first time using the RomulusC simulation, one of the highest resolution simulations of a galaxy cluster to date.
