Environmental processes at work in galaxy clusters: triggering of the AGN activity and development of X-ray tails
We exploited the archival Chandra data to explore the connection between the X-ray emission and the ram-pressure stripping phenomenon in cluster galaxies extracted from the GASP survey. The X-ray analysis, coupled with the MIR-WISE colors, confirms the presence of AGNs at the center of galaxies with AGN-like optical line ratios. For the other candidate ram-pressure stripped galaxies with X-rays counterparts, the most likely interpretation is the presence of an obscured AGN with extended X-ray emission. Furthermore, for the galaxies that could benefit from long Chandra exposure times, a clearly X-rays emitting tail has been detected, suggesting a complex interplay between the galaxy ISM and the surrounding ICM. The hot plasma responsible for the extended emission is most likely responsible both for the X-ray emission and for the [OI]/H excess found from the analysis of the optical line ratios. Our analysis of the magnetic fields in the tail of JO206 suggests this could be a direct consequence of the ICM draping and demonstrates the extremely powerful capabilities of joint multiwavelength datasets.
