The evolution of satellite galaxies is shaped by their constant interactionwith the circum galactic medium surrounding central galaxies, which in turn maybe affected by gas and energy ejected from the central supermassive black hole.However, the nature of this coupling between black holes and galaxies is highlydebated and observational evidence remains scarce. Here we report an analysisof archival data on 124,163 satellite galaxies in the potential wells of 29,631dark matter halos with masses between 10$^{12}$ and $10^{14}$ solar masses. Wefind that quiescent satellites are relatively less frequent along the minoraxis of their central galaxies. This observation might appear counterintuitiveas black hole activity is expected to eject mass and energy preferentially inthe direction of the minor axis of the host galaxy. However, we show that theobserved signal results precisely from the ejective nature of black holefeedback in massive halos, as active galactic nuclei-powered outflows clear outthe circumgalactic medium, reducing the ram pressure and thus preserving starformation. This interpretation is supported by the IllustrisTNG suite ofcosmological numerical simulations, where a similar modulation is observed eventhough the sub-grid implementation of black hole feedback is effectivelyisotropic. Our results provide compelling observational evidence for the roleof black holes in regulating galaxy evolution over spatial scales differing byseveral orders of magnitude.
