Winds launched by a supermassive black hole impact the formation of new stars in the galaxy Markarian 34. The fraction of light coming from a young stellar population (YSP) increases at the edges of the approaching side of the wind (blue contours) compared to the rest of the galaxy. The receding side of the wind, faster and more turbulent (red contours), might be preventing star formation. Credits: HST/MAST Archive and G. Pérez Díaz.
