The internal and external pressure of interstellar medium clouds were measured by modelling of Atacama Large Millimeter Array and Very Large Telescope data. Pressure gradients indicated that both cloud collapse and expansion are possible in jet-driven outflows from black holes, potentially altering the star formation rate of their galaxies.

黑洞喷流触发可形成恒星的云的压缩和膨胀

星际介质云的内部和外部压力是通过阿塔卡马大毫米阵列和超大望远镜数据建模来测量的。压力梯度表明，在喷流驱动的黑洞外流中，云的塌缩和膨胀都是可能的，这可能会改变它们星系的恒星形成率。
