Galactic superwinds may help galaxies leak ionizing radiation, Haro 11 study finds

Our new study of the nearby starburst galaxy Haro 11 has shown that strong X-ray-emitting superwinds may be a key mechanism enabling galaxies to leak ionizing radiation, which is believed to have played a major role in the ...
