摘要：
Galaxy formation is thought to involve the cooling of gas in dark-matter haloes collapsing under the influence of gravity and the expansion of the Universe. Cosmologists have a problem with this model though: it produces too many bright galaxies. Unless, that is, young galaxies eject large amounts of gas in the form of high-speed outflows. A new technique, integral field spectroscopy has now been used to gather the best evidence yet that such processes actually occur.
