LOFAR Telescope Sees Ridge of Radio-Emitting Plasma between Two Merging Galaxy Clusters

Jun 10, 2019 by News Staff

Astronomers using the Low-Frequency Array (LOFAR) telescope network have detected a vast ridge of radio emission connecting the merging galaxy clusters...

Using the Cosmic Web Imager (CWI) to study a system with two quasars 10 billion light-years away, the astronomers have unveiled a protogalaxy being fed cool gas by a filament of the cosmic web. The quasar UM 287 is the larger object at right; the newly-discovered protogalaxy is above and to the left of UM 287. This picture combines a visible light image of the system with CWI data; a filament of the cosmic web can be seen funneling cold gas onto the protogalaxy.
