An article accepted for publication in the journal “The Monthly Notices of the Royal Astronomical Society” reports the results of the observations of Abell 2146, composed of two galaxy clusters in their merger phase. A team of researchers led by Helen Russell of the British University of Nottingham used NASA’s Chandra X-ray Observatory to study the shock wave that formed along the collision between the two clusters and is about 1.6 million light-years long. The processes in place show similarities with others that occur on a much smaller scale such as those generated by the solar wind.
