The satellite project is led by the Astro Space Center in Moscow, and the data from all 15 telescopes were combined at a facility of the Max Planck Institute for Radio Astronomy in Bonn, Germany. The scientists are reporting on their work in the Astrophysical Journal.
Galaxy clusters are often described by superlatives. After all, they are huge conglomerations of galaxies, hot gas, and dark matter, representing the largest structures in the universe held together by gravity. New observations of the galaxy cluster SPT-CLJ2344-4243 (or Phoenix Cluster) at X-ray, ultraviolet, and optical wavelengths are helping astronomers better understand this extraordinary system.
About 250 million light-years away, there’s a neighbourhood of our universe that astronomers had considered quiet and unremarkable. But now, scientists have uncovered an enormous, bizarre galaxy possibly formed from the parts of other galaxies. Some 718,000 light-years across, UGC 1382 is more than seven times wider than the Milky Way.
New results from NANOGrav — the North American Nanohertz Observatory for Gravitational Waves — establish astrophysically significant limits in the search for low-frequency gravitational waves. This result provides insight into how often galaxies merge and how those merging galaxies evolve over time.
