Three clusters of galaxies are about to collide in the universe

Astronomers capture impressive collision in progress at least three clusters of galaxies uniting the Chandra Observatory POTXMM-Newton WHICH and three radio telescopes.

clashes and merges of this type are the main way that clusters of galaxies they can grow into the gigantic space structures seen today. They also act as the largest particle accelerators in the universe. POT.

unique event

cluster of galaxies the giant that forms from this collision is abell 2256, located 780 million light years from Earth. This is a composite image abell 2256 combines X-rays from Chandra and XMM, highlighted in blue, with radio data collected by the Metrewave Giant Radio Telescope (GMRT), Low Frequency Array (LOFAR), and Karl G. Jansky Very Large Array (VLA), all highlighted in red, plus optical and infrared Pan data -STARR in white and pale yellow.

Astronomers studying this object are trying to find out what gave rise to this unusual-looking structure. Each telescope tells its own part of the story. clusters of galaxies are among the largest objects in the universe and contain hundreds or even thousands galaxies individual. In addition, they contain huge reservoirs of superheated gas at temperatures of several million degrees Fahrenheit. Only X-ray telescopes like Chandra and XMM can see this hot gas.

The radio emission from this system comes from an even more complex set of sources. Their first galaxies, in which the radio signal is generated by particles ejected in jets from supermassive black holes at their centers. These jets are ejected into space in straight, narrow lines (those labeled “C” and “I” in the annotated image according to the astronomical naming system) or slow down as the jets interact with the gas that collides, creating complex shapes and filaments (” A, B, and F). Source F contains three sources, all created by a black hole in galaxy aligned with the leftmost font of this trio.

The radio waves also come from huge filamentous structures (labeled “relics”), most of which are located north of galaxies radio stations, probably created when collision he created shock waves and accelerated particles in a gas over two million light-years away.

Finally, there is a “halo” of radio emission, located near the center collision. Because this halo overlaps with X-rays and is dimmer than the filamentary structure and galaxies, another radio image was created to highlight the weak radio emission. (Europe Press)
