Dark Matter Mapped

Authors: George Rajna

A Yale-led team has produced one of the highest-resolution maps of dark matter ever created, offering a detailed case for the existence of cold dark matter-sluggish particles that comprise the bulk of matter in the universe. [25] The PICO bubble chambers use temperature and sound to tune into dark matter particles. [24] A detection device designed and built at Yale is narrowing the search for dark matter in the form of axions, a theorized subatomic particle that may make up as much as 80% of the matter in the universe. [23] The race is on to build the most sensitive U.S.-based experiment designed to directly detect dark matter particles. Department of Energy officials have formally approved a key construction milestone that will propel the project toward its April 2020 goal for completion. [22] Scientists at the Center for Axion and Precision Physics Research (CAPP), within the Institute for Basic Science (IBS) have optimized some of the characteristics of a magnet to hunt for one possible component of dark matter called axion. [21] The first sighting of clustered dwarf galaxies bolsters a leading theory about how big galaxies such as our Milky Way are formed, and how dark matter binds them, researchers said Monday. [20] Scientists from The University of Manchester working on a revolutionary telescope project have harnessed the power of distributed computing from the UK's GridPP collaboration to tackle one of the Universe's biggest mysteries – the nature of dark matter and dark energy. [18] In the search for the mysterious dark matter, physicists have used elaborate computer calculations to come up with an outline of the particles of this unknown form of matter. [17] Unlike x-rays that the naked eye can't see but equipment can measure, scientists have yet to detect dark matter after three decades of searching, even with the world's most sensitive instruments.
