The Universität Hamburg receives around 500,000 euros from the German Research Foundation (DFG) for a spectrograph and supports its acquisition with a further 500,000 euros. The device is intended for an astronomical instrument in Chile that will be used in the future to conduct so-called galaxy surveys, which can record millions of galaxies and limit the possible properties of dark matter. In former times, astronomers were able to concentrate exclusively on one particular celestial object for years. Today, sky surveys - a kind of inventory of the universe - can also be used to record and study millions of astronomical objects. This will be made possible by equipment such as the multi-object spectrograph "4MOST", which will be installed at the Paranal Observatory of the European Southern Observatory (ESO) in northern Chile on the more than four-meter VISTA telescope. In contrast to previous models, 4MOST can simultaneously capture the spectra of thousands of celestial objects because their light is transmitted to three spectrographs via special optical fibers. One of them is funded by the DFG with 500,000 euros and another 500,000 euros by the Universität Hamburg.
