Scientists at Universität Hamburg and DESY have developed a globally unique mobile computer tomograph as part of the Excellence Cluster “Understanding Written Artefacts” (UWA). The researchers call their device ENCI (“Extracting Non-destructively Cuneiform Inscriptions”), a reference to Enki, the Sumerian god of wisdom. With the help of this device, scientists could read for the first time 4000-year-old cuneiform tablets that are sealed from view....

The scientific collaboration running the High Energy Stereoscopic System (H.E.S.S.) telescope, using observations with the Cherenkov Telescope Array located in Namibia, has detected very high-energy gamma-rays above several tera-electronvolts coming from the SS 433 microquasar’s "western" and "eastern" jets in our Galaxy. This confirms the first ever detection of a microquasar in the tera-electronvolt range that the High Altitude Water Cherenkov Gamma-ray (HAWC) collaboration...

This year, DESY and European XFEL Users’ Meetings have bust out of its usual auditorium setting and instead made its way to the huge tents of the ‘Hamburg Kuppel’ across the street from DESY. With more than 1100 registered attendees, the Users’ Meetings are taking advantage of this special event venue. On the agenda, under the title of “Research with Synchrotron Radiation and FELs”,...

The DESYUM building now nearly has a complete skeleton: today, the building that will contain the DESY research centre’s visitor centre hosted its topping out ceremony. Since its foundation stone was set in place in May 2023, six storeys have risen above the entry rotunda near the research centre’s Notkestraße entrance in Hamburg. The DESYUM building’s 3250 square metres of usable space will host...

A research team from DESY and the University of Jena has for the first time demonstrated live the formation of the mineral stishovite (a form of silicon dioxide or silica, SiO2), which is often used as a mineral to detect ancient asteroid and meteorite impacts on the Earth's surface. The researchers observed the formation of the mineral using time-resolved X-ray diffraction experiments at DESY's...

A research team from Stockholm University, in collaboration with DESY and the Montanuniversität Leoben in Austria, has succeeded for the first time in investigating the surface of iron and ruthenium catalysts in the formation of ammonia from nitrogen and hydrogen; the results have been published in the scientific journal Nature. With exact knowledge of how these catalysts work, it may be possible to identify...

DESY leading scientist Dr. Holger Sondermann has taken over as the new Scientific Director of the Centre for Structural Systems Biology (CSSB) for the coming two years. The CSSB, located on the DESY campus in Hamburg, is one of the campus’ core cooperative institutes involving DESY and eight other universities and research centres. On 1 December 2023, the CSSB Council confirmed the CSSB Directorate’s...

Anne L´Huillier from the University of Lund has visited the research centre DESY on Friday. The physicist, who won the 2023 Nobel Prize in Physics together with two colleagues for the experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter, visited DESY´s Hamburg site and the Center for Free-Electron Laser Science CFEL at the invitation of Francesca...

An international team of researchers led by Mungo Frost from SLAC National Accelerator Laboratory in California and including DESY scientists used the European X-ray free electron laser (XFEL) in Schenefeld to gain new insights into the formation and occurrence of diamond rain in ice giants such as Neptune, Uranus, or exoplanets outside of our solar system. The results, which have now been published in...

An experiment led by a team of DESY and Universität Hamburg scientists has discovered that gold nanoparticles can move through liquid biological matter faster than expected when coated by the polymer polyethylene glycol (PEG). The team’s data, which were acquired using X-ray photon correlation spectroscopy, reveal both the structure and the dynamics of the nanoparticles in various biological fluids with high temporal resolution. The...
