The Cosmic Microwave Background (CMB) contains key information about the earliest stages of the Universe's evolution. In a recent study, astrophysicists from the National Centre for Nuclear Research (NCBJ) investigated how microwave emission from our Galaxy and gravitational lensing distort the CMB signal. They also examined which methods could be employed by future CMB experiments to place tighter constraints on the amplitude of primordial gravitational waves.

Researchers from the NOMATEN Center of Excellence at the National Center for Nuclear Research and CEA Paris-Saclay have developed a multiscale method for determining the mobility of radiation defects induced by ionizing radiation. This new approach combines numerical simulations, hydrodynamics, and experimental data, and serves as a new tool for determining the behavior of materials exposed to radiation, such as in nuclear reactors.

X-shaped radio galaxies (XRGs) are a rare class of active galaxies, whose origins are still uncertain. Scientists believe they might be linked to galaxy mergers, which makes them candidates to find black hole pairs that will produce gravitational waves in the future. Results of the study of almost 200 XRGs, led by Prajnadipt Ghosh, a doctoral student from the Astrophysics Division at NCBJ, have just been published in the Astrophysical Journal.

Lead-208 is one of the most studied and best understood nuclei. However, there remain a few mysteries concerning its structure. In their most recent paper, scientists from the Nuclear Physics Division at NCBJ proposed a solution to a half a century old question concerning the strength of the transition from the first 2+ excited state of 208Pb to its ground state.

Electronics based on gallium nitride (GaN) can be significantly more resistant to radiation-induced defects than silicon-based solutions. This makes it a good candidate for use in extreme conditions, such as in nuclear reactors or space missions. To better understand the behaviour of gallium nitride under the influence of radiation, a team of scientists from the National Centre for Nuclear Research, the Institute of High Pressure Physics of the Polish Academy of Sciences and the University of Lisbon investigated the mechanisms of defect formation depending on the fabrication method and the polarity of GaN crystals.

The National Centre for Nuclear Research has joined the patrons of the Wrocław Bridge – Energy and Industry Dialogue 2026 Congress, organised by DISE ENERGY. At the same time, the Programme Council has begun its work on preparing the agenda for this year’s event, which will be held under the theme “Energy in times of uncertainty”. The Council includes Prof. Jakub Kupecki, Director of the NCBJ. The Council comprises a group of experts and leaders from the energy sector, business and public administration.

The Polish team, which included specialists from the National Centre for Nuclear Research, came second in the final of the “CISPA European Cybersecurity & AI Hackathon Championship”. The team qualified for the final as one of the 18 highest-ranked teams from the regional rounds across Europe.

As of 1 July 2026, former Vice Chairman Ryszard Sobierajski is the new Chairman of the European XFEL Council. Professor Sobierajski has been collaborating with the National Centre for Nuclear Research (NCBJ) for many years as part of the consortium implementing the "Support for Polish EuXFEL Users" project.

A new era of astronomy and astrophysics begins, as the NSF-DOE Vera C. Rubin Observatory launches LSST, the most comprehensive cinematic record of the Universe. The initiative involves a Polish consortium composed of eight institutions, led by the National Centre for Nuclear Research.

The research results were presented on June 25, 2026, at Neutrino 2026: XXXII International Conference on Neutrino Physics and Astrophysics, held at the University of California, Irvine, USA. There are currently eight representatives from Poland working at Super-K, including researchers from the National Centre for Nuclear Research.
