The McChasy code aids in the study of defects in semiconductors for special applications.

Defects in the crystal structure of semiconductors used in space and nuclear industry can have an impact on the functioning of devices built with them. A master's student from Instituto Superior Técnico in Portugal, in collaboration with NCBJ scientists, investigated defects that arise in gallium nitride when bombarded with argon. The use of the McChasy computer program developed in Świerk was a crucial aspect of the research. ----

Midlife Crisis of the Universe: Galaxies’ interactions did not affect interstellar dust

Dust-related energy Budget of over 1000 galaxies at the midlife of the Universe. Arrows correspond to the correlations with different quantities. M* is stellar mass, age* is stellar age. Different lines correspond to different relations from the literature.  is the ultraviolet slope, a proxy for dust attenuation. IRX is the ratio of infrared to ultraviolet luminosities.
A new study has shed light on the intricate cosmic dance between interstellar dust in galaxies, properties of galaxies, and their environments. For a very long time, the relations between dust and the galaxies was investigated. However, the link between dust properties and the neighborhood of galaxies was poorly understood. In the newest work published in Astronomy&Astrophysics, the scientists studied the relationship between the amount of stellar light absorbed by dust, and the environments of galaxies. ----

The team of researchers from France, Poland, and the United Kingdom has proposed a new hypothesis suggesting that interactions between dark matter and neutrinos could shed light on certain anomalies in the distribution of the cosmic microwave background radiation. The details of the analysis have been described in articles published in the prestigious scientific journals, Monthly Notices of the Royal Astronomical Society: Letters and Physics of the Dark Universe. ----

Wacław Gudowski from the Department of Nuclear Energy and Environmental Analysis of NCBJ received the Eagle "Wprost" award in the "Business and science" category. The award was granted for outstanding scientific achievements and teaching activities in the field of nuclear energy, as well as for involvement in the development of scientific cooperation between Poland and Sweden. ----

HTGR-POLA research reactor presented during the 67th IAEA General Conference

The conceptual design of the Polish high-temperature gas-cooled reactor (HTGR-POLA), presented in June in Warsaw, was presented last week (September 27) at the international nuclear forum, at the annual general conference of the International Atomic Energy Agency in Vienna. ----

NRC delegation visit

On September 26, 2023, NCBJ was visited by Mr. David Austin Wright, Commissioner of the NRC - the American Nuclear Regulatory Commission. The guest was accompanied by representatives of the Commission and the US Embassy in Warsaw, including the deputy head of mission, Mr. Daniel J. Lawton. The guests met with the Institute's management, learned information about our main research priorities and visited the MARIA reactor. ----
