The MARIA reactor has quickly filled the gap in the global supply of life-saving radioisotopes

Rdzeń reaktora badawczego Maria w NCBJ
The Polish nuclear reactor MARIA was able to rapidly rearrange its work schedule to respond to the shortages of medical molybdenum-99 due to a fault in the Dutch HFR reactor. Molybdenum-99 is a radionuclide widely applied in nuclear medicine to save human life.   ----

The memory of the late prof. Maria "Hula" Szeptycka

Prof. Maria "Hula" Szeptycka
"It was important to understand exactly what and why you were doing something, all questions were allowed, but you had to be able to defend your results and the methods used." This is how Prof. Ewa Rondio recalls the collaboration with Prof. Maria Szeptycka. ----

The NCBJ and IChTJ Graduate School gains a new look thanks to participation in the STER program

Logo programu STER - Umiędzynarodowienie Szkół Doktorskich
For the next 3 years, the NCBJ (National Centre for Nuclear Research) and IChTJ (Institute of Nuclear Chemistry and Technology) Graduate School of Physics and Chemistry will participate in the STER program – Internationalization of Doctoral Schools by NAWA. This will allow young scientists from around the world to gain education and conduct research in cooperation with the best research centers. ----

How do you weigh galaxies for the greatest sky surveys?

Koncepcja artystyczna teleskopu LSST wewnątrz jego kopuły. LSST przeprowadzi głębokie, dziesięcioletnie badanie obrazowe w sześciu szerokich pasmach optycznych na głównym obszarze badania 18 000 stopni kwadratowych.
NCBJ coordinates Polish participation in the largest observational astronomy project in history. The field of view of a telescope built in Chile will cover an area 40 times larger than the Moon’s disc. The observations planned for 10 years will provide, among others data about variable objects. Scientists from NCBJ working as part of the ASTROdust team are already preparing algorithms that will enrich the set of information obtained from the observations. ----

New educational projects addressed to students and enthusiasts

Detektory DEiS: Cosmic Watch i licznik Geigera-Müllera
In the coming year, we plan to invite everyone to the Open Door Days in Świerk. This time, however, we will open these doors virtually, thanks to which we will show more and everyone willing. We will also extend the campaign of lending detectors to schools that enable them to conduct lessons on radiation. ----

A new method of determining distances in the universe uses quasars

Astronomers use many methods of determining the distance to celestial bodies, but each of them has limits of its applicability. An international group of scientists, with the participation of Professor Marek Biesiada from the National Center for Nuclear Research, proposes the use of quasars for this purpose. The method could be applied to objects whose image reaches us even 13 billion years ago.   ----

The past to the future, or how physicists study the functioning of the first Homo Sapiens cultures

The end of the year is a good time in research institutions to recall the particularly interesting results achieved in the previous twelve months. These undoubtedly include those that are the result of collaboration between scientists of various specialties. Their example is the joint work of archaeologists, chemists and physicists on the archaeological site in Ćmielów, published last year. ----

Gravitational waves allow us to test the General Theory of Relativity

Based on the latest research results from the LIGO / Virgo gravitational wave observatories, scientists conducted tests of General Relativity (GRT). Nine different methods were used to verify the consistency of Einstein’s theory with the observational data. No discrepancies were found. Polish scientists from the Polgraw group, including scientists from NCBJ, participated in the research. ----
