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.
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.
POLAR-2 at the POLSA conference
W dniach 23-24 listopada odbędzie się konferencja „O Lemie i kosmosie” organizowana przez Polską Agencję Kosmiczną POLSA. Dr Adam Zadrożny oraz mgr inż. Dominik Rybka – naukowcy z Narodowego Centrum Badań Jądrowych, będą mówić na niej o międzynarodowym projekcie POLAR-2 i polskim wkładzie w tę misję.
LIGO and Virgo extend the catalog of gravitational waves
In the data from the third observatory campaign of Advanced-LIGO and Advanced-Virgo observatories (from November 2019 to March 2020), another 35 sources of gravitational waves were found, thus extending their list to 90 objects. 32 sources come from the merger of two black holes, and 3 from the merger of the black hole system with a neutron star. Scientists from the NCBJ Astrophysics Department are participating in the work of the LVK consortium.
Dark Matter Day
Serdecznie zapraszamy do wzięcia udziału w tegorocznym spotkaniu online, które odbędzie się 28 października i wysłuchania wykładów popularnonaukowych na temat ciemnej materii przygotowanych m. in. przez pracowników NCBJ.
HELP – a modern and standardized catalog of extra-galactic objects
An international team of scientists has provided scientists and enthusiasts with the most complete catalog of extragalactic objects to date, covering an area of over 3% of the full angle of the sky’s solid and containing 170 million sources. The modeling of their energy spectra was the responsibility of Ph. D. Katarzyna Małek from the NCBJ Astrophysics Department.
