Our Research

The fourth division (BP4) of The Fundamental Research Department (Departament Badań Podstawowych) deals with research in astrophysics and astronomy, mainly their observational aspects. The BP4 division is located in Warsaw at 7 Pasteura street.

The research conducted at the Astrophysics Laboratory includes:

  • Cosmology: CMB, large structures of the Universe, dark matter, non-standard cosmology and gravitational lensing
  • Gravitational waves: Multi-messenger astronomy, new tools for cosmology
  • Physics of galaxies: Formation and evolution of galaxies, AGN, quasars and gamma-ray burst
  • Interstellar medium: Star formation, neutron stars and white dwarfs
Check our Research Fields page for more information.


The BP4 division is also involved in several international projects. Check our Scientific Projects page for more information.

VISTULA Workshop

The workshop is organized as part of the project CLEVER: Cosmology & GaLaxy EVolution In The New ObsErving ProgRammes. Project founded by the Strategic Partnership project BPI/PST/2024/1/00019 by NAWA – Polish National Agency For Academic Exchange.

The rationale

Machine learning and modern statistical methods are becoming central tools in astrophysics and cosmology, from survey data reduction and photometric redshifts to time‑domain discovery, image classification and parameter inference. This workshop offers a structured introduction to statistical foundations and machine learning concepts.

The goal of this workshop is to provide a structured, beginner‑friendly entry point to machine learning and advanced statistics in astrophysics, while progressively reaching more advanced topics. The format will combine morning lectures with afternoon hands‑on sessions in which participants work through concrete astrophysical use cases under the guidance of the invited speakers and local tutors.

The workshop is aimed at Master’s students, early‑stage PhD students and junior researchers from NCBJ, the University of Warsaw, and the CLEVER partner institutions. It will explicitly welcome participants with limited prior exposure to machine learning, provided they are comfortable with basic programming (e.g. Python) and standard statistical concepts. By the end of the workshop, participants should be able to: understand the main families of machine learning methods used in current astrophysical research; critically assess when a machine‑learning approach is appropriate; implement and evaluate simple models on real data; and recognise common pitfalls such as overfitting, data leakage and biased training sets.

The invited speakers span a broad range of applications including galaxy formation and evolution, large‑scale surveys, time‑domain and transient astronomy, exoplanets and cosmology.

Hosted in Warsaw as part of the CLEVER-NAWA partnership , the workshop will strengthen training and collaboration across the network by bringing together students, junior researchers, and invited experts for a hands-on introduction to machine learning and advanced statistics in astrophysics.

Invited speakers: 

  • Ting-Yun Cheng (Kapteyn Astronomical Institute in Groningen)
  • Antonio La Marca (Leiden Observatory, European Space Agency)
  • Alex Razim (Centre for Astrophysics and Cosmology, Nova Gorica)
  • Carlo Schimd (Laboratoire d’Astrophysique de Marseille)
  • Will J. Pearson (National Centre for Nuclear Research)

NCBJ astrophysicists advance understanding of distortions in the Cosmic Microwave Background

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.

Are cosmic butterflies hiding the binary supermassive black holes?

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.

Largest Ever Radio Sky Survey Maps the Universe in Unprecedented Detail

An international collaboration using the Low Frequency Array (LOFAR) has unveiled an exceptionally detailed radio sky map, revealing 13.7 million cosmic sources and delivering the most complete census yet of actively growing supermassive black holes. It showcases an extraordinary variety of systems powered by these black holes, whose radio emission can extend for millions of light-years. The newly released LOFAR Two-metre Sky Survey (LoTSS-DR3) marks a major milestone in radio astronomy and international scientific collaboration. The result is published in Astronomy & Astrophysics.

Ilustracja pokazująca ukrytą różnorodność nieaktywnych galaktyk: Chociaż galaktyki wygaszone wydają się podobnie czerwone i stare w świetle gwiazd obserwowanym przez JWST (dół) , obrazy ALMA pokazują, że zawartość zimnego pyłu i gazu molekularnego może się znacznie różnić. Niektóre obiekty zachowują znaczne zasoby pyłu i gazu (po lewej), podczas gdy inne są prawie wyczerpane (po prawej), co wskazuje na różnorodne ścieżki ewolucyjne po zakończeniu formowania się gwiazd
