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)

Awards of the Director of DBP NCBJ for scientific achievements in 2021

On June 27, the Awards of the Director of the Fundamental Research Department of NCBJ were presented for scientific achievements and popularizing activities for 2021. This year, the following were awarded: PhD. Varvara Batozskaya from the Department of High Energy Physics, prof. Marek Biesiada from the Department of Astrophysics, professors Michał Kowal and Janusz Skalski from the Department of Theoretical Physics and prof. Katarzyna Małek from the Department of Astrophysics for achievements in the area of ​​popularization.

How heavy can a graviton be?

Scientists are trying to determine the properties of the graviton – the hypothetical particle that carries the gravitational force. In a study published in the Journal of High Energy Astrophysics, based on the analysis of 12 galaxy clusters, prof. Marek Biesiada and his colleagues presented a new limit on the mass of graviton. It is seven orders of magnitude stronger than the limitations of observing gravitational waves.

Influence of gravitational darkening on the spectrum of rotating objects

Exotic, rapidly rotating objects are of interest to astrophysicists. Polish astronomers are trying to obtain information about the physical conditions inside fast-rotating neutron stars. In a work published in The Astronomical Journal, they enriched the analysis with effects resulting from the phenomenon of gravitational darkening.

The history of the quasar HE 0435-5304 – the distance matters!

Publicly available data is not too popular among scientific breakthrough seekers. Usually they were extensively researched and there is nothing more to discover. However, there are exceptions, such as the quasar HE 0435-5304, which sounds boring by name.

Searching for the gravitationally lensed glow of gamma-ray bursts

NCBJ participates in the study of gamma-ray bursts (GRBs), in particular the gravitational lensing of their glow. GRBs are one of the most energetic processes in the universe.Scientists propose to extend the search for GRBs with multi-range observations of the glow of these phenomena.
