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)

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.

Obrazy radiowe młodego Wszechświata

Międzynarodowy zespół astronomów, w którego składzie znajdują się także naukowcy z Polski, opublikował w czasopiśmie "Astronomy and Astrophysics" najdokładniejszą w historii mapę Wszechświata w zakresie niskich częstotliwości radiowych. Mapę stworzono dzięki europejskiej sieci odbiorników LOFAR. Naukowcy wykryli m.in. słabe poświaty radiowe od gwiazd, które eksplodowały jako supernowe w dziesiątkach tysięcy galaktyk.

Gravitational signals can help measure the viscosity of dark matter in the future

If gravitational waves traveled through a medium filled with sticky dark matter, then the wave amplitude would be (weakly) damped. The analysis of this effect could shed new light on the nature of dark matter - argues Prof. Marek Biesiada (NCBJ) together with Chinese colleagues in a work published in the MNRAS Letters journal.

Giant hidden black hole discovered in the early universe

An international team of astrophysicists has discovered a giant black hole hidden among dust in a galaxy that already existed 1.4 billion years after the Big Bang. This is one of the first results of a project called Herschel Extragalactic Legacy Project (HELP). The lead co-author of the work is dr hab. Katarzyna Małek from the NCBJ Astrophysics Department.

A starry sky made of more than 25,000 supermassive black holes

The map published in the journal Astronomy & Astrophysics reveals more than 25,000 active supermassive black holes in distant galaxies. It is the result of a survey of the sky carried out over radio frequencies. Dr hab. Katarzyna Małek from the NCBJ Astrophysics Division participated in the preparation of the work.
