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)

Galactic outflows drive the evolution of dwarf galaxies

Stellar feedback is expected to play a key role in regulating the evolution of low-mass galaxies by producing galactic-scale winds (also known as outflows) that push the gas away from the interstellar medium, eventually preventing from the formation of new stars. In this respect, an international team of astronomers led by NCBJ scientist, have published a work on the Astronomy & Astrophysics journal addressing the impact of galactic outflows on the baryonic cycle of nearby dwarf galaxies

Annual Awards Presented by the Fundamental Research Department of NCBJ

On June 26, 2023, a Special Colloquium was held, during which awards were presented for the best research and popularization activities in 2022 at the Fundamental Research Department. The winners were Prof. Michał Bluj, a team consisting of Prof. Paweł Ziń and Dr. Maciej Pylak, Dr. Michael Romano, and Prof. Jerzy Kowalski-Glikman and Dr. Miguel Figueira

Unveiling the hidden stars: ALMA Shines a Light on Dust Attenuation

Interstellar dust is a key component in galaxies. It favors star formation and drives the chemistry and physics of the interstellar medium. However, it hides the majority of stars in a way that it is impossible to observe them. Astrophysicists use dust attenuation laws that would uncover these hidden stars by reverse-engineering the light from galaxies to quantify how many stars are there.

The project of a PhD student of the NCBJ Department of Astrophysics qualified for the „Pearls of Science” program

The first edition of the competition under the „Pearls of Science” program has been settled. One of the scientists qualified for the program is Krzysztof Lisiecki, MSc, a PhD student at the Astrophysics Department of the National Center for Nuclear Research, conducting research in the project „In search of witnesses to the early Universe – studying the properties of red nuggets”.

New images of tens of thousands of galaxies have been made available at the Galactic Zoo

Twenty thousand high quality images from the Hawaii Two-0 (H20)/Cosmic Dawn survey have been released to the public on the most popular citizen science project: Galaxy Zoo. Anyone in the world can become a citizen scientist and help astronomers classify images from the Subaru telescope.

Soczewkowane obrazy rozbłysku gamma mogą dochodzić do obserwatora po drogach o różnej długości (A, B). Jeśli fotony o różnych energiach podróżują z tą samą prędkością, opóźnienia między tymi samymi zmianami w wyglądzie obrazów A' i B' nie będą zależały od energii fotonów. Jeśli dla fotonów o większych energiach opóźnienie się zmieni, będzie to świadczyło, że poruszają się one z nieco inną prędkością niż fotony o mniejszych energiach. (Źródło: NCBJ)

Wyścigi fotonów pod lupą grawitacji

Fotony przemierzają Wszechświat z niezmienną prędkością. Tylko czy zawsze wszystkie z tą samą? Aby sprawdzić, czy potencjalne efekty kwantowej grawitacji nie wpływają na prędkości fotonów o bardzo dużych energiach, polsko-chiński zespół naukowców zaprzągł do pracy dwa spektakularne zjawiska kosmiczne: soczewki grawitacyjne i wybuchy promieniowania gamma.
