Barely visible galaxies are the key to understanding the Universe

When we look at the night sky, we cannot free ourselves from questions. We wonder if it is possible to count the stars. We imagine how great a distance separates us from them. When we realize what a light year actually is, we are surprised to discover that we are actually looking into the further or closer past. Scientists from the National Center for Nuclear Research experience a similar fascination, looking for answers to these and other questions about how the Universe looks and works. In the coming years, this search will be able to be more effective thanks to the project „ Barely visible: low surface brightness galaxies in the LSST era” under the supervision of Prof. dr hab. Agnieszka Pollo financed by the National Science Center under the MAESTRO program.

Smashing galaxies into dust

Dr William James Pearson will investigate how we can more reliably identify galaxy mergers using their morphologies and how mergers influence their dust content, dust attenuation, and metallicity. This will be done by combining artificial intelligence (AI) with more traditional methods to detect galaxy mergers as well as use state of the art. observations and techniques to study the galaxies’ dust and metal. Exploration of this fascinating topic will be possible thanks to a grant from the National Science Center under the SONATA programme.

NCBJ scientists elected as members of the Astronomy Committee of the Polish Academy of Sciences

On 14 May, nominations for members of the Committee on Astronomy of the Polish Academy of Sciences for the term 2024-2027 were announced. Among the members were scientists from the NCBJ's Astrophysics Division. Prof Katarzyna Małek was also elected to the Presidium of the Committee.

Uchwycony w świetle podczerwonym przez Kosmiczny Teleskop Jamesa Webba, obraz ten po raz pierwszy ujawnia niewidoczne wcześniej obszary narodzin gwiazd. Źródło: NASA, ESA, CSA, STScI

Can dust evaporate in harsh interstellar environments?

Dust represents an important component of the interstellar medium of galaxies and is involved in various physical processes. As a consequence, it is crucial to understand the factors that influence its formation and destruction. In a recent study, a team of scientists led by dr Ambra Nanni of the NCBJ’s Astrophysics Division analysed the effect of photo-evaporation on the survival of dust in the interstellar medium of galaxies.

In the Universe, appearance matters: Dusty shapes of colourful galaxies

Can we see what is hidden in a cloud of dust without the aid of infrared vision? Scientists involved in the largest optical survey of the sky this decade, the Legacy Survey of Space and Time (LSST), led by a group from the NCBJ’s Astrophysics Division, in a paper published in April in Astronomy & Astrophysics, propose a novel method to extract information about dust in galaxies without actually observing its infrared light.

New observations of the outer Milky Way help to understand the star formation process

Having an accurate understanding of the star formation process is essential to comprehend the formation and evolution of galaxies, and this requires to unveil the impact of environment on star formation. In a new study published in Monthly Notices of the Royal Astronomical Society, scientists used a new survey of the outer Galaxy to refine the distance and properties of star-forming clumps and study how star formation behave in comparison with the inner Galaxy.
