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.

Gas on the run – ALMA spots the shadow of a molecular outflow from a quasar when the Universe was less than one billion years old

Theoretical predictions have been confirmed with the discovery of an outflow of molecular gas from a quasar when the Universe was less than a billion years old. The results obtained from the observations of the ALMA telescope are of great importance for understanding the processes of star formation in galaxies. Dr. Darko Donevski from the NCBJ Astrophysics Division participated in the work of the research team.

Midlife Crisis of the Universe: Galaxies’ interactions did not affect interstellar dust

A new study has shed light on the intricate cosmic dance between interstellar dust in galaxies, properties of galaxies, and their environments. For a very long time, the relations between dust and the galaxies was investigated. However, the link between dust properties and the neighborhood of galaxies was poorly understood. In the newest work published in Astronomy&Astrophysics, the scientists studied the relationship between the amount of stellar light absorbed by dust, and the environments of galaxies.

Professor Agnieszka Pollo has taken the position of Deputy Director for Science at NCBJ

On October 16, 2023, a change took place in the position of Deputy Director for Science at NCBJ. The former director, Professor Ewa Rondio, passed on her duties to Professor Agnieszka Pollo, an astrophysicist who has been successfully leading the rapidly developing Department of Astrophysics.

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
