30. Cosmic ray-driven dynamo, galactic winds and synchrotron radio-emission of Milky Way-type galaxies.

Prof. Michał Hanasz (NCU)

A case of the successful Polish-German collaboration in theoretical astrophysics.

Recent studies of the magnetized interstellar medium indicate that cosmic rays accelerated in supernova remnants play a crucial role in driving galactic winds and amplifying galactic magnetic fields. Cosmic rays have a strong dynamical impact on the interstellar medium.

31. Hunting for stellar-mass black holes: spectroscopic classification of microlensing events and other transients.

Dr Paweł Zieliński (NCU)

Sky surveys, like Gaia, ZTF, OGLE, ASAS-SN and recent LSST, continuously monitor the sky, detecting various transient phenomena such as gravitational microlensing events that can reveal compact objects, including isolated stellar-mass black holes, neutron stars or white dwarfs. Combining photometric, spectroscopic and astrometric data with intensive ground-based follow-up is essential for...

32. Towards an accurate inhomogeneous model of the Universe

Prof. Boud Roukema (NCU)

The current standard cosmological model, the LCDM model,replaced the more rough big bang model in the 1990s. This model is precise, but is rejected by the lack of structure above the 10 Gpc/h scale, by the local few hundred megaparsec measurements of the expansion rate, and by the dipole in the 1 Gpc/h scale galaxy distribution. Using the upcoming surveys on Rubin/LSST and 4MOST, the UMK...
