26. From Radio Transients to Compact AGNs: Exploring the Earliest Phases of Radio Activity

Prof. Magdalena Kunert-Bajraszewska (NCU)

7.07.2026, 11:10

Our research focuses on the earliest stages of radio activity in active galactic nuclei (AGN), combining time-domain studies of radio transients with low-frequency imaging of compact radio sources. Using multiwavelength observations, we investigate the physical mechanisms responsible for triggering radio jets, their early evolution, and their interaction with the surrounding interstellar...

27. From the Star-Forming Main Sequence to Galaxy Growth: A Continuity-Equation View of Stellar-Mass Evolution in JWST COSMOS-Web

Prof. Maciej Koprowski (NCU)

7.07.2026, 11:30

The star-forming main sequence provides a compact description of how galaxies build their stellar mass as a function of cosmic time. In this talk, I will present a continuity-equation framework for translating an observed redshift-dependent star-forming main sequence into the predicted evolution of the galaxy stellar mass function. Starting from observed high-redshift stellar mass functions,...

28. Understanding Small Planets: Paving the Path from Kepler/K2 and TESS to PLATO

Dr Grzegorz Nowak (NCU)

7.07.2026, 11:50

In this talk, I will present selected results from radial velocity (RV) follow-up campaigns of small transiting planets (1–4 Earth radii) discovered by Kepler/K2 and TESS. These observations were conducted using the TNG/HARPS-N, ESO/HARPS, CAHA/CARMENES, and VLT/ESPRESSO instruments within the framework of the KESPRINT, THIRSTEE, and CARMENES consortia. Precise RV measurements are essential...

29. Exoplanets from Toruń: past, present and future.

Prof. Andrzej Niedzielski (NCU)

7.07.2026, 12:10

I will present our exoplanet search project, that resulted in detection of 30 exoplanets, mostly around evolved stars, so far. I will briefly present status of the project, our forthcoming results as well as our plans for the future.
