Janfest 2022: Wheel of Star Formation — A conference dedicated to Prof. Jan Palouš
12. Sep 2022 - 16. Sep 2022 • Prag, Tschechische Republik
Zusammenfassung:
In light of the COVID-19 outbreak, we decided to postpone the Wheel of Star Formation conference that was originally planned to take place in Prague in September 2020.

The Physics of Galaxies research group is a part of the Galaxies and Planetary Systems department of the Astronomical Institute of the Czech Academy of Sciences. Our studies use our own observations spanning radio, millimetre and optical wavelengths from the VLA, Arecibo, ALMA and various ESO telescopes, complemented with existing archival data. We also perform numerical N-body and hydrodynamical simulations using the facilities of the Astronomical Institute and on supercomputers elsewhere.

CSS 2022 — Cosmology on Small Scales 2022: Dark Energy and the Local Hubble Expansion Problem
21. Sep 2022 - 24. Sep 2022 • Prag, Tschechische Republik
Veranstalter:
Institute of Mathematics, Czech Academy of Sciences
Zusammenfassung:
One hundred years ago, Russian mathematician and physicist Alexander A. Friedmann applied the system of Einstein equations to the hypersphere with a time varying radius. In this way, he obtained a nonlinear ordinary differential equation which is called the Friedmann equation after him and serves now as a cornerstone of the standard cosmological model. Unfortunately, it is well known that this model exhibits a number of paradoxes. The main goal of the CSS 2022 conference is to discuss whether and how the Friedmann equation can be applied at various spatial scales, from our local cosmic neighborhood up to the whole Universe; and if the existence of dark matter and dark energy are merely artifacts of excessive extrapolations. So, it is timely to gather specialists from various branches of astronomy and astrophysics to discuss these issues.
