MMWW2019 — Multimessenger Winter Workshop @ Prague
04. Dez 2019 - 07. Dez 2019 • Prag, Tschechische Republik
Zusammenfassung:
The aim of this workshop is to bring together theorists and observers working on the broad topic of multi-messenger astronomy and astrophysics. The focus will be on how to best access and test fundamental physics by observing compact objects, taking advantage of current and future data. The workshop will connect experts from disjoint but related fields and the format will provide ample time for informal interaction and discussion.The list of topics includes compact objects in General Relativity and beyond, gravitational waves obsevations and theory, pulsar timing, accretion physics, and multimessenger tests of fundamental physics and cosmology, from both data and theory perspectives. The workshop is by invitation only.

CSS 2020 — Cosmology on Small Scales 2020: Excessive Extrapolations and Selected Controversies in Cosmology
23. Sep 2020 - 26. Sep 2020 • Prag, Tschechische Republik
Veranstalter:
Institute of Mathematics, Czech Academy of Sciences
Zusammenfassung:
According to the modern cosmological paradigm, about 2/3 of the energy of the Universe is in the dark form and about 5/6 of the matter is invisible. However, numerous recent attempts to detect independently the dark-matter particles failed, and a number of other problems with the existence of dark energy and dark matter (such as the anomalous friction in the dark-matter halos of galaxies, etc.) become now more and more obvious. All these troubles raise the question if the "dark" substance is merely a result of excessive extrapolations involved in the theoretical analysis? So, it is timely to gather specialists from various branches of astronomy and astrophysics to discuss these issues.
Themen:
Mathematical aspects of the extrapolations used in cosmology, Arguments for and against dark matter, and revisiting the foundations of physics, Alternative models for dark matter and dark energy, A systematic discord in the value of the Hubble constant derived by different methods, Theoretical possibility and observational evidence for small-scale cosmological effects, Complementary redshifts of non-cosmological nature, Quantum effects on the early universe and their observational imprints at the present time
