Workshop in Cosmology
Challenges to ΛCDM
Thessaloniki, Greece, September 4-7, 2022
Topic, Aim & Location
Recent observations have triggered extensive discussions among the cosmological community, with potentially pivotal and far reaching implications. The catalyst for the ongoing debate appears to be so far unexplained differences between the early and the late-time measurements of the Hubble constant. Persistent reports of bulk peculiar motions larger and faster than it is typically anticipated, as well as repeated claims of anomalous dipolar anisotropies in the number counts of distant radio-sources have added to the debate. As a result, an increasing number of cosmologists are reconsidering the status of the current cosmological paradigm. In summary, it seems conceivable that the time may have come to review some of our long-standing views and perceptions regarding the universe we live in.
The aim of the workshop is to review the status of the current cosmological model, the ΛCDM paradigm, draw attention to open issues that may question its foundations and robustness, as well as discuss possible solutions and alternatives.
The meeting is organised by the Cosmology Group in the Astronomy Lab of the Aristotle University of Thessaloniki and the venue is within the university campus near the city center. The workshop and the accompanying events are funded by the Hellenic Foundation for Research and Innovation, under the three-year research project ``Tilted Cosmology''.
