Overview

Scientific discussion meeting organised by Professor James Binney FRS, Dr Roya Mohayaee, Professor John Peacock FRS and Professor Subir Sarkar.

Is the universe simple enough to be adequately described by the standard ΛCDM cosmological model which assumes the isotropic and homogeneous Friedmann-Lemaître-Robertson-Walker metric? Tensions have emerged between the values of cosmological parameters estimated in different ways. Do these tensions signal that our model is too simple? Could a more sophisticated model account for the data without invoking a Cosmological Constant?

The schedule of talks and speaker biographies are available below. Speaker abstracts will be available closer to the meeting date. Meeting papers will be published in a future issue of Philosophical Transactions of the Royal Society A.

Poster session

There will be a poster session on Monday 15 April. If you would like to apply to present a poster please submit your proposed title, abstract (not more than 200 words and in third person), author list, name of the proposed presenter and institution to the Scientific Programmes team no later than Monday 4 March. Please include the text ‘Poster abstract submission’ in the email subject line. Please note that places are limited and posters are selected at the scientific organisers’ discretion.
