The Dundee Astronomical Society was formed in 1956 and is affiliated to the British Astronomical Association BAA (to whom we send observations). In addition the Society has a number of honorary members throughout the country.
We would normally hold member meetings once or twice a month at the Mills Observatory, Balgay Hill, Dundee in the months October through to March. The first part of the meeting consists of a talk lasting about an hour from a guest or member, followed by a short tea break, then a shorter session for members to make their contributions.
The Society has a healthy membership and welcomes new members. Please contact our Secretary for further information via the Links page.
All Friday meetings begin at 7:30pm at the Mills Observatory unless otherwise stated, members should arrive by 7:15 to ensure the talk starts on time. Thanks
Next Meeting Friday 13th February
Hong-Gang Yang, Edinburgh University – Galaxy Assembly Bias and Its Role in Cosmology.
Over the past few decades, our picture of the Universe has converged on the so-called ΛCDM model—where Λ represents a constant dark energy and CDM stands for cold dark matter. This model has been remarkably successful in explaining a wide range of observations, from the cosmic microwave background (CMB) to the large-scale distribution of galaxies. Yet, important puzzles remain. For example, the value of the Hubble constant inferred from the CMB does not agree with the one measured from nearby galaxies, and recent results from the DESI Collaboration even suggest that dark energy may not be constant but evolving over time. These tensions remind us that our current model, while powerful, is not the final word on cosmology.
