03/2019: ATOM Festival

There will be no talk by the ATOM Society in March, but members are invited to attend the Atom Festival of Science and Technology 2019. See http://www.atomfestival.org.UK/ for more information.

Members will be able to attend the talk on the evening of March 22. They will have to book the tickets through the festival web page, but will receive a booking code for a complementary ticket from the secretary on request.

01/2019: Galaxies & Black Holes (R. Davies)

Place and Time: Abingdon, Thursday 17 January 2019 from 19:00 for 19:30

King Charles Room, King’s Head and Bell, (10 E St Helen St, Abingdon OX14 5EA)

TITLE: Galaxies & Black Holes

Using Hubble Space Telescope and giant ground based telescopes we have discovered supermassive black holes, with masses ranging from millions to billions times the mass of the Sun, at the very centre of massive galaxies. In this talk I will show how we measure the masses black holes and go on to reveal the close relationship between black holes and the evolution of the galaxies that host them. In exploring this question we will discover an unexpected twist in the story of galaxy evolution.

Speaker:  Roger Davies

Roger Davies is the Philip Wetton Professor and Director of the Hintze Centre for Astrophysical Surveys at the University of Oxford and a fellow of Christ Church.

He grew up in an industrial town in the north of England attending the local grammar school and going on to read Physics at University College London. He started research working on galaxy dynamics in Cambridge in the 1970s after which he moved to California before spending 6 years on the staff of the US National Observatory in Tucson, Arizona. As part of the “7 Samurai” team he worked out a new way of measuring the distances to galaxies and discovered the “Great Attractor”, a huge concentration of galaxy clusters in the southern sky. He moved to Oxford in 1988 to lead the UK’s participation in the construction of the 8m Gemini telescopes, in Hawaii and Chile. In 1994 he took up the post of Professor of Astronomy at Durham University returning to Oxford in 2002 where he was Head of the Physics Department from 2005-10. He is the founding Director of the Hintze Centre for Astrophysical Surveys. He was President of the Royal Astronomical Society 2010-12, is a Fellow of University College London, and holds an Honorary Degree from Claude Bernard University in Lyon, France. He is currently President of the European Astronomical Society.

He has a long standing commitment to engaging the public in science and has lectured widely on modern astronomy including on the Cunard Queen Mary 2 liner. He has also led trips to see the Northern Lights and the 2017 total eclipse. His research interests centre on cosmology and how galaxies form and evolve. He has observed at many of the world’s leading observatories including those in the Canary Islands, Hawaii, Chile, Australia and the United States. He has also been involved in the development of new astronomical instruments & telescopes. In recent years he has pioneered the use of a new class of astronomical spectrograph to measure the masses and ages of galaxies, as well as search for black holes in their nuclei.

11/2018: AGM & Talk: Quest for Beef Replacement (M. Springmann)

Place and Time: Abingdon, Thursday 15 November 2018 from 19:00 for 19:30

King Charles Room, King’s Head and Bell, (10 E St Helen St, Abingdon OX14 5EA)

TITLE: The Quest for the Best Beef Replacement

Livestock is a major driver of climate change, and red meat (including beef, lamb and pork) has recently been declared as likely carcinogenic by the cancer agency of the World Health Organisation. Against this backdrop, I evaluate a range of potential meat alternatives from nutritional, health, climate change, and affordability perspectives. The alternatives include traditional replacements based on legumes, nuts, tofu and wheat-based products, and also more recent products based on algae, jackfruit, fungus-based mycoprotein, and edible insects.

Speaker: Marco Springmann

Marco is a senior researcher in the Centre on Population Approaches for Non-Communicable Disease Prevention in the Nuffield Department of Population Health, and leads the Centre’s programme on environmental sustainability and public health. He is interested in the health, environmental, and economic dimensions of the global food systems. He often uses systems models to provide quantitative estimates on food-related questions. He is currently working on a multidisciplinary project focused on the analysis and management of animal products and their substitutes called “Livestock, Environment and People” (LEAP).
