February 25th            

Jenifer Millard, Astrophysics PhD student, Cardiff University  :         
A brief journey through historical studies of galaxies, building up to our current understanding of the major galaxy types that exist today, examining the differences between these and looking at them using different wavelengths of light. We’ll also see how dust is to astronomers how bones are to a palaeontologist… Finally, I’ll finish with a brief look at my current research work in this field.

March 11th    

Professor Jane Greaves, Astronomy Group, Cardiff School of Physics and Astronomy  :          
“Spinning Space Diamonds”.  Jane talked about the sparkling trail of diamonds from exploding stars to the birth of the solar system. Her team recently found diamonds orbiting a few very young luminous stars, and she discussed how this chance discovery came about and how it helped to solve a problem of mystery radio waves that has existed for over 20 years.

March 25th                                                                  :           AGM

April 8th         

Chris Allton, Professor of Theoretical Physics, Department of Physics, Swansea University :
All the matter we know about in the universe is comprised of just 19 particles.  Quarks are the most massive and they combine together to form neutrons and protons to make atomic nuclei. Quarks are bound together by the Strong Force – and this Force is incredibly strong, each quark is held to its neighbour by a force equivalent to the weight of three elephants!  At high temperatures and pressures, around a trillion degrees, quarks can become free.  The talk explores how this new phase of matter and neutron stars are related.

April 22nd                                                                   :           BANK HOLIDAY

May 13th        

Dr Andreas Papageorgiou, Research Associate, Astronomy Instrumentation Group, Cardiff School of Physics & Astronomy.
Since 2008, Dr Papageorgiou has been full-time involved with all phases of space telescope missions.  He will be talking about the work he was involved in with the Spectral and Photometric Imaging Receiver (SPIRE) which was on the Herschel infra red space telescope, which operated from 2009 to 2013.

June 10th        
“Round the Table” Discussion
         :           List of suggested topics

Water in the Solar system  –  Water on Earth, the moon and Pluto.
Mars  –  History, minerals, soil and potential for oxygen production.
Exo planets – more discoveries and a “Forbidden Planet”
Supernova  –  including human evolution, lots of new supernova and white dwarf fusion
TESS mission – Latest news from the NASA’s Transiting Exoplanet Survey Satellite launched in 2018

June 24th

Professor Matt Griffin, Astronomy Instrumentation Group, Cardiff Uni. will be coming to talk to us on the subject of “Characterising Extra-solar Planets”.  Brief summary:-

“Around 4,000 extra-solar planets have now been detected, and studying them is one of the most important areas of astronomical research today.
Using the technique of transit spectroscopy, it is now starting to be possible to study exoplanets and determine the chemical composition and physical constitutions in their atmosphere.
This will be an important objective for both NASA’s James Webb Space Telescope, due for launch in 2022, and ESA’s ARIEL satellite, a purpose-built exoplanet observatory, to be launched in 2028.
I’ll describe the technique and what we can learn from it, and how one day we may be able to detect the presence of life on Earth-like planets.”

July  –  August  :  Summer Break, NO MEETINGS

September 9th
“Around the Table” Discussion         :        Some notes on these suggested topics can be found on the downloads page HERE

1  :  Expansion of the Universe  :  100 years (or so) of theory and observation.
We have gone from an expanding universe, Hubble 1929, to an accelerating universe in 1998.
What new insights or conclusions have the last 20 years brought? Some questions that could be asked:-
What is the Standard Model, what is the Hubble constant that is being measured, what are the standard candles used for estimating distances, what is the discrepancy that threatens the standard model that the cosmologists are concerned about?  Where do we go next?
2  :  Dark Matter: 
          Did DM exist before the “Big Bang” and why is it suggested that the Milky Way disk is warped and twisted.
3  :  Missions:-
          The Parker Solar probe  :  New Horizons  :  James Webb Telescope  :  Square kilometre Array  :  Atomic clocks in space  :  Europa Clipper Mission.
4  :  Evolution of Stars & Galaxies
          One of the earliest stars, known as population III, found 35,000 light years away.
          Using a new technique 39 ancient galaxies have been identified.  The discovery doesn’t fit well with current models of the universe, much is hoped to be learnt from further research.
5  :  Black Holes
           A massive stellar Black Hole found that confounds current theories.

September 23rd

Dr Duncan MacLeod, Gravitational Physics Group, Cardiff University : talking on the subject of LIGO and Gravitational Waves.  He has suggested he could give a demonstration of how to download LIGO data and process it on our own computer.
Dr MacLeod is a Sêr Cymru COFUND Fellow in the Gravitational Physics group of the School of Physics and Astronomy. His research targets development of improved user-facing software utilities for accessing, processing, and visualising data from the second-generation of ground-based gravitational-wave detectors, primarily the Laser Interferometer Gravitational-wave Observatory (LIGO).

October 14th 
 Another talk in our Basic Series.  David Thomas FRAS from Usk AS will give a talk on “The search for the star of Bethlehem”.  This well researched talk will include descriptions of many of the phenomena that are potential candidates for what the Magi are reported to have seen and will highlight the many problems and issues that astronomers face when trying to interpret observations reported in ancient times.

October 28th 

“ Decoding black holes via holography” – Professor Prem Kumar

Black holes are amongst the most fascinating objects in the universe. Ranging from a few solar masses to a million solar masses, they hold the key to our understanding of the nature of spacetime and how quantum mechanics can be reconciled with
gravity. Prof. Kumar will review some remarkable theoretical developments that have revealed deep connections
between black hole physics and seemingly unrelated physical phenomena. The emergence of gravitational
wave astronomy in recent years means that some of these remarkable aspects of black holes may
be tested and revealed in the immediate future.

Prem Kumar is a Professor of Theoretical Physics with the Particle Physics and Cosmology Theory Group, Swansea University, and has been at Swansea since 2005. His specialization is in the areas of Quantum Field Theory and String Theory, and he is interested in exploring physics that lies at the interface of these two subjects, bridging strongly quantum  and gravitational phenomena.

After schooling in Calcutta, India and subsequently a Bachelor’s in Electrical Engineering at the Indian Institute of Technology Madras in ‘93, he pursued postgraduate studies in Theoretical Physics at  Carnegie Mellon University, Pittsburgh USA and obtained a PhD in 1998. Following this Prof. Kumar held postdoctoral research positions at the University of Washington, Seattle and at Cambridge University before joining Swansea University in 2005.

November 11th 
Dr Annabel Cartwright, Director of Undergraduate Studies, Physics Education Research Group, Cardiff University 
Venus theory.  Dr Cartwright’s research interests include the evolution of Earth as a habitable planet, and possibility of transfer of complex life from Venus.
