Lecture - Dr George Seabroke - The Gaia Revolution Continues

Gaia is a European Space Agency satellite that has been mapping individual stars in our Milky Way Galaxy since its launch in 2013.  I will explain how its 3 trillion measurements of 2 billion stars is causing a revolution in astronomy.  Science highlights will include the most recently discovered black hole (Gaia BH3) and how it relates to a personal historical coincidence.

About George

George obtained his Astrophysics PhD, "Probing the Milky Way galaxy through thick and thin (discs and halo) with the Correlation Radial Velocities (CORAVEL) and Radial Velocity Experiment (RAVE) surveys" from Cambridge in 2007, supervised by Gerry Gilmore and Wyn Evans. Ever since then he has been a post-doc funded by the UK Gaia grant. After his PhD, he joined the e2v centre for electronic imaging (CEI) at Brunel University. The CEI (and George) moved to the Open University in 2008. During this position, George modelled Gaia's e2v CCD pixel architecture, including the Supplementary Buried Channel, as part of the DPAC Working Group (WG) Radiation Task Force, CU5 DU10 and CU6.

In 2010, George moved to the Mullard Space Science Laboratory (MSSL), part of University College London, to become a Gaia Radial Velocity Spectrometer (RVS) Data Flow Scientist within CU6. As scientific lead of the MSSL Gaia team, George is involved in all aspects of MSSL's software contribution to CU6: Pre-processing, Calibration, Extraction and Multiple Transit Analysis. Through his RVS calibration role, George represents CU6 in the following DPAC WGs: Radiation Task Force, Offset Instability Task Force, Ground Based Observations for Gaia (GBOG) and Gaia Archive Preparation (GAP). He is also co-leading the Spectro Science Alerts and from January 2015 is a CU6 Deputy Manager.

The photo above is George's silhouette watching the Gaia launch live in French Guiana (the image is from a movie courtesy of Leanne Guy). George was unsuccessful in the 2008 ESA Astronaut Selection but was successful in 2009 in buying the inset photo from the Kennedy Space Center! As a Payload Expert, George helped to commission RVS after launch.

Since Gaia's launch, George has been very active in public outreach in the UK. This includes participation in the Gaia Live in Schools event, a Gaia teacher training event and the Royal Society Summer Science Exhibition.
