SUMMARY:General Meeting - April 2026
DESCRIPTION: Join Zoom\n\nFree and open to the public but per our host’s policy\, minors (under 18) are welcome to attend as long as they are accompanied by their parent or guardian at all times.\nThis meeting’s speaker will present online.\n  \nSupernovae\, Dark Energy\, and the\n  \nMystery of the Accelerating Universe\n  \n  \n \nType Ia supernovae are brilliant explosions of white dwarf stars and are some of the most powerful tools for measuring the universe. By comparing how bright these supernovae appear to how bright they really are\, astronomers can measure distances across billions of light-years. In the late 1990s\, these measurements led to one of the most surprising discoveries in the history of science: the expansion of the universe is speeding up\, driven by a mysterious phenomenon that was named dark energy. \nIn this talk\, we will explore how supernova discoveries (including contributions from dedicated amateur astronomers) feed into modern cosmological measurements. Along the way\, we’ll see how today’s observations are deepening the mystery of dark energy rather than closing the case. The accelerating universe remains one of the biggest puzzles in physics and supernovae are still lighting the way toward the answer. \n\nDavid Rubin is an Associate Professor of Physics and Astronomy at the University of Hawai‘i at Mānoa. His research focuses on using exploding stars called Type Ia supernovae to measure the expansion history of the universe and understand the nature of dark energy. He works on survey design\, calibration\, and statistical methods for current and next-generation observatories\, including the Nancy Grace Roman Space Telescope. \nDr. Rubin received his Ph.D. in physics from the University of California\, Berkeley working with Saul Perlmutter. He is still a member of the Supernova Cosmology Project and has authored or co-authored numerous publications on supernova cosmology and the accelerating universe. \nViews: 0

SUMMARY:General Meeting - May 2026
DESCRIPTION: Join Zoom\n\nFree and open to the public but per our host’s policy\, minors (under 18) are welcome to attend as long as they are accompanied by their parent or guardian at all times.\nThis meeting’s speaker will present online.\n  \nEarly galaxies and infant black holes\n  \nin the primeval Universe\n  \n   \nFinding and understanding the nature of the first stars at cosmic dawn is one of the most important and most ambitious goals for modern astrophysics. The first populations of stars produced the first chemical elements heavier than helium and formed the first\, small protogalaxies\, which then evolved\, across the cosmic epoch\, into the large and mature galaxies\, such as the Milky Way and those in our local neighbour. Equally important and equally challenging is the search\, in the early Universe\, of the seeds of the first population of black holes\, which later evolved in the supermassive black holes at the centre of galaxies\, with masses even exceeding a billion times the mass of the Sun. When matter accretes on such supermassive black holes it can become so luminous to vastly outshine the light emitted by all stars in their host galaxy. \n  \nSince its launch\, about two years ago\, the James Webb Space Telescope has been revolutionizing this area of research. Its sensitivity in detecting infrared light from the remotest parts of the Universe is orders of magnitude higher than any previous observatory\, an historical leap in astronomy and\, more broadly\, in science. I will presents some of the extraordinary discoveries from the Webb telescope\, which have resulted in several unexpected findings. I will also discuss the new puzzles and areas of investigation that have been opened by Webb’s observations\, how these challenge theoretical models\, and the prospects of further progress in the coming years. \n \nRoberto Maiolino is Professor of Experimental Astrophysics in the Department of Physics and at the Kavli Institute for Cosmology\, University of Cambridge. He is also an Honorary Professor at University College London and a Royal Society Research Professor. \nHe has served as Director of the Kavli Institute for Cosmology\, Cambridge\, and is a Fellow of the Royal Society. He was knighted by the President of Italy in the Order of the Star of Italy and was awarded the Blaauw Honorary Professorship at the University of Groningen. \nHis research focuses on the formation of galaxies and black holes\, using observations from some of the largest ground-based and space telescopes. He has played a leading role in several major projects\, including the James Webb Space Telescope\, the MOONS spectrograph for the Very Large Telescope\, and the ANDES spectrograph for the Extremely Large Telescope. \n  \n  \nViews: 0
