From 7 minutes to 70000 years: the Renaissance of compact objects in binary (and triple) systems
Kevin Burdge (MIT)
Modern synoptic time domain surveys are revolutionizing our understanding of compact objects in binary systems, and transforming the field of gravitational wave multi-messenger astrophysics. In this talk, I will highlight some recent advances in our understanding of white dwarfs, neutron stars, and black holes in binary (and triple) systems. These results encompass phenomena which span orbital periods of 7 minutes to >70000 years, and have major implications in our understanding of compact object physics, as well as binary stellar evolution. I will conclude with a discussion of upcoming facilities including the Vera Rubin Observatory and LISA, and technological advances such as CMOS based imagers that will propel this field into its golden era.

On the Origin of Time
David Hertog (KU Leuven)
Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary career was how the universe could have created conditions so perfectly hospitable to life. Pondering this mystery led him to study the big bang origin, but his early work ran into a crisis when the math predicted many big bangs producing many universes, most far too bizarre to harbor life. Holed up in theoretical physics departments across the globe, Hawking and I worked shoulder to shoulder for twenty years, to develop a novel quantum framework for early universe cosmology that could account for the emergence of life. At the heart of our cosmogony lies a physical theory hat predicts that time and indeed physics itself fade away back into the big bang. In this colloquium I recount our quest to get a grips on the origin of time, and the bold new take on some of the universe’s fundamentals we are being led to.
