Speakers Symposium 2024
Black Hole Symphonies
Dr. Beatrice Bonga
Abstract
When two black holes orbit each other and ultimately merge into a single black hole, the final black hole is initially deformed but becomes more and more like a standard black hole. During this last process, the black hole emits gravitational waves with a specific set of complex frequencies known as quasinormal modes (QNMs). These quasinormal modes are somewhat similar to the musical tones emitted by a violin (or any other musical instrument). The beauty is that these QNMs are remarkably simple and can be observed with gravitational wave detectors. I will discuss the exiting research that is currently been done and what the future holds for us!
Neutrino astronomy, a new window to our universe
Dr. Krijn de Vries
Abstract
In 2013, the IceCube neutrino observatory opened a new window on our universe with the discovery a cosmic neutrino flux. Recently, the first sources of these extremely energetic elementary particles were found. In this symposium, we present the IceCube neutrino observatory and discuss its latest results and implications.
Molecular Cocktails on the Rocks: ices in stellar nurseries
Dr. Thanja Lamberts
Abstract
I am an assistant professor at the Leiden Institute of Chemistry and at the Leiden Observatory. My group focuses on computational astrochemistry to unravel which molecules can be formed efficiently in the dense regions of the interstellar medium. I am particularly interested in the chemistry that takes place on the surface of ice-coated dust grains.
I will talk about the molecules that form on the very cold ices that cover small dust grains floating around in the densest regions of the interstellar medium. In other words, about the physical chemistry (or chemical physics) that produces both simple species, like methane, water or carbon dioxide, and complex molecules that approach sugars and aminoacids. Finally, I will explain how experimental and computational results are complementary to each other and important ingredients for astrochemistry.
