LunCH Lecture – Dr. Rybak

The sub-millimetre Universe

Looking at the night sky, our eyes – and the most powerful telescopes – observe only a fraction of all the light in the Universe. This is because our own Milky Way and distant galaxies contain vast amounts of dust that absorb visible light. To study this “obscured” Universe, we need to move to far-infrared and sub-millimetre wavelengths. Yet the technology at these wavelengths is still maturing: taking beautiful, high-resolution images and rich spectra is challenging.

Over the last decade, massive leaps in resolution and sensitivity at sub-mm wavelengths have dramatically changed our view of the dust-obscured Universe. I will showcase the wonders of the obscured Universe, from the cradles of stars in our neighbourhood to supermassive black holes, and most distant galaxies. I will also outline the next frontier: making a three-dimensional map of the obscured structures in the Universe and how the current research at TU Delft brings us closer to realising this aim.
