Professor Daniel Nadeau’s research at the Université de Montréal is in infrared astronomy, a branch of science that peeks into the universe through wavelengths longer than what the human eye can perceive. Studying objects in the infrared is perfect for observing that which eludes our eyes in visible light. Using infrared observations, Professor Nadeau’s research focuses on three main areas:
Professor Nadeau’s research doesn’t stop at our cosmic doorstep. It extends to galaxies far, far away. In fact, the majority of radiation from distant galaxies reaches us in the form of infrared light.
Professor Nadeau and his team have spent three decades crafting powerful tools. They’ve constructed cameras and spectrometers for observatories like Mont Mégantic and the Canada-France-Hawaii Telescope. With these instruments, they’ve explored captivating phenomena, from supersonic star-forming jets ignited by hydrogen (H2) to the mind-bending effects of gravitational microlensing on the images of distant quasars.
A Focus on Brown Dwarfs
In recent years, their research has zeroed in on brown dwarfs. These celestial oddities weigh more than planets but less than stars. They can burn a special type of nuclear fuel called deuterium but eventually cool down, never reaching the stable fusion that powers stars.
Professor Daniel Nadeau’s work in the infrared allows us to see the universe through a different lens, revealing mysteries of the night sky that lie beyond the reach of our eyes. It’s a journey that expands our understanding of the cosmos, one infrared wavelength at a time.
