Walter Jaffe is Associate Professor at Leiden University and Professor Instrumental Astronomy at the University of Amsterdam.
Walter Jaffe's interests are AGN accretion disks, molecular gas in cooling flows, nuclear structures in early galaxies and infrared interferometry.
In 1983, Jaffe proposed the Jaffe Profile. The Jaffe Profile is a mathematical function that is used to describe the distribution of mass or light in ellipitcal galaxies and the bulges of spiral galaxies. Its usefulness derives from the fact that it accurately reproduces a de Vaucouleurs profile when projected onto the sky.
