Channel: Hubble Space Telescope

Category: Science & Technology

Description: Marc Sarzi, Armagh Observatory & Planetarium Integral-field spectroscopy (IFS) has driven tremendous progress in many areas of astronomy in the past two decades. Using a combination of imaging and spectroscopy, IFS observations can simultaneously map of a variety of physical properties across extended objects such as stellar clusters, gas nebulae or galaxies. Until recently, however, IFS has been the sole province of ground-based telescopes, which cannot rival the spatial resolution of the Hubble Space Telescope (HST) even when assisted by adaptive optics techniques. This situation has led to several instances where IFS data have been combined with HST observations to drive progress - ranging from the study of supermassive black holes to that of distant and early galaxies. Join Dr. Sarzi for an overview of IFS and some of it most fruitful ground/space collaborative studies. - News from the Universe starts at 3:23 - Main Talk starts at 12:16 Host: Frank Summers, Space Telescope Science Institute Recorded live on Tuesday, March 1, 2022 More information: stsci.edu/public-lectures
