Hubble from Space and Integral-field Spectroscopy from the Ground

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.

Great lecture! I was wondering about how to interpret the different spectra from a star and galaxies, and GC. The explanation of how the different techniques to acquire spectroscopy also was great. Thanks!
Im new to amateur astronomy its fun yet as exciting as it is i have so much to learn still the fundamentals and ins-and-outs
After hearing him say “all right” and “ok” 20 times in a minute or two, I bailed out. How does a person get such an annoying verbal tic and not be told about it? All right and OK.
