Barry Madore
Widely known for his work on Cepheid variables, peculiar galaxies, and the extragalactic distance scale, Barry Madore divides his time between directing science for NED, the NASA/IPAC Extragalactic Database, and research at the Observatories, where he is resolving discrepancies between observations of galaxies at different wavelengths, with what is really happening during galactic evolution. Distant galaxies appear to be more ragged and disorganized than closer ones. These appearances could be legitimate features, or effects from the expansion of the universe, which progressively shifts ultraviolet photons from distant galaxies into the range sensed by the optical detectors. Madore is tackling this problem through observations and computer modeling.
During his visit to the IAC Dr Madore worked with IAC staff and students on the morphology and structure of galaxies, and on the detailed exploration of the most nearby galaxies which are neighbours of our Milky Way. He also discussed with colleagues about progress on the cosmological distance ladder and on the philosophy of science.
