Kashiwa Japan - A team of researchers led by Robert Quimby at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) has announced the discovery of a galaxy that magnified a background, Type Ia supernova thirtyfold through gravitational lensing. This is the first example of strong gravitational lensing of a supernova confirms the team's previous explanation for the unusual properties of this supernova.
The team has further shown how such discoveries of supernovae of Type Ia (SNIa) can be made far more common than previously thought possible. SNIa seen through gravitational lenses can be used to make a direct measurement of the universe's expansion rate (the Hubble parameter), so this discovery may have a significant impact on how cosmic expansion is studied in the future.
