      The picture on the cover page in 2012 shows a supernova of type Ia. The precise measurements of such massive star eruptions led the three astrophysicists Saul Perlmutter, Brian P. Schmitt and Adam Riess to the conclusion that the universe is nowadays expanding faster than expected. For this discovery the three physicists were honored by the Nobel Prize of the year 2011.

      Reflexive polygons have attracted great interest both in mathematics and in physics. This paper discusses a new aspect of the existing study in the context of quiver gauge theories. These theories are 4d supersymmetric worldvolume theories of D3 branes with toric Calabi-Yau moduli spaces that are conveniently described with brane tilings. We find all 30 theories corresponding to the 16 reflexive polygons, some of the theories being toric (Seiberg) dual to each other. It is shown that the lattice of generators is the dual reflexive polygon of the toric diagram.
