... A cyclic convolution of an input image weighted by gives output according to the following prescription: . ... The Fast Fourier Transform (FFT) algorithm used by the task works most efficiently if each dimension of the image is a multiple of 2, 3, 5 or 7. ... If the image is large and the number of convolvers small, this will generally be the FFT method; however direct convolution becomes more efficient if the image is divided into many small patches of different convolution. ...

The H II complex N 44 in the Large Magellanic Cloud (LMC) provides an excellent site to perform a detailed study of star formation in a mild starburst, as it hosts three regions of star formation at different evolutionary stages, and it is not as complicated and confusing as the 30 Doradus giant H II region. We have obtained Spitzer Space Telescope observations and complementary ground-based 4 m uBVIJK observations of N 44 to identify candidate massive young stellar objects (YSOs). ...

In this talk I give an introduction to generalizations of the Riemann zeta function called "Weyl group multiple Dirichlet series". Weyl group multiple Dirichlet series are sums in several variables whose coefficients involve Gauss sums and also reflect the combinatorics of a given root system. ... These functions and their residues unify and generalize a number of examples which have been previously treated individually, often with applications to number theory. ...
