The stereoscopic imaging atmospheric Cherenkov technique, developed in the 1980s and 1990s, is now used by a number of existing and planned gamma-ray observatories around the world. It provides the...
View ArticleOn the universality of interstellar filaments: theory meets simulations and...
Filaments are ubiquitous in the universe. They are seen in cosmological structures, in the Milky Way centre and in dense interstellar gas. Recent observations have revealed that stars and star clusters...
View ArticleTensor calculus in polar coordinates using Jacobi polynomials [Replacement]
Spectral methods are an efficient way to solve partial differential equations on domains possessing certain symmetries. The utility of a method depends strongly on the choice of spectral basis. In this...
