The assembly history of NGC 1365 through chemical archaeology

Lisa J. Kewley, Kathryn Grasha, Alex Garcia +8

Galaxies build through infalling gas and galaxy mergers. Tracking the dynamical history of a galaxy from a single snapshot in time is notoriously difficult. We show that the dynami…

On Smooth Combinatorial Products of Simplices

Juliana Curtis, Tuong Le, Chayim Lowen

We show that every lattice weak Minkowski summand of a smooth polytope combinatorially isomorphic to a product of simplices has a quadratic triangulation. This is achieved by ident…

Morphology of frozen labyrinths from irreversible threshold dynamics

Daniel Richard Levy

Majority threshold dynamics, in which each agent adopts the dominant state in a weighted neighborhood, relaxes a binary field toward consensus or stripes. We study what happens whe…
