Felix: A Topology based Framework for Visual Exploration of Cosmic Filaments
Nithin Shivshankar, Pratyush Pranav, Vijay Natarajan +3
The large-scale structure of the universe is comprised of virialized blob-like clusters, linear filaments, sheet-like walls and huge near empty three-dimensional voids. Characteriz…
Alpha, Betti and the Megaparsec Universe: on the Topology of the Cosmic Web
Rien van de Weygaert, Gert Vegter, Herbert Edelsbrunner +13
We study the topology of the Megaparsec Cosmic Web in terms of the scale-dependent Betti numbers, which formalize the topological information content of the cosmic mass distributio…
Probing Dark Energy with Alpha Shapes and Betti Numbers
Rien van de Weygaert, Pratyush Pranav, Bernard J. T. Jones +8
We introduce a new descriptor of the weblike pattern in the distribution of galaxies and matter: the scale dependent Betti numbers which formalize the topological information conte…
