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 distribution. While the Betti numbers do not fully quantify topology, they extend the information beyond conventional cosmological studies of topology in terms of genus and Euler(More)
In order to unravel the high-energy physics of the early universe, several methods have been proposed to study the Cosmic Microwave Background (CMB). Current methods have posed bounds on the strength of non-Gaussianities in the CMB, but have so far not succeeded in constraining inflationary physics [8, 37, 23, 2, 38, 6, 21, 24]. This is one of the major(More)
