What does the Marked Power Spectrum Measure? Insights from Perturbation Theory
Oliver H. E. Philcox, Elena Massara, David N. Spergel
The marked power spectrum is capable of placing far tighter constraints on cosmological parameters (particularly the neutrino mass) than the conventional power spectrum. What new i…
Beyond two-point statistics: using the minimum spanning tree as a tool for cosmology
Krishna Naidoo, Lorne Whiteway, Elena Massara +5
Cosmological studies of large-scale structure have relied on two-point statistics, not fully exploiting the rich structure of the cosmic web. In this paper we show how to capture s…
WFIRST: The Essential Cosmology Space Observatory for the Coming Decade
O. Doré, C. Hirata, Y. Wang +46
Two decades after its discovery, cosmic acceleration remains the most profound mystery in cosmology and arguably in all of physics. Either the Universe is dominated by a form of da…
Cosmic voids: a novel probe to shed light on our Universe
Alice Pisani, Elena Massara, David N. Spergel +26
Cosmic voids, the less dense patches of the Universe, are promising laboratories to extract cosmological information. Thanks to their unique low density character, voids are extrem…
The Wide Field Infrared Survey Telescope: 100 Hubbles for the 2020s
Rachel Akeson, Lee Armus, Etienne Bachelet +103
The Wide Field Infrared Survey Telescope (WFIRST) is a 2.4m space telescope with a 0.281 deg^2 field of view for near-IR imaging and slitless spectroscopy and a coronagraph designe…
Density and velocity profiles around cosmic voids
Elena Massara, Ravi K. Sheth
We study the evolution of the cross-correlation between voids and the mass density field - i.e. of void profiles. We show that approaches based on the spherical model alone miss an…
