Differentiable Stochastic Halo Occupation Distribution
Benjamin Horowitz, ChangHoon Hahn, Francois Lanusse +2
In this work, we demonstrate how differentiable stochastic sampling techniques developed in the context of deep Reinforcement Learning can be used to perform efficient parameter in…
Foreground-immune CMB lensing reconstruction with polarization
Noah Sailer, Simone Ferraro, Emmanuel Schaan
Extragalactic foregrounds are known to generate significant biases in temperature-based CMB lensing reconstruction. Several techniques, which include ``source hardening'' and ``she…
Joint velocity and density reconstruction of the Universe with nonlinear differentiable forward modeling
Adrian E. Bayer, Chirag Modi, Simone Ferraro
Reconstructing the initial conditions of the Universe from late-time observations has the potential to optimally extract cosmological information. Due to the high dimensionality of…
Report of the Topical Group on Dark Energy and Cosmic Acceleration: Complementarity of Probes and New Facilities for Snowmass 2021
Brenna Flaugher, Vivian Miranda, David J. Schlegel +27
The mechanism(s) driving the early- and late-time accelerated expansion of the Universe represent one of the most compelling mysteries in fundamental physics today. The path to und…
The MegaMapper: A Stage-5 Spectroscopic Instrument Concept for the Study of Inflation and Dark Energy
David J. Schlegel, Juna A. Kollmeier, Greg Aldering +86
In this white paper, we present the MegaMapper concept. The MegaMapper is a proposed ground-based experiment to measure Inflation parameters and Dark Energy from galaxy redshifts a…
A Spectroscopic Road Map for Cosmic Frontier: DESI, DESI-II, Stage-5
David J. Schlegel, Simone Ferraro, Greg Aldering +62
In this white paper, we present an experimental road map for spectroscopic experiments beyond DESI. DESI will be a transformative cosmological survey in the 2020s, mapping 40 milli…
