On Determining if Tree-based Networks Contain Fixed Trees
Maria Anaya, Olga Anipchenko-Ulaj, Aisha Ashfaq +9
We address an open question of Francis and Steel about phylogenetic networks and trees. They give a polynomial time algorithm to decide if a phylogenetic network, N, is tree-based…
CMB-S4: Forecasting Constraints on Primordial Gravitational Waves
S4 Collaboration, Kevork Abazajian, Graeme E. Addison +233
CMB-S4---the next-generation ground-based cosmic microwave background (CMB) experiment---is set to significantly advance the sensitivity of CMB measurements and enhance our underst…
CMB-S4 Science Case, Reference Design, and Project Plan
Kevork Abazajian, Graeme Addison, Peter Adshead +222
We present the science case, reference design, and project plan for the Stage-4 ground-based cosmic microwave background experiment CMB-S4.
Optical Characterization of the SPT-3G Focal Plane
Zhaodi Pan, Peter Ade, Zeeshan Ahmed +73
The third-generation South Pole Telescope camera is designed to measure the cosmic microwave background across three frequency bands (95, 150 and 220 GHz) with ~16,000 transition-e…
Snowmass 2021 CMB-S4 White Paper
Kevork Abazajian, Arwa Abdulghafour, Graeme E. Addison +353
This Snowmass 2021 White Paper describes the Cosmic Microwave Background Stage 4 project CMB-S4, which is designed to cross critical thresholds in our understanding of the origin a…
CMB-S4 Decadal Survey APC White Paper
Kevork Abazajian, Graeme Addison, Peter Adshead +222
We provide an overview of the science case, instrument configuration and project plan for the next-generation ground-based cosmic microwave background experiment CMB-S4, for consid…
Properties for the Frechet Mean in Billera-Holmes-Vogtmann Treespace
Maria Anaya, Olga Anipchenko-Ulaj, Aisha Ashfaq +9
The Billera-Holmes-Vogtmann (BHV) space of weighted trees can be embedded in Euclidean space, but the extrinsic Euclidean mean often lies outside of treespace. Sturm showed that th…
