RSD measurements from BOSS galaxy power spectrum using the halo perturbation theory model
Byeonghee Yu, Uros Seljak, Yin Li +1
We present growth of structure constraints from the cosmological analysis of the power spectrum multipoles of SDSS-III BOSS DR12 galaxies. We use the galaxy power spectrum model of…
The Simons Observatory: Constraining inflationary gravitational waves with multi-tracer B-mode delensing
Toshiya Namikawa, Anton Baleato Lizancos, Naomi Robertson +32
We introduce and validate a delensing framework for the Simons Observatory (SO), which will be used to improve constraints on inflationary gravitational waves (IGWs) by reducing th…
The Physical Origin of Dark Energy Constraints from Rubin Observatory and CMB-S4 Lensing Tomography
Byeonghee Yu, Simone Ferraro, Z Robert Knight +2
We seek to clarify the origin of constraints on the dark energy equation of state parameter from CMB lensing tomography, that is the combination of galaxy clustering and the cross-…
Fundamental Plane of BOSS galaxies: Correlations with galaxy properties, density field and impact on RSD measurements
Sukhdeep Singh, Byeonghee Yu, Uroš Seljak
Fundamental plane of elliptical galaxies can be used to predict the intrinsic size of galaxies and has a number of plausible application to study cosmology and galaxy physics. We p…
Inflation and Dark Energy from spectroscopy at
Simone Ferraro, Michael J. Wilson, Muntazir Abidi +140
The expansion of the Universe is understood to have accelerated during two epochs: in its very first moments during a period of Inflation and much more recently, at , when D…
Disconnected Covariance of 2-point Functions in Large-Scale Structure
Yin Li, Sukhdeep Singh, Byeonghee Yu +2
Optimal analyses using the 2-point functions of large-scale structure probes require accurate covariance matrices. A covariance matrix of the 2-point function comprises the disconn…
Towards Neutrino Mass from Cosmology without Optical Depth Information
Byeonghee Yu, Robert Z Knight, Blake D. Sherwin +3
With low redshift probes reaching unprecedented precision, uncertainty of the CMB optical depth is expected to be the limiting factor for future cosmological neutrino mass constrai…
The Simons Observatory: Science goals and forecasts
The Simons Observatory Collaboration, Peter Ade, James Aguirre +247
The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scient…
Cluster mislocation in kinematic Sunyaev-Zel'dovich (kSZ) effect extraction
Victoria Calafut, Rachel Bean, Byeonghee Yu
We investigate the impact of a variety of analysis assumptions that influence cluster identification and location on the kSZ pairwise momentum signal and covariance estimation. Pho…
Multitracer CMB delensing maps from Planck and WISE data
Byeonghee Yu, J. Colin Hill, Blake D. Sherwin
Delensing, the removal of the limiting lensing B-mode background, is crucial for the success of future cosmic microwave background (CMB) surveys in constraining inflationary gravit…
