BICEP / Keck XVI: Characterizing Dust Polarization through Correlations with Neutral Hydrogen

Kavli Affiliate: C. L. Kuo | First 5 Authors: BICEP/Keck Collaboration, :, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: We characterize Galactic dust filaments by correlating BICEP/Keck and Planck data with polarization templates based on neutral hydrogen (H I) observations. Dust polarization is important for both our understanding of astrophysical processes in […]

Tracer-Field Cross-Correlations with $k$-Nearest Neighbor Distributions

Kavli Affiliate: Tom Abel | First 5 Authors: Arka Banerjee, Tom Abel, , , | Summary: In astronomy and cosmology, significant effort is devoted to characterizing and understanding spatial cross-correlations between points – e.g. galaxy positions, high energy neutrino arrival directions, X-ray and AGN sources, and continuous field – e.g. weak lensing and Cosmic Microwave […]

Search for anisotropic, birefringent spacetime-symmetry breaking in gravitational wave propagation from GWTC-3

Kavli Affiliate: Lijing Shao | First 5 Authors: Leïla Haegel, Kellie O’Neal-Ault, Quentin G. Bailey, Jay D. Tasson, Malachy Bloom | Summary: An effective field theory framework, the Standard-Model Extension, is used to investigate the existence of Lorentz and CPT-violating effects during gravitational wave propagation. We implement a modified equation for the dispersion of gravitational […]

Polarisation of magnetospheric curvature radiation in repeating fast radio bursts

Kavli Affiliate: Kejia Lee | First 5 Authors: Wei-Yang Wang, Jin-Chen Jiang, Kejia Lee, Renxin Xu, Bing Zhang | Summary: Fast radio busts (FRBs) can exhibit a wide variety of polarisation properties, not only between sources but also from burst to burst for a same one. In this work, we revisit the polarisation characters of […]

Unweighted estimation based on optimal sample under measurement constraints

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, HaiYing Wang, Shifeng Xiong, , | Summary: To tackle massive data, subsampling is a practical approach to select the more informative data points. However, when responses are expensive to measure, developing efficient subsampling schemes is challenging, and an optimal sampling approach under measurement constraints was […]
