A high-significance detection of primordial tidal torque imprints
Ming-Jie Sheng, Hao-Ran Yu, Min Bao +8
Tidal-torque theory predicts that galaxy angular momenta are imprinted by the primordial tidal field acting on proto-structures and that they can retain information about the early…
Detection of the Cosmological 21 cm Signal in Auto-correlation at z ~ 1 with the Canadian Hydrogen Intensity Mapping Experiment
CHIME Collaboration, Mandana Amiri, Kevin Bandura +36
We present the first detection of the cosmological 21 cm intensity mapping signal in auto-correlation at z ~ 1 with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). Usin…
Measurement of the Dispersion$\unicode{x2013}$Galaxy Cross-Power Spectrum with the Second CHIME/FRB Catalog
Haochen Wang, Kiyoshi Masui, Shion Andrew +18
The dispersion of extragalactic fast radio bursts (FRBs) can serve as a powerful probe of the diffuse plasma between and surrounding galaxies, which contains most of the Universe's…
Systematic analysis of Parity-Violating modes
Hong-Ming Zhu, Ue-Li Pen
Recent reports of cosmological parity violation in the 4PCF raises the question of how such violations could be systematically generated. Here we present a constructive procedure t…
Correlation-based Beam Calibration of 21cm Intensity Mapping
Jiacheng Ding, Xin Wang, Ue-Li Pen +1
Foreground removal presents a significant obstacle in both current and forthcoming intensity mapping surveys. While numerous techniques have been developed that show promise in sim…
Measuring cosmic expansion with diffractive gravitational scintillation of nanoHertz gravitational waves
Dylan L. Jow, Ue-Li Pen
The recent discovery of ultra-long wavelength gravitational waves through the advent of pulsar timing arrays (PTA) has opened up new avenues for fundamental science. Here we show t…
