The FRB--Galaxy Overdensity Cross-Correlation Statistic in Dispersion Space
Ryan Raikman, Haochen Wang, Kiyoshi Masui +1
The paper introduces a new angular cross‑power spectrum statistic that correlates FRB dispersion measures with galaxy density, showing it is more informative than previous methods…
Fast radio burst dispersion is an unbiased tracer of matter on large scales
Shion Andrew, Haochen Wang, Kiyoshi Masui +6
The dispersion of fast radio bursts (FRBs) measures the column density of free electrons, tracing the diffuse ionized gas that contains more than of all baryons. On linear s…
Constraining Gas Mass Fractions in Galaxy Groups and Clusters with the First CHIME/FRB Outrigger
Adam E. Lanman, Sunil Simha, Kiyoshi W. Masui +16
In recent years, localized fast radio bursts (FRBs) have emerged as a powerful tool to study the structure of the baryonic matter in the universe. Their dispersion measures (DMs) s…
A spatial filter for mitigating radio interference and its application to CHIME/FRB Outriggers
Shion Andrew, Juan Mena-Parra, Haochen Wang +16
The sensitivity of radio telescopes is becoming increasingly limited by the presence of radio frequency interference (RFI), which will worsen as the radio spectrum becomes more cro…
Interpretation of 21 cm Auto Power Spectrum Measurement at by the Canadian Hydrogen Intensity Mapping Experiment
CHIME Collaboration, Mandana Amiri, Kevin Bandura +21
Observations with the Canadian Hydrogen Intensity Mapping Experiment (CHIME) have been used to measure the 21 cm intensity mapping auto power spectrum, at , over a frequen…
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…
