Transient Blurring of the Scintillation Arc of Pulsar B1737+13
Yen-Hua Chen, Samuel Siegel, Daniel Baker +2
For many pulsars, the scattering structures responsible for scintillation are typically dominated by a single, thin screen along the line of sight, which persists for years or deca…
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…
Superfluid-tight cryogenic receiver with continuous sub-Kelvin cooling for EXCLAIM
Sumit Dahal, Peter A. R. Ade, Christopher J. Anderson +67
The EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM) is a balloon-borne telescope designed to survey star formation over cosmological time scales using intensity…
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…
Holographic Beam Measurements of the Canadian Hydrogen Intensity Mapping Experiment (CHIME)
Mandana Amiri, Arnab Chakraborty, Simon Foreman +17
We present the first results of the holographic beam mapping program for the Canadian Hydrogen Intensity Mapping Experiment (CHIME). We describe the implementation of the holograph…
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…
