The Radio and Microwave Sky as Seen by Juno on its Mission to Jupiter
Christopher Anderson, Philippe Berger, Tzu-Ching Chang +4
We present six nearly full-sky maps made from data taken by radiometers on the Juno satellite during its 5-year flight to Jupiter. The maps represent integrated emission over $\sim…
A GPU Spatial Processing System for CHIME
Nolan Denman, Andre Renard, Keith Vanderlinde +4
We present an overview of the Graphics Processing Unit (GPU) based spatial processing system created for the Canadian Hydrogen Intensity Mapping Experiment (CHIME). The design empl…
Nonlinear 3D Cosmic Web Simulation with Heavy-Tailed Generative Adversarial Networks
Richard M. Feder, Philippe Berger, George Stein
Fast and accurate simulations of the non-linear evolution of the cosmic density field are a major component of many cosmological analyses, but the computational time and storage re…
Canceling out intensity mapping foregrounds
Patrick C. Breysse, Christopher J. Anderson, Philippe Berger
21 cm intensity mapping has arisen as a powerful probe of the high-redshift universe, but its potential is limited by extremely bright foregrounds and high source confusion. In thi…
Tomography of the Cosmic Dawn and Reionization Eras with Multiple Tracers
Tzu-Ching Chang, Angus Beane, Olivier Dore +41
The Cosmic Dawn and Reionization epochs remain a fundamental but challenging frontier of astrophysics and cosmology. We advocate a large-scale, multi-tracer approach to develop a c…
Spectral Kurtosis Based RFI Mitigation for CHIME
Jacob Taylor, Nolan Denman, Kevin Bandura +5
We present the implementation of a spectral kurtosis based Radio Frequency Interference detection system on the CHIME instrument and its reduced-scale pathfinder. Our implementatio…
A volumetric deep Convolutional Neural Network for simulation of mock dark matter halo catalogues
Philippe Berger, George Stein
For modern large-scale structure survey techniques it has become standard practice to test data analysis pipelines on large suites of mock simulations, a task which is currently pr…
The CHIME Fast Radio Burst Project: System Overview
FRB Collaboration, M. Amiri, K. Bandura +49
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a novel transit radio telescope operating across the 400-800-MHz band. CHIME is comprised of four 20-m x 100-m semi-cy…
Limits on the ultra-bright Fast Radio Burst population from the CHIME Pathfinder
CHIME Scientific Collaboration, Mandana Amiri, Kevin Bandura +35
We present results from a new incoherent-beam Fast Radio Burst (FRB) search on the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Pathfinder. Its large instantaneous field…
An efficient method for removing point sources from full-sky radio interferometric maps
Philippe Berger, Niels Oppermann, Ue-Li Pen +1
A new generation of wide-field radio interferometers designed for 21-cm surveys is being built as drift scan instruments allowing them to observe large fractions of the sky. With l…
Holographic Beam Mapping of the CHIME Pathfinder Array
Philippe Berger, Laura B. Newburgh, Mandana Amiri +32
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) Pathfinder radio telescope is currently surveying the northern hemisphere between 400 and 800 MHz. By mapping the large s…
Testing the Origin of Cosmological Magnetic Fields through the Large-Scale Structure Consistency Relations
P. Berger, A. Kehagias, A. Riotto
We study the symmetries of the post-recombination cosmological magnetohydrodynamical equations which describe the evolution of dark matter, baryons and magnetic fields in a self-co…
