Radio frequency interference mitigation using deep convolutional neural networks
Joel Akeret, Chihway Chang, Aurelien Lucchi +1
We propose a novel approach for mitigating radio frequency interference (RFI) signals in radio data using the latest advances in deep learning. We employ a special type of Convolut…
An Integrated System at the Bleien Observatory for Mapping the Galaxy
Chihway Chang, Christian Monstein, Joel Akeret +5
We describe the design and performance of the hardware system at the Bleien Observatory. The system is designed to deliver a map of the Galaxy for studying the foreground contamina…
HIDE & SEEK: End-to-End Packages to Simulate and Process Radio Survey Data
Joel Akeret, Sebastian Seehars, Chihway Chang +3
As several large single-dish radio surveys begin operation within the coming decade, a wealth of radio data will become available and provide a new window to the Universe. In order…
SPOKES: an End-to-End Simulation Facility for Spectroscopic Cosmological Surveys
B. Nord, A. Amara, A. Refregier +15
The nature of dark matter, dark energy and large-scale gravity pose some of the most pressing questions in cosmology today. These fundamental questions require highly precise measu…
A new method to measure galaxy bias by combining the density and weak lensing fields
Arnau Pujol, Chihway Chang, Enrique Gaztañaga +9
We present a new method to measure the redshift-dependent galaxy bias by combining information from the galaxy density field and the weak lensing field. This method is based on Ama…
