Radio frequency interference mitigation using deep convolutional neural networks

28 Sep 2016

We employ a special type of Convolutional Neural Network, the U-Net, that enables the classification of clean signal and RFI signatures in 2D time-ordered data acquired from a radio telescope.

The impact of spectroscopic incompleteness in direct calibration of redshift distributions for weak lensing surveys

23 Mar 2020

We do so by simulating the process of assembling a spectroscopic sample (including observer-assigned confidence flags) and highlight the impacts of spectroscopic target selection and redshift failures.

Orbital dynamics of two circumbinary planets around misaligned eccentric binaries

29 Nov 2021

For planets that are highly misaligned with respect to an eccentric orbit binary, there are stationary (non-oscillating) tilt configurations that are generalisations of polar configurations for the single planet case.
