Mapping stellar surfaces III: An Efficient, Scalable, and Open-Source Doppler Imaging Model

rodluger/showyourwork 12 Oct 2021

It is also critical to the detection and characterization of extrasolar planets, in particular those targeted in extreme precision radial velocity (EPRV) searches, which must contend with stellar variability that is often orders of magnitude stronger than the planetary signal.

Radio frequency interference mitigation using deep convolutional neural networks

jakeret/unet 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

JustGlowing/minisom 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

hannorein/rebound 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.
