Deep learning of multi-element abundances from high-resolution spectroscopic data

henrysky/astroNN 13 Aug 2018

We determine parameters and abundances for 18 individual elements at the $\approx 0. 03$ dex level, even at low signal-to-noise ratio.

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.
