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

23 Mar 2020JustGlowing/minisom

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.

# A New Electron Density Model for Estimation of Pulsar and FRB Distances

29 Oct 2016telegraphic/pygedm

We present a new model for the distribution of free electrons in the Galaxy, the Magellanic Clouds and the intergalactic medium (IGM) that can be used to estimate distances to real or simulated pulsars and fast radio bursts (FRBs) based on their dispersion measure (DM).
