The YMW16 Electron Density Model for Estimating Pulsar and FRB Distances
• Developed by Jumei Yao, RNM and Nina Wang – paper to be submitted today
• Electron density models for the Galaxy, Magellanic Clouds and intergalactic medium
• Galactic model based on independent distances for 189 pulsars – 31 fitted parameters, 57 fixed parameters • Magellanic Cloud model based on spectral-line and radio
continuum data – 3 fitted parameters, 16 fixed parameters
• IGM model based on Katz (2016) relations, 1 fixed parameter
Components of Galactic Model • Thick disk, DMperp=19 cm-3 pc,
