Plan for next Galactic Phase-2sims
Phase 2: Foreground modeling update
Will generate second set of PySM maps using: https://github.com/bthorne93/PySM_public
Phase-1 model = s1d1a1 Model planned to be used = s3d4a2
This has the following components: Synchrotron, model = synchrotron3 (same MAMD spatial variation as ‘nominal’, but globally curved power law) ThermalDust, model = dust4 (two components, using Finkbeiner/Meisner model) SpinningDust, model = spdust2 (2% polarized AME)
The details are all described further in Thorne et al, https://arxiv.org/abs/1608.02841. The effects on the global spectrum are shown in this figure:
Next step underway is implementing Brandon Hensley’s new dust model into PySM code; Brandon and Ben are working on this.
