Foreground Simulation Suite Plus for the 21 cm Reionization Signal Detection

The Fg21Sim+ is a simulation suite in the radio domain aiming to offer a high-resolution, high-fidelity modelling of the various foregrounds for the 21 cm signal detection.

This is the next-gen version of our fg21sim low-frequency radio simulator. We build the Fg21Sim+ to generate a full sky simulation map for radio facilities like BINGO, MWA, and SKA.

Initial Release

The Fg21Sim+ package is under its initial realise with the following individual models:

  • ESim for extragalactic discrete emission
  • GSim for Galactic diffuse emission
  • 21cmSim for the 21-cm signals

The model-defect simulation is an ongoing project @ Fg21Sim team, we are happy to release the 1st defect model:

  • BlendSim for simulating blending of discrete sources

Dev Status

The integration of individual models into a full suite is a 2nd phase development goal. If prefer the traditional usage with a config file. You can still use the last-gen fg21sim.
