To advance progress in the practice of 21 cm intensity mapping we are organizing a community workshop on 21 cm cosmology instrumentation in Madison Wisconsin. The workshop focuses on sharing recent progress and challenges from all the major 21 cm intensity mapping efforts, both EoR and post-EoR, to help this field reach its full potential.
Workshop topics:
Beam and gain calibration
- the practice of calibration from the sky, redundant baselines and their combination
- use of drones, holography and EM simulation
- pass band structures
Sources of correlated signals (other than sky)
- cross talk, feed cross coupling, ground pickup
Advances in mitigation of foregrounds
- foreground wedge and its leakage in practice
- identifying the 21 cm signal in the presence of foregrounds
- cross-correlations as a tool:
- for identifying systematics
- for validation
Systematics associated with digital signal processing
Validation- building confidence in the reality of an extracted 21 cm signal; use of independent simulations and analysis pipelines; blind analysis
