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. We will discuss important common challenges: calibration, sources of local correlated signals, foreground mitigation, cross-correlations, systematics from digital signal processing, validation, and software tools.

Wednesday Morning - Calibration I ; Session Chair - John Marriner

Instrumental systematics pose a significant threat to 21 cm telescopes aiming to detect a weak cosmological signal behind bright foreground emission. I will discuss the kinds of instrumental coupling systematics seen in HERA data and the tools we are developing to mitigate these systematics in 21 cm power spectrum analyses, including extended calibration techniques and complex visibility Fourier filters.
