Detectability of the 21 cm signal with BINGO through cross-correlation with photometric surveys
Gabriel A. S. Silva, Camila P. Novaes, Carlos A. Wuensche +11
21 cm intensity mapping (HI IM) can efficiently map large cosmic volumes with good redshift resolution, but systematics and foreground contamination pose major challenges for extra…
