Unveiling dark energy properties with high-sensitivity cross-correlations of neutral hydrogen intensity mapping and galaxy surveys

Alessandro Marins, Chang Feng, Filipe B. Abdalla

The redshifted 21 cm line from the hyperfine structure of neutral hydrogen atoms is a promising tracer for the three-dimensional evolution of our universe. Its broad spatial and te…

The BINGO project X. Cosmological parameter constraints from HI Intensity Mapping lognormal simulations

Pablo Motta, Filipe B. Abdalla, Camila P. Novaes +12

Context. Building on the transformative success of optical redshift surveys, the emerging technique of neutral hydrogen (HI) intensity mapping (IM) offers a novel probe of large-sc…

The BINGO/ABDUS Project: Forecast for cosmological parameters from a mock Fast Radio Bursts survey

Xue Zhang, Yu Sang, Gabriel A. Hoerning +15

There are various surveys that will provide excellent data to search for and localize Fast Radio Bursts (FRBs). The BINGO project will be one such survey, and this collaboration ha…

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…

Cosmological Remapping for Efficient Generation of 21 cm Intensity Mapping Mocks

Rahima Mokeddem, Bruno B. Bizarria, Jiajun Zhang +10

We present a novel application of cosmological rescaling, or "remapping," to generate 21 cm intensity mapping mocks for different cosmologies. The remapping method allows for compu…
