First Results from HERA Phase II
The HERA Collaboration, Zuhra Abdurashidova, Tyrone Adams +83
We report the first upper limits on the power spectrum of 21-cm fluctuations during the Epoch of Reionization and Cosmic Dawn from Phase II of the Hydrogen Epoch of Reionization Ar…
Accessing the homogeneity scale with 21 cm intensity mapping surveys
Bruno B. Bizarria, Camila P. Novaes, Felipe Avila +4
The homogeneity scale, , offers a fundamental test of the Cosmological Principle, yet it has not yet been measured with 21cm intensity mapping surveys. A key limitation…
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…
The oscillatory anisotropy in the spatially flat cosmological models
Leandro G Gomes, Bruno B. Bizarria, Gabriel A. de Souza Silva +1
In this manuscript, we investigate the oscillatory behaviour of the anisotropy in the diagonal Bianchi-I spacetimes. Our starting point is a simplification of Einstein's equations…
