Foreground removal and 21 cm signal estimates: comparing different blind methods for the BINGO Telescope
Alessandro Marins, Filipe B. Abdalla, Elcio Abdalla +17
The BINGO radiotelescope will observe hydrogen distribution using Intensity Mapping (IM) to analyze the Dark Energy paradigm through Baryon Acoustic Oscillations. The target signal…
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…
Machine learning analysis of Photometric data from the Dark Energy Survey
Elcio Abdalla, Filipe B. Abdalla, Alessandro Marins +3
In order to retrieve cosmological parameters from photometric surveys, we need to estimate the distribution of the photometric redshift in the sky with excellent accuracy. We use a…
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…
Echoes of bimodal axial gravitational perturbations in a uniform-density star in Einstein-Ãther gravity
Kai Lin, Wei-Liang Qian, Alan B. Pavan +2
This paper studies axial gravitational perturbations of a uniform-density star in scalar-Einstein-Ãther theory. By applying the Israel junction conditions explicitly in the presen…
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…
