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…
On the relative CNO underabundance in quasar absorption systems at arising from Population III enrichment and attenuation by intermediate-mass black holes and primordial baryon accretion
Murilo Macedo, Carlos Alexandre Wuensche, Oswaldo Duarte Miranda
This article uses an adapted version of the semi-analytical model of cosmic chemical enrichment developed by \citet{Corazza_2022} to reproduce the observed abundances of C, N, and…
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…
Cosmographic constraints from late-time probes including fast radio bursts
Lázaro L. Sales, Klecio E. L. de Farias, Amilcar R. Queiroz +7
In this study, we use late-time probes, such as well-localized fast radio bursts (FRBs), baryon acoustic oscillations (BAO), supernovae (SNe), and cosmic chronometers (CC) to const…
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…
