The 21 cm line of neutral hydrogen (H
I
) opens a new avenue in our exploration of the structure and evolution of the Universe. It provides complementary data to the current large-scale structure (LSS) observations with different systematics, and thus it will be used to improve our understanding of the Λ cold dark matter (ΛCDM) model. This will ultimately constrain our cosmological models, attack unresolved tensions, and test our cosmological paradigm. Among several radio cosmological surveys designed to measure this line, BINGO is a single-dish telescope mainly designed to detect baryon acoustic oscillations (BAOs) at low redshifts (0.127 <
z
< 0.449).
Aims.
Our goal is to assess the fiducial BINGO setup and its capabilities of constraining the cosmological parameters, and to analyze the effect of different instrument configurations.
Methods.
We used the 21 cm angular power spectra to extract cosmological information about the H
I
signal and the Fisher matrix formalism to study BINGO’s projected constraining power.
Results.
We used the Phase 1 fiducial configuration of the BINGO telescope to perform our cosmological forecasts. In addition, we investigated the impact of several instrumental setups, taking into account some instrumental systematics, and different cosmological models. Combining BINGO with
Planck
temperature and polarization data, the projected constraint improves from a 13% and 25% precision measurement at the 68% confidence level with
Planck
only to 1% and 3% for the Hubble constant and the dark energy (DE) equation of state (EoS), respectively, within the
w
CDM model. Assuming a Chevallier–Polarski–Linder (CPL) parameterization, the EoS parameters have standard deviations given by
σ
w
0
= 0.30 and
σ
w
a
= 1.2, which are improvements on the order of 30% with respect to
Planck
alone. We also compared BINGO’s fiducial forecast with future SKA measurements and found that, although it will not provide competitive constraints on the DE EoS, significant information about H
I
distribution can be acquired. We can access information about the H
I
density and bias, obtaining ∼8.5% and ∼6% precision, respectively, assuming they vary with redshift at three independent bins. BINGO can also help constrain alternative models, such as interacting dark energy and modified gravity models, improving the cosmological constraints significantly.
Conclusions.
The fiducial BINGO configuration will be able to extract significant cosmological information from the H
I
distribution and provide constraints competitive with current and future cosmological surveys. It will also help in understanding the H
I
physics and systematic effects.</description><identifier>ISSN: 0004-6361</identifier><identifier>EISSN: 1432-0746</identifier><identifier>DOI: 10.1051/0004-6361/202140888</identifier><language>eng</language><ispartof>Astronomy and astrophysics (Berlin), 2022-08, Vol.664, p.A20</ispartof><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><cites>FETCH-LOGICAL-c199t-8150c259b27246ff0b4accad63dd7a40e11bf0615d2048d0d0f869e36a4b01713</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,776,780,27903,27904</link.rule.ids></links><search><creatorcontrib>Costa, Andre A.</creatorcontrib><creatorcontrib>Landim, Ricardo G.</creatorcontrib><creatorcontrib>Novaes, Camila P.</creatorcontrib><creatorcontrib>Xiao, Linfeng</creatorcontrib><creatorcontrib>Ferreira, Elisa G.
