Forecast on Gravity with HI 21cm Intensity Mapping Surveys
Yanling Song, Yu Sang, Linfeng Xiao +1
Modified gravity theories offer a well-motivated extension of General Relativity and provide a possible explanation for the late-time accelerated expansion of the Universe. Among t…
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…
Void Lensing in Cubic Galileon Gravity
Chen Su, Huanyuan Shan, Jiajun Zhang +6
Weak lensing studies via cosmic voids are a promising probe of Modified Gravity (MG). Excess surface mass density (ESD) is widely used as a lensing statistic in weak lensing resear…
The BINGO Project VII: Cosmological Forecasts from 21cm Intensity Mapping
Andre A. Costa, Ricardo G. Landim, Camila P. Novaes +17
The 21cm line of neutral hydrogen (HI) opens a new avenue in our exploration of the structure and evolution of the Universe. It provides complementary data to the current large-sca…
The BINGO Project I: Baryon Acoustic Oscillations from Integrated Neutral Gas Observations
Elcio Abdalla, Elisa G. M. Ferreira, Ricardo G. Landim +43
Observations of the redshifted 21-cm line of neutral hydrogen (HI) are a new and powerful window of observation that offers us the possibility to map the spatial distribution of co…
Baryon Acoustic Oscillations from Integrated Neutral Gas Observations: an instrument to observe the 21cm hydrogen line in the redshift range 0.13 z 0.45 -- status update
Carlos A. Wuensche, Elcio Abdalla, Filipe Batoni Abdalla +48
BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making th…
Forecasts on Interacting Dark Energy from 21-cm Angular Power Spectrum with BINGO and SKA observations
Linfeng Xiao, Andre A. Costa, Bin Wang
Neutral hydrogen (HI) intensity mapping is a promising technique to probe the large-scale structure of the Universe, improving our understanding on the late-time accelerated expans…
Modelling cosmic ray electron physics in cosmological smoothed particle hydrodynamics simulation
Dongchao Zheng, Weitian Li, Zhenghao Zhu +5
Cosmic ray electron (CRE) acceleration and cooling are important physical processes in astrophysics. We develop an approximative framework to treat CRE physics in the parallel smoo…
Fractional Dark Matter decay: cosmological imprints and observational constraints
Linfeng Xiao, Le Zhang, Rui An +2
If a fraction of the Dark Matter decays into invisible and massless particles (so-called "dark radiation") with the decay rate (or inverse lifetime) ,…
Can Conformal and Disformal Couplings Between Dark Sectors Explain the EDGES 21cm Anomaly?
Linfeng Xiao, Rui An, Le Zhang +3
The recently announced result by EDGES points an unexpected excess in the 21 cm global brightness temperature from cosmic dawn at , potentially indicating new phenomena b…
