Constraining interacting dark energy models with the halo concentration-mass relation
Yu Zhao, Yun Liu, Shihong Liao +3
The interacting dark energy (IDE) model is a promising alternative cosmological model which has the potential to solve the fine-tuning and coincidence problems by considering the i…
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…
Near-infrared chemical abundances of stars in the Sculptor dwarf galaxy
Baitian Tang, Jiajun Zhang, Zhiqiang Yan +3
Owing to the recent identification of major substructures in our Milky Way (MW), the astronomical community has started to reevaluate the importance of dissolved and existing dwarf…
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 VIII: On the recoverability of the BAO signal on HI intensity mapping simulations
Camila Paiva Novaes, Jiajun Zhang, Eduardo J. de Mericia +17
A new and promising technique for observing the Universe and study the dark sector is the intensity mapping of the redshifted 21cm line of neutral hydrogen (HI). The BINGO radio te…
Improvement of cosmological constraints with the cross correlation between line-of-sight optical galaxy and FRB dispersion measure
Chenghao Zhu, Jiajun Zhang
Fast Radio Bursts (hereafter FRBs) can be used in cosmology by studying the Dispersion Measure (hereafter DM) as a function of redshift. The large scale structure of matter distrib…
