MeerKAT HI observations of Low Surface Brightness/Ultradiffuse Galaxy Candidates Projected around Two Southern Loose Groups
Chandreyee Sengupta, Tom C. Scott, Hao Chen +9
A large catalogue of low surface brightness galaxies (LSBGs) from the Dark Energy Survey showed significant clustering around nearby galaxy groups and clusters. Using the HIPASS su…
In search of an interaction in the dark sector through Gaussian Process and ANN approaches
Mazaharul Abedin, Guo-Jian Wang, Yin-Zhe Ma +1
Whether the current observational data indicate any evidence of interaction between the dark sector is a matter of supreme interest at the present moment. This article searched for…
Expanded Generalized Needlet Internal Linear Combination (eGNILC) Framework for the 21-cm Foreground Removal
Wei-Ming Dai, Yin-Zhe Ma
The Generalized Needlet Internal Linear Combination (GNILC) method is a non-parametric component separation algorithm to remove the foreground contamination of the 21-cm intensity…
HI Intensity Mapping cross-correlation with thermal SZ fluctuations: forecasted cosmological parameters estimation for FAST and Planck
Ayodeji Ibitoye, Furen Deng, Yichao Li +2
The 21 cm emission from neutral hydrogen surveys holds great potential as a valuable method for exploring the large-scale structure of the Universe. In this paper, we forecast for…
Constraining Holographic Dark Energy and Analyzing Cosmological Tensions
Xin Tang, Yin-Zhe Ma, Wei-Ming Dai +1
We investigate cosmological constraints on the holographic dark energy (HDE) using the state-of-the-art cosmological datasets: Planck CMB angular power spectra and weak lensing pow…
Constraining primordial non-Gaussianity using Neural Networks
Chandan G. Nagarajappa, Yin-Zhe Ma
We present a novel approach to estimate the value of primordial non-Gaussianity () parameter directly from the Cosmic Microwave Background (CMB) maps using a convolutio…
