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…
FAST H I 21 cm study of blueberry galaxies
Yogesh Chandola, Chao-Wei Tsai, D. J. Saikia +3
Green Peas (GPs) and blueberry galaxies (BBs) are thought to be local analogs (0.1) of high redshift Ly emitters. H I study of these can help us understand the star formatio…
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…
FAST survey of H I and OH absorption towards extragalactic radio sources
Yogesh Chandola, D. J. Saikia, Yin-Zhe Ma +5
Neutral atomic hydrogen and molecular gas in the host galaxies of radio active galactic nuclei (AGN) can be traced using H I 21-cm and OH-1667 MHz absorption lines to understand th…
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…
H I content of selected mid-infrared bright, starburst blue compact dwarf galaxies
Yogesh Chandola, Di Li, Chao-Wei Tsai +10
We report measurements of H I content in 11 nearby, actively star-forming, blue compact dwarf galaxies (BCDs) from 21 cm observations with the Arecibo telescope. These BCDs, select…
