1/f Noise Analysis for FAST HI Intensity Mapping Drift-Scan Experiment
Wenkai Hu, Yichao Li, Yougang Wang +8
We investigate the 1/f noise of the Five-hundred-meter Aperture Spherical Telescope (FAST) receiver system using drift-scan data from an intensity mapping pilot survey. All the 19…
HI intensity mapping with MeerKAT: Calibration pipeline for multi-dish autocorrelation observations
Jingying Wang, Mario G. Santos, Philip Bull +10
While most purpose-built 21cm intensity mapping experiments are close-packed interferometer arrays, general-purpose dish arrays should also be capable of measuring the cosmological…
The Tianlai Dish Pathfinder Array: design, operation and performance of a prototype transit radio interferometer
Fengquan Wu, Jixia Li, Shifan Zuo +34
The Tianlai Dish Pathfinder Array is a radio interferometer designed to test techniques for 21~cm intensity mapping in the post-reionization universe as a means for measuring large…
HI intensity mapping with MeerKAT: 1/f noise analysis
Yichao Li, Mario G. Santos, Keith Grainge +2
The nature of the time correlated noise component (the 1/f noise) of single dish radio telescopes is critical to the detectability of the HI signal in intensity mapping experiments…
Reconstructing the radial velocity profile of cosmic voids with kinematic Sunyaev-Zeldovich Effect
Yi-Chao Li, Yin-Zhe Ma, Seshadri Nadathur
We develop an estimator to extract the mean radial velocity profile of cosmic voids via the kinematic Sunyaev-Zeldovich effect of pairs of galaxies surrounding them. The estimator…
Forecasts of cosmological constraints from HI intensity mapping with FAST, BINGO & SKA-I
Elimboto Yohana, Yi-Chao Li, Yin-Zhe Ma
We forecast the cosmological constraints of the neutral hydrogen (HI) intensity mapping (IM) technique with radio telescopes by assuming 1-year of observational time. The current a…
