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…
An Ultra-long Wavelength Sky Model with Absorption Effect
Yanping Cong, Bin Yue, Yidong Xu +3
The radio sky at frequencies below MHz is still largely unknown, this remains the last unexplored part of the electromagnetic spectrum in astronomy. The upcoming space exp…
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…
HIR4: Cosmological signatures imprinted on the cross correlation between 21-cm map and galaxy clustering
Feng Shi, Yong-Seon Song, Jacobo Asorey +5
We explore the cosmological multitracer synergies between an emission line galaxy distribution from the Dark Energy Spectroscopic Instrument and a Tianlai Project 21-cm intensity m…
HIR4: cosmology from a simulated neutral hydrogen full sky using Horizon Run 4
Jacobo Asorey, David Parkinson, Feng Shi +6
The distribution of cosmological neutral hydrogen will provide a new window into the large-scale structure of the Universe with the next generation of radio telescopes and surveys.…
A Radio Burst Detection Method Based on the Hough Transform
Shifan Zuo, Xuelei Chen
We present a simple and fast method for incoherent dedispersion and fast radio burst (FRB) detection based on the Hough transform, which is widely used for feature extraction in im…
