The Stellar "Snake"-V: the census within 3 kpc in the Solar Neighborhood
Xiang-Ming Yang, Ju-Yong Zhang, Hai-Jun Tian
We present a Gaia DR3 source-level catalogue of Stellar Snake complexes within 3 kpc of the Sun. We define a Stellar Snake as a mutually coherent association of stellar overdensiti…
Probing the cosmological 21~cm global signal from the Antarctic ice sheet
Shijie Sun, Jiaqin Xu, Minquan Zhou +7
The redshifted 21 cm line, arising from neutral hydrogen, offers a unique probe into the intergalactic medium and the first stars and galaxies formed in the early universe. However…
Measurement of the Primary Beam of the Tianlai Cylindrical Antenna Using an Unmanned Aerial Vehicle
Jixia Li, Nanben Suo, Shenzhe Xu +9
The Tianlai Cylinder Pathfinder Array consists of three adjacent cylindrical reflectors fixed on the ground, each 40 meters long and 15 meters wide, with the cylinder axis oriented…
Design and Implementation of a Scalable Correlator Based on ROACH2+GPU Cluster for Tianlai 96-Dual-Polarization Antenna Array
Zhao Wang, Ji-Xia Li, Ke Zhang +7
The digital correlator is one of the most crucial data processing components of a radio telescope array. With the scale of radio interferometeric array growing, many efforts have b…
The Stellar "Snake" -- II: The Mass Function
Xiang-Ming Yang, Sarah A. Bird, Jiadong Li +8
We present a comprehensive investigation on the mass function (MF) of a snake-like stellar structure in the solar neighbourhood, building on our previous discovery. To ensure the r…
The Tianlai dish array low-z surveys forecasts
Olivier Perdereau, Réza Ansari, Albert Stebbins +23
We present the science case for surveys with the Tianlai dish array interferometer tuned to the frequency range. Starting from a realistic…
The Electromagnetic Characteristics of the Tianlai Cylindrical Pathfinder Array
Shijie Sun, Jixia Li, Fengquan Wu +8
A great challenge for 21 cm intensity mapping experiments is the strong foreground radiation which is orders of magnitude brighter than the 21cm signal. Removal of the foreground t…
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…
Beam Measurements of the Tianlai Dish Radio Telescope using an Unmanned Aerial Vehicle
Juyong Zhang, Jingxin Liu, Fengquan Wu +7
Precision measurement of the beam pattern of an antenna is very important for many applications. While traditionally such measurement is often made in a microwave anechoic chamber…
The Tianlai Cylinder Pathfinder Array: System Functions and Basic Performance Analysis
Jixia Li, Shifan Zuo, Fengquan Wu +35
The Tianlai Cylinder Pathfinder is a radio interferometer array designed to test techniques for 21 cm intensity mapping in the post-reionization Universe, with the ultimate aim of…
Progress in the Construction and Testing of the Tianlai Radio Interferometers
Santanu Das, Christopher J. Anderson, Reza Ansari +44
The Tianlai Pathfinder is designed to demonstrate the feasibility of using a wide field of view radio interferometers to map the density of neutral hydrogen in the Universe after t…
Simulation and Testing of a Linear Array of Modified Four-Square Feed Antennas for the Tianlai Cylindrical Radio Telescope
Aleksander J. Cianciara, Christopher J. Anderson, Xuelei Chen +16
A wide bandwidth, dual polarized, modified four-square antenna is presented as a feed antenna for radio astronomical measurements. A linear array of these antennas is used as a lin…
