Foreground Mitigation and Power Spectrum Analysis for Tianlai Full-Sky 21 cm Survey Observation
Yikai Deng, Shifan Zuo, Jixia Li +2
We present a comprehensive analysis of the 21 cm intensity mapping (IM) data from the Tianlai Cylinder Pathfinder Array (TCPA), focusing on multi-scale foreground mitigation and th…
A Morphological Identification and Study of Radio Galaxies from LoTSS DR2. I. The "Winged'' Radio Galaxies
Soumen Kumar Bera, Taotao Fang, Tapan K. Sasmal +3
We conducted an extensive identification and analysis of various morphological classes and subclasses of radio galaxies using the latest high-resolution data from the second data r…
Constraining Lyman-Werner Feedback from Velocity Acoustic Oscillations in the Cosmic Dawn 21 cm Signal
Xi Du, Bin Yue, Furen Deng +4
During Cosmic Dawn, Pop III stars could be formed in minihalos through molecular hydrogen (H) cooling. The minimum halo mass required for H cooling is highly sensitive to L…
21 cm Power Spectrum Analysis of North Celestial Pole Observations with the Tianlai Dish Pathfinder Array
Guangzhi He, Shifan Zuo, Jixia Li +11
The Tianlai Dish Pathfinder Array (TDPA) is a radio interferometer designed to test techniques for 21 cm intensity mapping in the post-reionization universe as a means of measuring…
Probing power spectrum enhancement at small scales with the SKA
Hourui Zhu, Bin Yue, Yidong Xu +2
The reionization process is driven by ionizing photons from dwarf galaxies in halos with virial temperature K, while minihalos whose $T_{\rm vir}\lesssim…
Primordial black holes and the velocity acoustic oscillations features in 21 cm signals from the cosmic Dark Ages
Zhihe Zhang, Bin Yue, Yidong Xu +2
Astrophysical luminous objects such as the first stars have not yet formed in the Dark Ages. However, primordial black holes (PBHs) always exist throughout cosmic history since the…
Synthesis imaging with a lunar orbit array: II. Impacts of instrument-induced phase errors
Meng Zhou, Furen Deng, Yidong Xu +2
A lunar orbit interferometer array suffers from a number of systematics. Beyond systematics induced by the imaging algorithm itself and thermal noise considered in Paper I, phase e…
