CosmicWeb-21cm array: A New Radio Observation Array Design for 21cm Cosmology
Jiancheng Wang, Jirong Mao, Xiangming Cheng +10
This paper presents the CosmicWeb-21cm array, a novel radio interferometer designed to overcome the key challenges in 21 cm cosmology. Its core innovations include: (1) a multi-sca…
The Chinese Pulsar Timing Array data release I. Single pulsar noise analysis
Siyuan Chen, Heng Xu, Yanjun Guo +23
The Chinese Pulsar Timing Array (CPTA) has collected observations from 57 millisecond pulsars using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) for close to th…
Precision Determination of Scintillation Screen Parameters from Annual Modulation Measurement of Pulsar Scintillation Arc Curvature with the FAST Telescope
Yuanshang Huang, Xun Shi, Jumei Yao +2
Pulsar scintillation observations have revealed ubiquitous discrete scintillation screens in the interstellar medium. A major obstacle in identifying the nature of these screens is…
A Linear Decomposition Method to Analyze and Study Pulsar Mode Changes
Longfei Hao, Zhixuan Li, Faxin Shen +5
In this paper, we present the linear decomposition method (LDM), which we developed to detect and analyze pulsar profile variations and mode changing behaviour. We developed LDM ut…
The Chinese pulsar timing array data release I. Polarimetry for 56 millisecond pulsars
Jiangwei Xu, Jinchen Jiang, Heng Xu +27
We present polarization pulse profiles for 56 millisecond pulsars (MSPs) monitored by the Chinese Pulsar Timing Array (CPTA) collaboration using the Five-hundred-meter Aperture Sph…
Ninety percent circular polarization detected in a repeating fast radio burst
J. C. Jiang, J. W. Xu, J. R. Niu +34
Fast radio bursts (FRBs) are extra-galactic sources with unknown physical mechanisms. They emit millisecond-duration radio pulses with isotropic equivalent energy of $10^{36}\sim10…
Scintillation velocity and arc observations of FRB 20201124A
Ziwei Wu, Weiwei Zhu, Bing Zhang +18
We present the scintillation velocity measurements of FRB~20201124A from the FAST observations, which reveal an annual variation. This annual variation is further supported by chan…
Radio Frequency Interference Detection Using Efficient Multi-Scale Convolutional Attention UNet
Fei Gu, Longfei Hao, Bo Liang +6
Studying the universe through radio telescope observation is crucial. However, radio telescopes capture not only signals from the universe but also various interfering signals, kno…
