Indication for Decreasing Dispersion Measure in the Population of Repeating Fast Radio Bursts and Connection to Young Supernova Remnant Expansion

Xiang-han Cui, Cheng-min Zhang, Di Li +9

Fast Radio Bursts (FRBs) are millisecond-duration, highly energetic radio transients of uncertain origin. Repeating FRBs provide an excellent population for investigating their nat…

Cross-validation of six dispersion measure estimation methods for FRB 20240114A

Tonglun Wang, Songbo Zhang, Yuanchuan Zou +11

Fast Radio Bursts (FRBs) are important cosmological probes, but their applications depend critically on accurate dispersion measure (DM) determinations. We present a systematic com…

Fast radio bursts, magnetars and earthquakes: their "family feud"?

Si-Lu Xu, Yong-Kun Zhang, Pei Wang +24

Fast radio bursts (FRBs) are millisecond-duration cosmic transients whose origin remains elusive. Competing models invoke either earthquake-like processes or flare-like mechanisms.…

FRTSearch: Unified Detection and Parameter Inference of Fast Radio Transients using Instance Segmentation

Bin Zhang, Yabiao Wang, Xiaoyao Xie +11

The exponential growth of data from modern radio telescopes presents a significant challenge to traditional single-pulse search algorithms, which are computationally intensive and…

Identifying Quasi-Periodic Micropulses in Pulsars with FAST Using Convolutional Neural Networks

Shidong Wang, Hui Liu, Ru-Shuang Zhao +12

Quasi-periodic MicroPulses (QMP) are quasi-periodic microstructural features manifested in individual pulsar radio pulses, the study of which is crucial for understanding pulsar ra…

Multi-Faceted Emission Properties of PSR J2129+4119 Observed with FAST

Habtamu Menberu Tedila, Di Li, Pei Wang +10

We present a detailed single-pulse study of the long-period pulsar PSR J2129+4119 using high-sensitivity FAST observations. Despite locating well below the traditional death line,…
