Discovery and Timing Follow-Up of Two FAST-Discovered Pulsars from the FAST CRAFTS Survey
Victoria A. Blackmon, Maura A. McLaughlin, De Zhao +6
We present the results of Green Bank Telescope (GBT) observations of two pulsars discovered with the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) during the 19-beam…
Flux Variations of Fast Radio Bursts and Their Persistent Radio Sources: Evidence for a Shared Progenitor
Xinming Li, Chenhui Niu, Jiaheng Zhang +24
Fast radio bursts (FRBs) are millisecond-duration extragalactic radio transients, some of which are associated with compact persistent radio sources (PRSs), hinting at a physical c…
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.…
A Python/CuPy Software Correlator for QUEST: Real-Time Performance and Initial Imaging
Jialang Ding, Guanhong Lin, Dejia Zhou +20
We present a Python/CuPy FX software correlator for small radio interferometer arrays and evaluate it on QUEST (Qilu University Explorer Survey Telescope). The system combines mult…
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…
A 44-minute periodic radio transient in a supernova remnant
Di Li, Mao Yuan, Lin Wu +45
Long-period radio transients (LPTs) are a newly discovered class of radio emitters with periods ranging from minutes to hours. The astrophysical nature remains undetermined, partic…
