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…
FAST Polarization Catalog of FRB 20240114A
Tian-Cong Wang, Jun-Shuo Zhang, Xiao-Hui Liu +60
Polarization measurements of fast radio bursts (FRBs) probe the magnetized plasma surrounding their central engines. FRB~20240114A is an exceptionally active repeating source, with…
A comprehensive search for Long and Short Periodic Features from an Extremely Active Cycle of FRB 20240114A
Dengke Zhou, Pei Wang, Jianhua Fang +56
Possible periodic features in fast radio bursts (FRBs) may provide insights into their astrophysical origins. Using extensive observations from the Five-hundred-meter Aperture Sphe…
Hyper-active repeating fast radio bursts from rotation modulated starquakes on magnetars
Jia-Wei Luo, Jia-Rui Niu, Wei-Yang Wang +13
The non-detection of periodicity related to rotation challenges magnetar models for fast radio bursts (FRBs) with FRB emission from close to the magnetar surface. Moreover, a bimod…
Bright bursts with sub-millisecond structures of FRB 20230607A in a highly magnetized environment
DeJiang Zhou, J. L. Han, Bing Zhang +19
We report the observations of a repeating FRB 20230607A for 15.6 hours spanning 16 months using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) with the detection…
The flat tail in the burst energy distribution of FRB 20240114A
Yu-Xiang Huang, Jun-Shuo Zhang, Heng Xu +19
Fast Radio Bursts (FRBs) are enigmatic millisecond-duration radio transients of extra-galactic origin, whose underlying mechanisms and progenitors remain poorly understood. FRBs ar…
