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…
High Sensitivity Methodologies to Detect Radio Band Gravitational Waves
Wei Hong, Peng He, Tong-Jie Zhang +2
Gravitational waves (GWs) can resonate with magnetic fields through the Gertsenshtein-Zeldovich effect, producing electromagnetic signals at the same frequency. In pulsar magnetosp…
Quasi-periodic oscillations of GHz-band polarization in a black hole
Wei Wang, Jiashi Chen, Pengfu Tian +10
Relativistic jets from accreting black holes (BHs) radiate non-thermal emission which is highly variable in different time scales. Magnetic fields anchored to a rotating BH or accr…
Periodicity of sub-pulses in a radio pulsar
Peng-Fu Tian, Ping Zhang, Wen Yang +2
Pulsars are known to manifest complex phenomena, such as nulling, sub-pulse drifting, and periodicity. Within the purview of this investigation, we have harnessed the wavelet analy…
