Upper limits on microhertz gravitational waves from supermassive black-hole binaries using PSR J1909-3744 data from the second IPTA data release
Jing Zou, Jingbo Wang Jianping Yuan, De Zhao +4
We present the results of a search for gravitational waves (GWs) from individual sources using high-cadence observations of PSR J1909\(-\)3744 obtained during an intensive observin…

Study of Four nulling pulsars with FAST
Jingbo Wang, Jintao Xie, Jing Zou +1
We present an analysis of 4 nulling pulsars with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). For PSR J1649+2533, our results suggest mode changing rather than…

Long-Term Timing Analysis of PSR J1741-3016: Efficient Noise Characterization Using PINT
Yirong Wen, Jingbo Wang, Wenming Yan +4
The stable rotation of young pulsars is often interrupted by two non-deterministic phenomena: glitches and red timing noise. Timing noise provides insights into plasma and nuclear…
