Find new pulsars in Globular Clusters with the Fast Fold Algorithm

Li, Yaowei

The globular clusters， famous as pulsar factories， contain a large number of pulsars. Most of them are millisecond pulsars， but there are few long-period pulsars. The sensitivity of the fast folding algorithm (FFA) is higher than the Fast Fourier Transform (FFT)， especially for long-period pulsars. We used the FFA to search for partial observations of globular clusters within the FAST sky. With the FFA， we found a new pulsar in M13.
