This paper reports the first pulsar discovery by FAST, demonstrating the effectiveness of their data pipelines during telescope commissioning, and confirming the pulsar with follow-up observations.

## Contribution

The paper introduces the first pulsar discovered by FAST and validates the data acquisition and processing pipelines used during telescope commissioning.

## Key findings

- First pulsar discovered by FAST
- Pulsar named PSR J1900-0134 with 1.8 s period
- Confirmed by Parkes radio telescope

## Abstract

To assist with the commissioning (Jiang et al. 2019) of the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we performed a pulsar search, with the primary goal of developing and testing the pulsar data acquisition and processing pipelines. We tested and used three pipelines, two (P1 and P2 hereafter) searched for the periodic signature of pulsars whereas the other one was used to search for bright single pulses (P3 hereafter). A pulsar candidate was discovered in the observation on the 22nd August, 2017, and later confirmed by the Parkes radio telescope on the 10th September, 2017. This pulsar, named PSR J1900-0134, was the first pulsar discovered by FAST. The pulsar has a pulse period of 1.8 s and a dispersion measure (DM) of 188\,pc\,cm$^{-3}$.
