I am Shi-Jie Gao (高世杰), a postdoctoral researcher at the School of Astronomy and Space Science, Nanjing University.

My work has two main threads: compact-object binary evolution and radio pulsars/transients.

On the theory side, I study how compact-object binaries form and evolve, including X-ray binaries, binary pulsars, and possible channels for mass-gap black holes. On the observational side, I search for radio pulsars and transients with data from FAST, the Green Bank Telescope, and smaller radio telescopes.

I am also working on the 4.5-m radio telescope at Nanjing University’s Zuo Dijiang (左涤江) Observatory, including telescope control, pointing calibration, and an SDR-based pulsar observing terminal.

Research Interests

• Compact-object binaries and X-ray binaries
• Radio pulsars and radio transients

Selected Highlights

• Reported 19 pulsars from FAST archival data in Pulsar Gleaners, named after the idea of recovering overlooked signals.
• Discovered the first radio pulsar associated with the globular cluster Terzan 6, PSR J1750-3116A, using high-frequency Green Bank Telescope data.
• Studied the formation of mass-gap black holes from neutron-star X-ray binaries with super-Eddington accretion.
• Commissioned and tested Nanjing University’s 4.5-m radio telescope for pulsar observing practice.

Background

I studied physics at Shandong University before moving into astronomy and high-energy astrophysics. That training led me toward compact objects.

I like problems where physical modeling meets real data: how compact-object binaries form, how pulsars show up in noisy observations, and what these systems tell us about stellar evolution.
