I am Shi-Jie Gao (高世杰), a postdoctoral researcher at the School of Astronomy and Space Science, Nanjing University. My research currently follows two distinct directions: theoretical studies of the formation and evolution of compact-object binaries, and radio observations of pulsars and transients. In future work, I aim to connect these theoretical and observational directions.

Research Focus

Compact-object binaries. I study how compact-object and X-ray binaries form and evolve, with interests spanning binary pulsars, white-dwarf binaries, and possible formation channels for mass-gap black holes.

Radio pulsars and transients. My current work emphasizes pulsar and transient searches and pulsar polarization studies using FAST, the Green Bank Telescope, and the Parkes 64-m radio telescope (Murriyang).

Selected Highlights

• Detected more than 30 pulsars in FAST data; the Pulsar Gleaners page lists those identified in publicly available FAST observations.
• Discovered PSR J1750-3116A, the first radio pulsar associated with the globular cluster Terzan 6, through a direct high-frequency search with the Green Bank Telescope.
• Studied RRAT J2325-0530, a rotating radio transient with an atypical waiting-time distribution.
• Investigated compact-object binary evolution and possible routes to forming mass-gap black holes.
• Helped commission Nanjing University’s 4.5-m radio telescope and detect signals from eight pulsars for teaching and public outreach.

Background

I studied physics at Shandong University and completed my Ph.D. in astronomy at Nanjing University. My doctoral research focused on compact-object and X-ray binary evolution; my postdoctoral work places greater emphasis on radio pulsar and transient searches.

I enjoy problems where physical modeling meets real data: how compact-object binaries form, how weak pulsar signals emerge from noisy observations, and what these systems reveal about stellar evolution.
