Research

My research centers on compact-object binaries and radio pulsars/transients. I use binary-evolution modeling, population synthesis, and radio data analysis to connect how compact objects form with how they are observed.

Compact-Object Binary Evolution

I study compact-object binaries containing neutron stars, black holes, and white dwarfs. My work focuses on how mass transfer, super-Eddington accretion, common-envelope evolution, stellar winds, and compact-object mass growth shape X-ray binaries, binary pulsars, and mass-gap black-hole candidates.

I mainly use MESA/BSE calculations and binary population synthesis, then compare the results with observed systems.

Radio Pulsars and Transients

I search for and characterize radio pulsars and transient radio sources with FAST, the Green Bank Telescope, and the 4.5-m radio telescope at NJU. My work includes periodicity searches, FFA searches, acceleration searches, single-pulse analyses, and polarization data processing.

I am particularly interested in faint, long-period, sporadic, and high-dispersion-measure pulsars. Examples include the FAST archival discoveries in Pulsar Gleaners and PSR J1750-3116A, the first radio pulsar likely associated with Terzan 6.

4.5-m Radio Telescope at NJU

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

This small telescope is a hands-on way to show how pulsar signals are received, recorded, folded, and interpreted.
