About Us

We are the Astrophysics and Space Technology Laboratory (ASTL) at the Department of Physics, National Changhua University of Education, Taiwan. 

Our research focuses on high-energy and multi-messenger astrophysics, especially compact objects and transient phenomena. We study neutron stars, black holes, magnetars, fast radio bursts, X-ray binaries, and other high-energy sources. Our group combines multi-wavelength observations and advanced data-analysis methods to investigate the physical processes around compact objects.

We are also involved in the development of space-based X-ray and gamma-ray instruments. Our current activities include CubeSat science missions, scientific payloads, detector development, and readout systems. These projects provide opportunities for students to work on both astrophysical research and space technology. Our main research topics include:

1. High-energy and multi-messenger astrophysics

   • Magnetars, fast radio bursts, and neutron-star physics

   • Multi-wavelength observations of transient sources

   • X-ray polarization and strong-field quantum electrodynamics

   • Gravitational-wave sources and transient signals

2. Accretion physics around compact objects

   • X-ray binaries, ultraluminous X-ray sources, and active galactic nuclei

   • Long-term variability and superorbital modulation

   • Spin evolution of accreting neutron stars

   • Accretion geometry and spectral-timing evolution

3. Advanced data analysis methods

   • Timing and time-frequency analysis of non-stationary signals

   • Machine-learning methods for detection, classification, and prediction

4. Space technology and instrumentation

   • X-ray and gamma-ray CubeSat missions

   • Scientific payloads for FORMOSAT missions

   • Development of next-generation space-based X-ray detectors

Students in our group can work on observational astronomy, astronomical data analysis, machine learning, detector testing, electronics, or space instrumentation.
