Post-Doctoral Research Associate in Astronomy
I am a post-doctoral research associate at the Institute of Computation Cosmology, Durham University, working with Tom Theuns, Richard Bower, and Carlos Frenk on galaxy simulations. We have recently submitted a numerical method paper on radiative transfer (https://arxiv.org/abs/2102.08404), which will have many potential applications in galaxy simulations.
I was a physics graduate student at the University of California, San Diego, working with Dusan Keres. We are parts of the Feedback In Realistic Environment (FIRE) collaboration, which focuses on high resolution cosmological simulations with comprehensive stellar feedback.
During my master degree, I worked on gravitational waves and the properties of compact objects with Professor PT Leung in the Chinese University of Hong Kong.
I specialise in numerical methods, parallel computing (C, fortran, and MPI) and data analysis (python).
Radiative Transfer
Simulating radiation propagation is important for stars, galaxies, and cosmology. We developed a novel radiative transfer method that treats radiation as a fluid. See the method paper in MNRAS (arXiv).
Dark Matter
Dark Matter is invisible matter but it provides strong gravity to hold galaxies. We show galaxies can also shape the dark matter distribution through outflows and contraction. (more…)
Ultra Diffuse Galaxies
Ultra diffuse galaxies are extended and dim galaxies with mysterious origins. We explain their origins with strong outflows and quenching at early times. (more…)
Cosmic Ray feedback
Cosmic rays are highly energetic charged particles. They can regulate gas flows and star formation in galaxies. We constrain their propagation with γ ray observations. (more…)
Oscillations of Compact Stars
Compact stars, e.g. neutral stars, can oscillate at high frequencies. Some of the oscillations can generate gravitational waves. By analysing these oscillations, we can understand the structures of compact stars. (more…)
