Hello there!
Yet another personal website
I’m Feiyu Quan (全飞宇), a PhD student at The Chinese University of Hong Kong Star Formation Group studying astrophysics. Previously, I studied astrophysics at University of Toronto and University of Cambridge.
My research
Projection effects in observations
Feiyu Quan et al., Projection Is All You Need: Interpreting Polarization Measurements in the Orion Clouds with Sub-Alfvénic MHD Simulations, The Astrophysical Journal, 2026, doi link.
This work discusses the significance of projection effects in interpreting observations of polarizations, and the complex magentic field morphologies in slightly super-Alfvénic dense cores within sub-Alfvénic molecular clouds. Interactive visualizations of these cores and their surrounding magnetic fields (from the simulations in this work) can be found at here (for misaligned magnetic fields) and here (for aligned magnetic fields). (They could take a while to load. If they are not loading, clearing your browser’s cache might help.)
In these visualizations, the red field lines indicate that they pass through dense regions with volume density $ > 5 \times 10^4 \ {\rm H_2}\ \mathrm{cm}^{-3} $ , while the blue field lines pass through diffuse gas with volume density $ < 1 \times 10^4 \ {\rm H_2}\ \mathrm{cm}^{-3} $. The grey-scale color indicates different volume densities.
