Other Research Interests

I am also interested in many other directions in astrophysics. I have worked on and published papers in the following fields:

* Radiation mechanisms of broad-band emission of rotation-powered (radio and gamma-ray pulsars) and magnetic-powered (magnetars) neutron stars.
* Strange quark stars, their formation, and possible observational signatures.
* Black holes and accretion disks, jet launching, baryon loading, instability, role of magnetic fields, and neutrino emission.
* Relativistic MHD and particle-in-cell numerical simulations on jet launching and propagation, particle acceleration and radiation.
* Charged black holes, their neutralization and observational signatures.
* Primordial black holes, their accretion and evaporation history.
* Active galactic nuclei, especially the so-called blazars, their emission properties, jet launching mechanism, and relation to GRB jets.
* Tidal disruption events, especially the sources that produce relativistic jets.
* Supernovae and general cosmic explosions, their photosphere evolution.
* White dwarf pulsars, both spindown-powered and binary-interaction-powered.
* Cosmic rays, from 100 TeV to ultra-high-energy cosmic rays (UHECRs).
* High energy neutrinos, their production from GRBs and magnetars, neutrino oscillation and implications of Glashow resonance.
* Dark matter, indirect detection, its relation to gamma-ray and electron/positron spectral excesses. Dark stars and observational constraints.
* Using astrophysical probes (GRBs, FRBs, GWs, neutrinos) to constrain baryon mass density, dark matter, dark energy, large-scale structure, and fundamental physics (Lorentz invariance violation, weak equivalence principle, photon mass, etc.).
* Gravitational lensing, application to FRBs and constraints on Hubble constant and other cosmological parameters.
* Astrophysical turbulence and its applications in interstellar medium, pulsars, FRBs, GRBs, and pulsar wind nebulae.
* Exoplanets, radiation signature of collisions among themselves and with host stars.
* Collisions between comets/asteroids with neutron stars and even strange stars.
* Relativistic astronomy: using trans-relativistic cameras to observe the universe and test fundamental physics.
* Habitable galaxies in high-redshift universe.
