Research Highlights: 

As a theoriest my primary interest is in high-energy astrophysics and cosmology. My research has touched many fields in astrophysics and cosmology, including gamma-ray bursts, supernovae, black holes, accretion disks, gravitational lensing, creation of the universe and time travel. With Bohdan Paczynski, I proposed the model of mini-supernovae, as outcome of neutron star-neutron star or black hole-neutron star mergers. The model is being used to constrain models for short gamma-ray bursts. Richard Gott and I proposed a model for the self-creation of the Universe, in which the Universe started from an epoch with closed timelike curves so that time has no beginning. With Ramesh Narayan et al., I developed a program KERRBB for caculating the blackbody spectrum of a relativistic accretion disk around a Kerr black hole, which becomes a standard tool for fitting the spectra of X-ray binaries and determing the spin parameter of black holes. I am currently involved in the SVOM and Einstein-Probe projects and responsible for theoretical study on supernova shock-breakout, high-redshift gamma-ray bursts, and mini-supernova.
