Massive stars play important roles in many astrophysical systems by providing the radiative and mechanical energy output. They can also produce black holes and neutron stars when they explode. However...
Light rings (LRs) play an important role in gravitational wave observations and black hole photographs. In this paper, we investigate general features of LRs in stationary, axisymmetric, asymptotical...
Encoded in the atomic ISM is physics crucial to the baryonic cycle, including the formation of molecular clouds and the origin of interstellar turbulence from stellar feedback. Nearby galaxies provide...
Heavy particles can be produced on shell during inflation and leave distinct signals in the correlations of density fluctuations. These signals can be searched for in the future CMB/LSS/21cm observati...
The Planet formation involves complicated MHD processes. Planets are believed to be formed within the proto-planetary disks. The speaker will talk about some of the processes related to the proto-plan...
The Hubble Constant is a measure of the expansion rate of the Universe, but in recent years a dichotomy, or tension at the 5-sigma level, has appeared between its measurement in the early Universe for...
In past century we have learned much about the origin and evolution of the Universe. We now know the Universe is 13.8 billion years old, but its main ingredients remain a mystery: atoms make up only 5...
Jets/winds are ubiquitously in association with different celestial objects. However, most of previous theoretical studies of them rely on numerical calculations, not being able to provide a more conv...
When a star falls sufficiently close to a supermassive black hole, it is disrupted by the enormous tidal forces and then the debris feeds a sudden burst of accretion. Such tidal disruption events (TDE...
Insight-HXMT is China’s first X-ray astronomy satellite and was successfully launched on June 15th, 2017. It carries three sets of collimated X-ray instruments with large effective areas, covering en...
