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...
A major uncertainty in the determination of the mass profile of the Milky Way using stellar kinematics is the poorly determined anisotropy parameter, beta = 1 - ( ( (sigma_theta)**2 + (sigma_phi)**2 )...
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...
Wide-field radio-interferometer surveys at high resolution, relatively low frequency and with very high dynamic range requirement play a prominent role in current and forthcoming radio astronomy progr...
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...
Brown dwarfs and relatively isolated young extrasolar giant planets occupy an important parameter space to understand planetary atmospheres. Recent observations of these worlds have provided unprecede...
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...
