Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Microphysical and non-thermal processes in the circumgalactic medium: turbulence, magnetic fields and cosmic rays
银河系 周介质 微物理 非热过程 湍流 磁场 宇宙射线
2023/4/18
Multiphase gas structure is ubiquitous in our universe. Recent observations suggest that large quantities of cool (10^4 K) gas are detected in the circumgalactic medium (CGM) of galaxy halos, which ex...
Millions of cosmic rays bombard the Earth’s atmosphere every second. These are naturally-occurring particles from outer space, which are extremely difficult to detect and measure. When they collide wi...
It is a great pleasure and an honor to extend to you a warm invitation to attend the 35th International Cosmic Ray Conference 2017(ICRC2017) at the Busan Exhibition & Convention Center (BEXCO) in Busa...
Cosmic alignment of the aether

2010/12/20
In Einstein-aether theory and Horava gravity, a timelike unit vector is coupled to the spacetime metric. It has previously been shown that in an exponentially expanding homogeneous, isotropic backgrou...
Studies of the performance of the ATLAS detector using cosmic-ray muons
Studies performance ATLAS detector cosmic-ray muons
2011/1/6
Muons from cosmic-ray interactions in the atmosphere provide a high-statistics source of particles that can be used to study the performance and calibration of the ATLAS detector.
In Einstein-aether theory and Horava gravity, a timelike unit vector is coupled to the spacetime metric. It has previously been shown that in an exponentially expanding homogeneous, isotropic backgrou...
A central theme in cosmology is the perplexing fact that the Universe is undergoing an accelerating expansion. The latter, one of the most important and challenging current problems in cosmology, rep...
Unified cosmic history in modified gravity: from F(R) theory to Lorentz non-invariant models
Unified cosmic history modified gravity
2010/12/24
Classical generalization of general relativity is considered as gravitational alternative for unified description of the early-time inflation with late-time cosmic acceleration. The structure and cosm...
The regular cosmic string in Born-Infeld gravity
The regular cosmic string Born-Infeld gravity
2010/12/27
It is shown that Born-Infeld gravity --a high energy deformation of Einstein gravity-- removes the singularities of a cosmic string. The respective vacuum solution results to be free of conical singul...
Cosmic Sum Rules
Cosmic Sum Rules
2010/12/24
We introduce new sum rules allowing to determine universal properties of the unknown component of the cosmic rays and show how it can be used to predict the positron fraction at energies not yet explo...
Modeling high-energy cosmic ray induced terrestrial muon flux: A lookup table
Modeling high-energy cosmic ray induced terrestrial muon flux
2010/12/27
On geological timescales, the Earth is likely to be exposed to an increased flux of high energy cosmic rays (HECRs) from astrophysical sources such as nearby supernovae, gamma ray bursts or by galacti...
We study the quantum stabilization of a cosmic string by a heavy fermion doublet in a reduced version of the standard model. We show that charged strings, obtained by populating fermionic bound state ...

Cosmic Jets General Relativity
2010/12/27
We discuss time-dependent gravitational fields that "accelerate" free test particles to the speed of light resulting in cosmic double-jet configurations. It turns out that complete gravitational coll...
Level Crossing Analysis of Cosmic Microwave Background Radiation: A method for detecting cosmic strings
Cosmic Microwave Background Radiation detecting cosmic strings
2010/12/27
In this paper we study the footprint of cosmic string as the topological defects in the very early universe on the cosmic microwave background radiation. We develop the method of level crossing analy...
