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...
Infrared and radio study of the W43 cluster: resolved binaries and non-thermal emission
Stars: binaries – Stars: Wolf-Rayet – X-rays: stars – Radio continuum: stars – Gamma rays: stars – Infrared: stars
2011/10/9
Context: The recent detection of very high-energy (VHE) gamma-ray emission from the direction of the W43 star-forming region prompted us to investigate its stellar population in detail in an attempt t...
Non-thermal Processes in Black-Hole-Jet Magnetospheres
Black Hole Magnetosphere Particle Acceleration Radiation Mechanism Gamma-Rays Cosmic Rays
2011/10/8
The environs of supermassive black holes are among the universe's most extreme phenomena. Understanding the physical processes occurring in the vicinity of black holes may provide the key to answer a ...
We present a study of the radio emission from a massive runaway star. The star forms a bow shock that is clearly observed in the infrared. We have performed VLA observations under the assumption that ...
Non-thermal emission from galaxy clusters
Cosmology large-scale structure – Galaxies clusters general – Radiation mechanisms non-thermal
2010/11/10
The relevance of non-thermal cluster studies and the importance of combining observations of future radio surveys with WFXT data are discussed in this paper.

Non Thermal Support for the Outer Intracluster Medium
Non Thermal the Outer Intracluster Medium
2011/1/10
We submit that non thermalized support for the outer intracluster medium in relaxed galaxy clusters is provided by turbulence, driven by inflows of intergalactic gas across the virial accretion shocks...
Interpretation of the microwave non-thermal radiation of the Moon during impact events

2009/12/14
The results of recent observations of the non-thermal electromagnetic (EM) emission at wavelengths of 2.5cm, 13cm, and 21cm are summarized. After strong impacts of meteorites or spacecrafts (Lunar Pro...
A universal mirror wave-mode threshold condition for non-thermal space plasma environments
universal mirror wave-mode threshold condition non-thermal space plasma environments
2009/11/12
Magnetic fluctuations are recognized in a large variety of space plasmas by increasingly high resolution, in situ observations as mirror wave mode structures. A typical requirement for the excitation ...
Electron acoustic solitary waves with non-thermal distribution of electrons
Electron acoustic solitary waves non-thermal distribution of electrons
2009/11/11
Electron-acoustic solitary waves are studied in an unmagnetized plasma consisting of non-thermally distributed electrons, fluid cold electrons and ions. The Sagdeev pseudo-potential technique is used ...
Non-thermal Hawking radiation from the Kerr black hole
black hole Hawking radiation Damour-Ruffini method quantum theory
2009/8/14
We present a short and direct derivation of Hawking radiation by using the Damour-Ruffini method, as taking into account the self-gravitational interaction from the Kerr black hole. It is found that t...
