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

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...
Fusion, which promises practically unlimited, carbon-free energy using the same processes that power the sun, is at the heart of a worldwide research effort that could help mitigate climate change.
Turbulence gets eagles up to speed

Most sensible air travelers dread turbulence. A little atmospheric hiccup can shake airplanes, rattle nerves and spill beverages. A Cornell-led collaboration has found that birds don’t mind at all.
Turbulence is everywhere -- it rattles our airplanes and makes tiny whirlpools in our bathtubs -- but it's one of the least understood phenomena in physics.Turbulence occurs when an ordered fluid flow...

2016/5/18
Direct numerical simulations of scalar fields produced by uniform and line sources in channel flow are used as the basis for examining the accuracy of random flight and closure models in predicting tu...

Extreme Turbulence Roiling Most Luminous Galaxy the Universe
2016/1/22
The most luminous galaxy in the Universe – a so-called obscured quasar 12.4 billion light-years away – is so violently turbulent that it may eventually jettison its entire supply of star-forming gas, ...

The most luminous galaxy in the Universe – a so-called obscured quasar 12.4 billion light-years away – is so violently turbulent that it may eventually jettison its entire supply of star-forming gas, ...
As anyone who has experienced turbulence knows, its onset and departure are abrupt, and how long it lasts seems to be unpredictable. Fast flowing fluids are always turbulent, but at slower speeds the ...
Investigations on convective boundary layer turbulence using SODAR data
convective boundary layer acoustic sounding turbulence
2015/9/16
Acoustic sounding (SODAR) data collected in convective conditions were analysed to estimate high order
statistics of the vertical velocity in the lower half of the Convective Boundary Layer (CBL). Li...
Extremely low frequency plasma turbulence recorded by the DEMETER satellite in the ionosphere over the Abruzzi region prior to the April 6, 2009, L’Aquila earthquake
ionosphere turbulence earthquake
2015/8/24
The present study analyzes the low frequency fluctuations of the magnetic and electric fields prior to the earthquake with magnitude M.6.3 on April 6, 2009, in the Abruzzi region in Italy. This includ...
Ionospheric turbulence from ground-based and satellite VLF/LF transmitter signal observations for the Simushir earthquake (November 15, 2006)
VLF/LF signal propagation Eartquake precursors
2015/8/24
Signals from very low frequency (VLF)/ low frequency (LF) transmitters recorded on the ground station at Petropavlovsk-Kamchatsky and on board the French DEMETER satellite were analyzed for the Simush...
