High-ion absorption in the proximate damped Lyman-alpha system toward Q0841+129
quasars: absorption lines – galaxies: high-redshift – galaxies: halos – galaxies: ISM
2011/10/8
We present VLT/UVES spectroscopy of the quasar Q0841+129, whose spectrum shows a proximate damped Lyman-alpha (PDLA) absorber at z=2.47621 and a proximate sub-DLA at z=2.50620, both lying close in red...

Using the extended Poincar\'{e}-Lighthill-Kuo (PLK) reductive perturbation method to study the small-amplitude ion acoustic solitary wave (IASW) dynamics (propagation and interaction), it is shown tha...

Anisotropic unstable ion distribution functions downstream of the solar wind termination shock
ion plasma state solar wind
2009/5/27
In this paper we demonstrate that solar wind ions, passing over the quasiperpendicular portion of the solar wind MHD termination shock, unavoidably develop strongly pronounced pitchangle anisotropies....
