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...
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....
