ck Holes: Unexpected Plasmas, Relevant and Laboratory Based Theories=20
The in situ exploration of the Heliosphere has revealed the existence of un=
expected kinds of plasmas and magnetic field configurations around the most=
distant planets (e.g. Uranus and Neptune) for which reliable theories can =
be formulated and be of help to envision the environments of a variety of r=
ecently discovered exo-planets. On larger scales, radically different kinds=
of plasmas have been found: in particular plasmas with =E2=80=9Ctemperatur=
es in the tens of keV are observed to be the main visible component of Gala=
xy Clusters, while =CE=B3-ray emitting plasma structures (=E2=80=9Cbubbles=
=E2=80=9D) have been seen to emerge from the disk of Our Galaxy with dimens=
ions of the same order as those characterizing the Galaxy. Although the the=
ory of the plasmas that can surround pulsars has a long history, the fact t=
hat the plasmas on the surface of pulsars can have inhomogeneous features (=
such as hot spots) and dynamics has gained attention recently. Given the ve=
ry high magnetic fields involved, the role of the electron thermal conducti=
vity anisotropy is shown to be an important factor in these. There are impo=
rtant issues to be resolved in order to envision the plasmas that can surro=
und black holes. These involve the structures that can form, such as rings =
and 3D spirals, the kind of transport of angular momentum that is needed to=
allow plasma accretion on the black hole, etc. In fact, laboratory experim=
ents on high-energy plasmas have cast new light on basic processes that inc=
lude the nature of angular momentum transport not described by a diffusion =
equation, magnetic reconnection events and associated production of high-en=
ergy particles, self-organization processes, etc.=20

ploration of the Heliosphere has revealed the existence of unexpected kinds=
of plasmas and magnetic field configurations around the most distant plane=
ts (e.g. Uranus and Neptune) for which reliable theories can be formulated =
and be of help to envision the environments of a variety of recently discov=
ered exo-planets. On larger scales, radically different kinds of plasmas ha=
ve been found: in particular plasmas with =E2=80=9Ctemperatures in the tens=
of keV are observed to be the main visible component of Galaxy Clusters, w=
hile =CE=B3-ray emitting plasma structures (=E2=80=9Cbubbles=E2=80=9D)=
have been seen to emerge from the disk of Our Galaxy with dimensions of th=
e same order as those characterizing the Galaxy. Although the theory of the=
plasmas that can surround pulsars has a long history, the fact that the pl=
asmas on the surface of pulsars can have inhomogeneous features (such =
as hot spots) and dynamics has gained attention recently. Given the very hi=
gh magnetic fields involved, the role of the electron thermal conductivity =
anisotropy is shown to be an important factor in these. <span style=3D=
"font-size: 12pt;" data-mce-style=3D"font-size: 12pt;">There are important =
issues to be resolved in order to envision the plasmas that can surround bl=
ack holes. These involve the structures that can form, such as rings and 3D=
spirals, the kind of transport of angular momentum that is needed to allow=
plasma accretion on the black hole, etc. In fact, laboratory experiments o=
n high-energy plasmas have cast new light on basic processes that include t=
he nature of angular momentum transport not described by a diffusion equati=
on, magnetic reconnection events and associated production of high-energy p=
articles, self-organization processes, etc.</span></p></div><div title=3D"P=
