Quantum Field Theoretic Description of Matter in the Universe / Thoma, Markus H. (CERN)
Quantum field theory at finite temperature and density can be used for describing the physics of relativistic plasmas. Such systems are frequently encountered in astrophysical situations, such as the early Universe, Supernova explosions, and the interior of neutron stars. [...]

Laboratory Astrophysics Using High Energy Density Photon and Electron Beams / Bingham, Robert
The development of intense laser and particle beams has opened up new opportunities to study high energy density astrophysical processes in the Laboratory. With even higher laser intensities possible in the near future vacuum polarization processes such as photon - photon scattering with or without large magnetic fields may also be experimentally observed.

Complete nondestructive diagnostic of nonneutral plasmas based on the detection of electrostatic modes / Amoretti, M ; Bonomi, G ; Bouchta, A ; Bowe, P ; Carraro, C ; Cesar, C L ; Charlton, M ; Doser, Michael ; Fontana, A ; Fujiwara, M C et al.
The detection of the electrostatic nonneutral plasma modes in the ATHENA experiment was investigated. A complete nondestructive diagnostic of the plasma based on a fit to the line shape of the function describing the power transmitted through the plasma was developed. [...]

Dispersion Relations in Ultradegenerate Relativistic Plasmas / Manuel, Cristina (CERN)
The propagation of excitation modes in a relativistic ultradegenerate plasma is modified by their interactions with the medium. These modifications can be computed by evaluating their on-shell self-energy, which gives (gauge-independent) dispersion relations. [...]

Jetted GRBs, afterglows and SGRs from quark stars birth / Dar, Arnon (CERN ; Technion)
Recent studies suggest that when cold nuclear matter is compressed to high nuclear densities, diquarks with spin zero and antisymmetric color wave function Bose condensate into a superfluid/superconducting state that is several times as dense. Various astrophysical phenomena may be explained by gravitational collapse of neutron stars (NSs) to (di)quark stars (QSs) as a result of a first order phase transition in NSs within $\sim 10^{4}$ years after their birth in supernova explosions, when they cooled and spun down sufficiently (by magnetic braking ?). [...]

Search for energetic cosmic axions utilizing terrestrial/celestial magnetic fields / Zioutas, Konstantin (Thessaloniki U.) ; Thompson, D J (NASA, Goddard) ; Paschos, E A (Dortmund U.)
Orbiting $\gamma$-detectors combined with the magnetic field of the Earth or the Sun can work parasitically as cosmic axion telescopes. The relatively short field lengths allow the axion-to-photon conversion to be coherent for $m_{axion} \sim 10^{-4}$ eV, if the axion kinetic energy is above $\sim 500$ keV (Earth's field), or, $\sim 50$ MeV (Sun's field), allowing thus to search for axions from $e^+e^-$ annihilations, from supernova explosions, etc. [...]
