We study the collective modes of gluons in an anisotropic thermal medium presence a constant background magnetic field using hard-thermal-loop perturbation theory. The momentum space anisotropy has been incorporated through generalized Romatschke-Strickland form distribution function, whereas modification arising from quark loop contribution taken into account lowest Landau level approximation....

Abstract Using measurements of the [O iii ], H α , and [N ii ] emission line fluxes originating in cool ( T ∼10 4 K) gas that populates halos massive early-type galaxies with stellar masses greater than 10 10.4 M ⊙ we explore recent conjecture active galactic nucleus (AGN) activity preferentially removes circumgalactic medium (CGM) along polar (minor-axis) direction. We find deficits mean flux ...
