Features of collisionless turbulence in the intracluster medium from simulated Faraday rotation maps II: the effects of instabilities feedback
R. Santos-Lima, E. M. de Gouveia Dal Pino, D. A. Falceta-Gonçalves +2
Statistical analysis of Faraday Rotation Measure (RM) maps of the intracluster medium (ICM) of galaxy clusters provides a unique tool to evaluate some spatial features of the magne…
Features of collisionless turbulence in the intracluster medium from simulated Faraday Rotation maps
M. S. Nakwacki, G. Kowal, R. Santos-Lima +2
Observations of the intracluster medium (ICM) in galaxy clusters suggest for the presence of turbulence and the magnetic fields existence has been proved through observations of Fa…
Cosmic-ray diffusion in collisionless plasmas including pressure anisotropy
M. S. Nakwacki, J. Peralta-Ramos
Using a hybrid kinetic magnetohydrodynamic formalism incorporating the effects of pressure anisotropy, we simulate the evolution of a turbulent collisionless plasma in six differen…
Magnetic field amplification and evolution in turbulent collisionless MHD: an application to the ICM
R. Santos-Lima, E. M. de Gouveia Dal Pino, G. Kowal +3
The amplification and maintenance of the observed magnetic fields in the ICM are usually attributed to the turbulent dynamo action. This is generally derived employing a collisiona…
Production of thermal photons in a simple chiral-hydrodynamic model
J. Peralta-Ramos, M. S. Nakwacki
We use a self-consistent chiral-hydrodynamic formalism which combines the linear model with second-order hydrodynamics in 2+1 dimensions to compute the spectrum of thermal phot…
The role of pressure anisotropy in the turbulent intracluster medium
M. S. Nakwacki, E. M. de Gouveia Dal Pino, G. Kowal +1
In low-density plasma environments, such as the intracluster medium (ICM), the Larmour frequency is much larger than the ion-ion collision frequency. In such a case, the thermal pr…
Characterizing the magnetic field in the intracluster medium
M. S. Nakwacki, E. M. de Gouveia Dal Pino, G. Kowal +1
During structure formation, energetic events and random motions of the hot gas residing inside galaxy clusters (the intracluster medium, ICM) generate turbulent motions. Radio diff…
Production of thermal photons in viscous fluid dynamics with temperature-dependent shear viscosity
J. Peralta-Ramos, M. S. Nakwacki
We compute the spectrum of thermal photons created in Au+Au collisions at GeV, taking into account dissipative corrections in production processes corresponding…
Dynamical evolution of a magnetic cloud from the Sun to 5.4 AU
M. S. Nakwacki, S. Dasso, P. Démoulin +2
Magnetic Clouds (MCs) are a particular subset of Interplanetary Coronal Mass Ejections (ICMEs), forming large scale magnetic flux ropes. In this work we analyze the evolution of a…
Magnetothermal instabilities in magnetized anisotropic plasmas
M. S. Nakwacki, J. Peralta-Ramos
Using the transport equations for an ideal anisotropic collisionless plasma derived from the Vlasov equation by the 16-moment method, we analyse the influence of pressure anisotrop…
Thermal photon production in Au+Au collisions: viscous corrections in two different hydrodynamic formalisms
J. Peralta-Ramos, M. S. Nakwacki
We calculate the spectra of produced thermal photons in Au+Au collisions taking into account the nonequilibrium contribution to photon production due to finite shear viscosity. The…
Progressive transformation of a flux rope to an ICME
S. Dasso, M. S. Nakwacki, P. Démoulin +1
The solar wind conditions at one astronomical unit (AU) can be strongly disturbed by the interplanetary coronal mass ejections (ICMEs). A subset, called magnetic clouds (MCs), is f…
