Highly anisotropic and strongly dissipative hydrodynamics for early stages of relativistic heavy-ion collisions

W Florkowski, R Ryblewski - Physical Review C—Nuclear Physics, 2011 - APS
We introduce a new framework of highly anisotropic hydrodynamics that includes dissipation
effects. Dissipation is defined by the form of the entropy source that depends on the pressure …

Kinetic turbulence in relativistic plasma: from thermal bath to nonthermal continuum

V Zhdankin, GR Werner, DA Uzdensky… - Physical Review Letters, 2017 - APS
We present results from particle-in-cell simulations of driven turbulence in magnetized,
collisionless, and relativistic pair plasmas. We find that the fluctuations are consistent with …

D Jiménez, K Kamada, K Schmitz… - Journal of Cosmology …, 2017 - iopscience.iop.org
In models of inflation driven by an axion-like pseudoscalar field, the inflaton, a, may couple
to the standard model hypercharge via a Chern-Simons-type interaction, Script L⊃ a/(4Λ) F …

Prompt electromagnetic transients from binary black hole mergers

BJ Kelly, JG Baker, ZB Etienne, B Giacomazzo… - Physical Review D, 2017 - APS
Binary black hole (BBH) mergers provide a prime source for current and future
interferometric gravitational wave observatories. Massive BBH mergers may often take place …

Connecting steady emission and very high energy flaring states in blazars: The case of Mrk 421

A Dmytriiev, H Sol, A Zech - Monthly Notices of the Royal …, 2021 - academic.oup.com
Various attempts have been made in the literature at describing the origin and the physical
mechanisms behind flaring events in blazars with radiative emission models, but detailed …

Big bang nucleosynthesis limits and relic gravitational-wave detection prospects

T Kahniashvili, E Clarke, J Stepp, A Brandenburg - Physical Review Letters, 2022 - APS
We revisit the big bang nucleosynthesis limits on primordial magnetic fields and/or turbulent
motions accounting for the decaying nature of turbulent sources between the time of …

Numerical simulations of driven relativistic magnetohydrodynamic turbulence

J Zrake, AI MacFadyen - The Astrophysical Journal, 2011 - iopscience.iop.org
ABSTRACT A wide variety of astrophysical phenomena involve the flow of turbulent
magnetized gas with relativistic velocity or energy density. Examples include gamma-ray …
