Protruding bullet heads indicating dark matter pull
Uri Keshet, Itay Raveh, Yossi Naor
A clump moving through the intracluster medium of a galaxy cluster can drive a bow shock trailed by a bullet-like core. In some cases, such as in the prototypical Bullet cluster, X…
Advection by large-scale spiral flows in galaxy clusters
Yossi Naor, Uri Keshet
The intracluster medium of a galaxy cluster often shows an extended quasi-spiral structure, accentuated by tangential discontinuities known as cold fronts (CFs). These discontinuit…
Deprojecting galaxy-cluster cold fronts: evidence for bulk, magnetised spiral flows
Yossi Naor, Uri Keshet, Qian Wang +1
Tangential discontinuities known as cold fronts (CFs) are abundant in groups and clusters of galaxies (GCs). The relaxed, spiral-type CFs were initially thought to be isobaric, but…
Compressible flow in front of an axisymmetric blunt object: analytic approximation and astrophysical implications
Uri Keshet, Yossi Naor
Compressible flows around blunt objects have diverse applications, but current analytic treatments are inaccurate and limited to narrow parameter regimes. We show that the gas-dyna…
Magnetohydrodynamics using path or stream functions
Yossi Naor, Uri Keshet
Magnetization in highly conductive plasmas is ubiquitous to astronomical systems. Flows in such media can be described by three path functions , or, for a steady flow, by two…
Compressible flow in front of an axisymmetric blunt object
Uri Keshet, Yossi Naor
Compressible flows around blunt objects have diverse applications, but present analytic treatments are inaccurate and limited to narrow parameter regimes. We show that the flow in…
