The Effect of Jet-Ejecta Interaction on the Viewing Angle Dependence of Kilonova Light Curves
Hannah Klion, Paul C. Duffell, Daniel Kasen +1
The merger of two neutron stars produces an outflow of radioactive heavy nuclei. Within a second of merger, the central remnant is expected to also launch a relativistic jet, which…
Virial shocks are suppressed in cosmic ray-dominated galaxy halos
Suoqing Ji, Dušan Kereš, T. K. Chan +5
We study the impact of cosmic rays (CRs) on the structure of virial shocks, using a large suite of high-resolution cosmological FIRE-2 simulations accounting for CR injection by su…
Exploring the epoch of hydrogen reionization using FRBs
Paz Beniamini, Pawan Kumar, Xiangcheng Ma +1
We describe three different methods for exploring the hydrogen reionization epoch using fast radio bursts (FRBs) and provide arguments for the existence of FRBs at high redshift (z…
The impact of astrophysical dust grains on the confinement of cosmic rays
Jonathan Squire, Philip F Hopkins, Eliot Quataert +1
We argue that charged dust grains could significantly impact the confinement and transport of galactic cosmic rays. For sub-GeV to ~1000GeV cosmic rays, small-scale parallel Alfvén…
Black widow formation by pulsar irradiation and sustained magnetic braking
Sivan Ginzburg, Eliot Quataert
Black widows are millisecond pulsars with low-mass companions, a few per cent the mass of the sun, on orbits of several hours. These companions are presumably the remnants of main…
Suppressed heat conductivity in the intracluster medium: implications for the magneto-thermal instability
Thomas Berlok, Eliot Quataert, Martin E. Pessah +1
In the outskirts of the intracluster medium (ICM) in galaxy clusters, the temperature decreases with radius. Due to the weakly collisional nature of the plasma, these regions are s…
